335xdrive did you ever get your issue resolved? I am getting ready to this project myself and possibly add backup camera later on but I want to be prepared for any possible issues?

wondering if you ever got this resolved. I can't believe BMW would even make a F30 w/o a reverse camera but discovering if i want to go OEM, i have to add at least rear PDC 1st. This being a $950 option from the dealer, seems like a no brainer

So sorry! Thought I closed the loop with this.

Yes, I did. Two of my used sensors were either bad (even though I could hear them clicking) or wrong type. Ended up buying Chinese replacements from you-know-where and painting them. They were listed as being for the front but work fine. No errors now and works perfectly.

Added factory rear view cam this weekend also. Very nice to have. Re-engineered somewhat to allow shorter, less expensive and much easier to run camera-to-TRSVC cable by mounting the TRSVC in REM compartment.

Thanks for the write up Roxxor....

So i found my sensors on the auction site i guess we can't list here for some reason... I ordered my ENET cable... went to the dealership & they couldn't find this part

- Rear PDC Install Kit - Part #66202339614 - This kit includes the retrofit cable, cable zip ties, and 4 rubber Decoupling Rings which fit around the sensors when they are placed in the bumper. Total paid for kit w/ shipping - $126.86

Is this a Europe part #? if so, my dealer can't order it. Where could i get this from? When i search the # I see it pop up on website but their doesn't seem to be a checkout option... help!!!

I don't know what you would consider reliable, but I happened to be surfing around tonight and found a site i had not seen before...

http://www.bmwstore.pl/pl/katalog/pr...ce-control-tyl

apparently its in Poland and there's a shopping cart and i can add stuff to it. Its weird though because the only thing you can add to the cart is the part that it replaces... which is: Zest. perm. - Park Distance Control, rear 66 20 2 296 99 When I convert PLN to USD, The 503PLN becomes $138 USD, which is the right ballpark. Go to the site and search for the original part # (66202339614) and you'll see what I mean.

Anyone want to be a guinea pig? haha... for the betterment of mankind

Actually, maybe someone on these boards lives in Poland and can do some checking up for us?

[QUOTE=roxxor;15831636]After months of patience waiting for all my parts to arrive, I have finally completed my PDC retrofit and am doing a writeup of the Rear PDC retrofit. This can be done by itself or with the Front PDC(which has a detailed writeup here). I decided to locate and order the parts myself rather than ordering from a vendor as I already have the stuff to do the coding myself, and figured it would save a little bit of money. If you are interested in sourcing the parts yourself, feel free to PM me for details.

NOTE: Like any DIY project, proceed at your own risk. I am not responsible for anything that happens to your vehicle as a result of attempting this retrofit. This information is simply posted as a reference to help others who may wish to do this project on their own. With that said, onto the writeup!

Parts List:



- Sensors (4x) - For my car(Black Sapphire Metallic), the pre-painted sensor part number is 66209261582. Different paint codes will have different part numbers, you can find yours on RealOEM here. However, contrary to popular belief, you can gently sand the color off of a sensor and lightly repaint over it using touch-up paint with no negative effects as to sensitivity, which is what I did for 3 of my 4 rear sensors. More on this in the prep-work section. Total paid for 4 sensors w/ shipping - $170.20

- Rear PDC Install Kit - Part #66202339614 - This kit includes the retrofit cable, cable zip ties, and 4 rubber Decoupling Rings which fit around the sensors when they are placed in the bumper. Total paid for kit w/ shipping - $126.86

- Rear Bumper Mounts (Set of 4) - Part #51128059970 - Unlike the mounts for the front bumper, these are the same regardless of if you have an M-Sport bumper or not. These are what attach to the bumper via adhesive and hold the sensors in place. Total paid for mount set w/ shipping - $20.36

- Rear Electronics Module (REM - This is the module located above the battery in the right side of the trunk - see pictures for reference to identify it) - Please read the Prep Work section before ordering this part!!!! - Part #61359329700 - Depending on which REM you have in your car, you may need to replace this in order to have the correct pin connections for the PDC sensors. This particular part number has the correct pins for all option codes, therefore I found it easier to order this new rather than to search for a module that matched the pins I had, plus the added pins for the PDC. Total paid for REM w/ shipping - $207.68

OPTIONAL - Extra wire connectors(Bushing Contact) - Part #61130005201 - I ordered this out of necessity as I managed to break one of the pins as I was pushing them into the REM socket. These can be flimsy under the amount of pressure needed to push them into the connectors, and since they are around $1.80 each, I recommend picking up a couple just to be prepared in the event you need them.

Total spent on parts including shipping - $525.10

Tools List:
- 8mm socket
- 10mm socket
- Torx set - At a minimum you will need a T20 bit
- Masking Tape
- Rubbing Alcohol
- 18mm Drill Bit - You can use a regular bit or a step drill bit, which is what I used
- Smaller size drill bit - no particular size, just to be used to drill your guide hole in the bumper
- X-Acto knife or deburring tool
- Small Flat Head Screwdriver
- Mini Flat Head Screwdriver - I used this to help with pushing the pin contacts into the REM socket. Picture shown below with a quarter for size illustration


Prep Work:
- The first thing you will want to do before ordering parts for this retrofit is to check your REM module to see if you already have the correct pins for the PDC sensors. Remove the far left connector, and use the picture below as a reference guide. If you do not have the pins in the highlighted box, you will need to replace the REM.



- PDC Sensors - Despite the back and forth on the forums and the internet, I found that while it is not usually recommended, it is possible to gently sand down a pre-painted PDC sensor and lightly repaint it with the correct color code with no issues with sensitivity or distance. This can be helpful in ordering used sensors or ordering black sensors(which are cheaper) and repainting them yourself. In doing this retrofit, I found 3 sensors which were painted white, and gently used fine 400 grit sandpaper to clean off the white paint as best I could from the top and the sides. Then, I used touch-up paint matching the color of my car (Black Sapphire Metallic), and using the included brush, lightly painted a coat of color over the sensor. After letting it dry(30 min - 1 hr) I checked for any unevenness, and if needed, lightly touched up any spots. In the pictures below, you will see the sensor after you remove the paint, and what one of the re-painted sensors looks like on my car. I have tested these using flexible yet stationary objects(hedges, plastic bins) and they are just as sensitive as the factory painted sensors. If you choose to go this route, please make sure you do similar tests with yours after you paint them to make sure they work properly and are correctly measuring distance from objects.




Beginning the Retrofit:

- Disconnect the negative(black) terminal of the battery(10mm bolt)!!

Remove the Rear Bumper:
- In order to make this easier, I removed my taillights during the process. To do this, simply use the small flat head screwdriver to remove the twist locks holding the rubber cover over the bolts, then remove the 2 10mm bolts and gently pull the taillight out, disconnecting the plug before setting them off to the side.
- Next, remove the two 10mm bolts(one on each side) near the top center of the bumper.
- Now you will need to remove the bolts from the underside of the bumper. There are 3 Torx screws in the center area of the bumper, and 4 8mm bolts on each side of the bumper.
- There are 2 8mm bolts and 1 Torx screw holding the bumper to the lining in each wheel well that will need to be removed.
- After removing all the bolts/screws, you will need to press down on the tabs on each side of the top of the bumper(driver's side shown in picture below), then gently pull out on the left and the right of the bumper on the side of the car, and it should come off with ease. I put a thick blanket down underneath the bumper just so that it would not scratch when sitting on the ground.



Drilling/Installing the Sensors to the Bumper:
- I cannot speak for each trim lines bumper, however the M-Sport bumpers on my car came with the PDC Sensor drill points pre-marked which was a great help. If you do not have the pre-marked spots like the ones shown below, you can visit a dealership and take pictures to get a general idea or look up bumpers with the pdc holes on the internet for reference.



- Place a piece of masking tape on the painted side of the bumper. This will help to keep from pulling off excess paint as the drill is going through the bumper.
- Using the smaller size drill bit, drill your guide hole at the very center of the plus sign marking on the bumper, going all the way through the bumper. REMEMBER: slow and steady wins the race here!!
- After you have your guide hole, you can use the 18mm drill bit to drill the hole through the bumper. You may want to stop half way through just to remove some of the excess material that will build up from the drilling.
- Once you have drilled the hole, remove the masking tape from the painted side. Very carefully run the deburring tool(or X-Acto knife if you don't have a deburring tool) around the edge of the hole on the painted side to remove any leftover paint pieces from the hole. You can see the paint pieces/"flaps" that I mentioned around the top and bottom of the hole in the picture below



- Once you have finished clearing away any leftover paint/material from the edge, use the rubbing alcohol on both sides of the bumper where you drilled to clear away any residue from the tape and to clean the backside where you will be attaching the mount for the sensors.
- Place 1 Decoupling Ring around the top of the sensor, and place the sensor inside the mount. Once you have done this with all 4 sensors, test fit them to the holes with the backing still on the adhesive to make sure that they fit properly into the holes you drilled.
Note: When installing the sensors, the end with the connector socket should be facing away from the center of the bumper.
- Once you have done a test fit to ensure the sensors fit properly in the holes, remove the adhesive from the mount and place the sensor in the hole, pressing firmly on the back of the mount for about 10-15 seconds. Make sure you press down on all areas of the mount to make sure you get good adhesion to the bumper. Repeat for the other 3 sensors, and you are done with installing the sensors!

Running the wiring:

- In order to get access to the wiring harness already running into the trunk, you will need to remove the plastic panel on the right side of the car where you removed the bumper, as shown here. Remove the 3 Torx bolts and 2 10mm Bolts.



- Next, press in on the two tabs holding the piece in place, and gently pull down to remove the panel



- Once you remove the panel, you will be able to see the connector that passes the wiring through to the inside of the trunk. Towards the outer edge(away from the center where the wires run) you can use the drill or X-acto knife to make a small hole to run the wiring for the sensors through. You can then use some silicon sealant on the outside of the area you made the hole through to ensure no water gets into the trunk compartment. I would not recommend doing what I did and pulling the rubber stopper out, as it was extremely tough getting it back into the hole.



Replacing the REM:

**If you are replacing your REM, follow these steps. If you do not need to replace the REM, skip ahead to "Connecting the Wiring"**

- To remove your existing REM, disconnect the 3 wiring bundles that are connected to the REM by pressing down on the tab and sliding the "handle" back. The harnesses should then slide right out.
- Next, remove the 10mm bolt that is holding the REM to the car. Be careful in this step not to let the bolt fall down into the battery well.
- Once the bolt is removed, you can slide the REM down to rest on the battery in order to remove the last connection. Using the small screwdriver, remove the red tab that is holding the red battery cable socket in place. Then, you can press down on the tab and pull the cable out of the REM.
- To install your new REM, simply re-connect the red battery cable, place the new REM in place in the trunk, replace the 10mm bolt, and then reconnect the two right wiring harnesses. Leave the far left one out, as you will need it out in order to connect the PDC wires.

Connecting the Wiring:

- In order to be able to add the PDC wiring pins into the far left socket of the REM (Connector A174*14B), you will need to gently pull on the sides of the black connector which holds the brown and blue connectors into the harness, then slide both of them out of the harness.
- For the PDC wiring, we will only be working with the brown harness, as seen in the picture below:



Here is the list of which pins to place in the appropriate numbered slot:
Pin 37 - Ground Wire - Connect the Brown/Black wire
Pin 38 - Inner Right Sensor - Connect the Yellow/Black wire
Pin 39 - Outer Right Sensor - Connect the Yellow/Brown wire
Pin 49 - Power Wire - Connect the Green/Black wire
Pin 50 - Outer Left Sensor - Connect the Yellow/Purple wire
Pin 51 - Inner Left Sensor - Connect the Yellow/Green wire

I have also included the REM wiring chart from ISTA/D as well:



Remember, when pushing these pins into the sockets, be very careful as they are not the strongest in the world, and can easily break. I recommend using the end of the mini-screwdriver to push the pin into the socket.

- Once you have completed adding the wires to the harness, place both the brown and blue harnesses back inside the larger black connector, making sure they lock into place. Then, replace the connector back into the far left socket of the REM.

Finishing up the physical installation portion:

- Before you reinstall the bumper, you will need to replace the plastic panel removed to gain access to the wiring on the right side of the car. Simply lift it up until the tabs click into place, then replace the 2 10mm bolts and the 3 Torx screws. Be careful to make sure you run your wiring harness out the back side of this panel so you are able to connect it to the sensors on the bumper.
- Now you should be ready to replace your rear bumper. Connect the far end of the wiring harness to the far left sensor, and then repeat for the remaining 3 sensors. Once you have connected all 4 sensors, carefully lift the bumper back up into place and push in the tabs along the top and the side. When you have aligned the bumper, begin replacing the bolts and screws until you have completed re-attaching the bumper.
- Reinstall your taillights, making sure you reconnect them to the plugs that you removed when you took them out. Replace the 2 10mm bolts on each headlight, then replace the rubber cover and re-attach the twist cap that holds it in place.
- Finally, reconnect the negative battery terminal, and replace the cover to the battery well.

Coding:
I will add more info on the coding in a day or two, I will go back through the steps and make detailed notes. Basically, if you did not replace the REM, all you will be doing is adding the VO code for the new option:

Rear PDC Only: Option 507
Front and Rear PDC: Option 508

If you had to replace your REM, you will need to create a new Cafd file for the REM(if it is brand new). Once you have done that, or if it is a used module, you will just VO code it to match what you have on your car. Again, it isn't as complex as it sounds, I will write out more details later.

Testing:
- After you have finished the coding, the obvious sign that your install was successful is that when you put the car in reverse, the PDC screen will appear on your iDrive screen.
- Assuming success in the step above, you will want to test your sensors before you start backing up towards solid objects(i.e. buildings, other cars, etc.) by placing some relatively soft objects(see my examples mentioned above in the Prep Work section) that you can slowly back up towards and that won't damage your bumper should you back up too far. Use this as a learning period as well, where once the on-screen display shows red and the tone is steady, you get out of the car and look at how much room is left between your car and the object so you get a feel for distance when you are backing.
- You can adjust the volume level of the PDC alert under Settings - Tone - Volume - PDC. Note that this option won't appear until after you have completed the coding steps above.

And that should be it, time to enjoy your new parking sensors!! If you have any questions, please feel free to ask! [/QUOTE

Thanks for the write up!

I'm in the process of doing mine, I have a problem with rear wiring loom. I went to dealer and they quoted me £230 for the whole loom!! So I got a random loom at a breaker that plugs into my sensors, however, it was cut short, so I extended it by adding extra wire and covering the connections with glue gun ( used tape in my old E87 and didn't work, but after using glue gun it worked fine) Now I'm confused when it comes to connecting it to the REM, as you have mentioned you have a wire for each sensor and 2 for power? I assume that all the power wires to the sensors are shortened to only + and -? Also where do you get the brown plug, and my BMW is F20 do you think it will be the same E Sys changes? Your help is appreciated!!

Thanks

There should be a total of 6 wires, 1 data line from each sensor plus the power and the ground which in the loom are split and run to each sensor. The brown connector is 1 part of the 2 connectors in that specific REM plug, just with the cover removed to be able to add/remove wires.

F20 should be the same as F30 as far as coding changes, however just to make sure, did your REM have the correct pins for the PDC?

Been meaning to ask this for awhile, but can you provide more details about creating the new CADF file for the new REM?

I took a peek at my REM not too long ago, and i don't have the correct pins for the rear PDC retrofit, so i'm going to have to order the upgraded REM for this and i'm a little unsure about how to code something this major

Thanks in advance!

I just checked it today and looks like [Lucky ME ^^] it actually has it, I have already retrofitrd the sensors on the bumper and got the cable in the boot. Also I have ESYS ready. However I'm not planing to get the PDC button yet - would that be okay? And can you please advice me on how to take the plug out (from the bundle)? Moreover I got the cable into the boot from an air duct which it's shown in my pics, do you think it's a good idea?!

That's awesome about the REM! To remove the plug, just press down on the tab and move that black bar up. The plug will come out, then you can slide the two connectors out of the plug.

If you are only doing the rear retrofit, then you will not need the button. The PDC will come on when you put the car in reverse automatically.

Thanks the help, also I have already fitted the front sensors as well, all they missing is the cabling to the REM. Is it going to be the same procedure and won't need PDC button?

Without the button, it would only come on if you put the car in reverse. So yes, if you wanted to use the front sensors while parking, you can put the car in reverse so the PDC display comes on, then go back to drive and slowly park.

Hello mate, today I done the coding, by following the "How to change FA(VO) in F series car 8-24-2013 version" and now when you read the svt the option 507 shows

http://https://onedrive.live.com/red...nt=photo%2cjpg

However when I put it in reverse there is no sign of PDC? Have you got any idea what could be the problem?

Thanks

After you add the new option(507) to the FA, you then have to go back to the list of ECUs, activate the FA(with the new option code), and then highlight and click code for the ECUs affected by the retrofit, which in this case would be the ICM and the REM. After you code those, it should come up.

So the CAFD file for the new REM automatically gets generated once you code that ECU?
Also, what does the ICM have to do with PDC? I assume thats the Ignition Control Module. That doesn't get modified for the retrofit does it?

Thanks, I think after I followed Ur steps. The coding is done now, but the PDC is not working and It shows the message below (In the pic) probs wiring done wrong? However I checked it again and it was all fine. Apart from One problem I have, which is I'm not sure which one is the - or + as I have done the wiring myslelf and cause I left it for so long I have forgotten now, altho I switched between the - &+ yet no results :/
