Please clarify your point.

My point is there's a difference between a safety defect recalls which are mandatory, voluntary recalls, and TSBs.

TC is a safety recall but I've yet to see the update in parts.

So as far as I know the TC is on a 40k replacement interval.

I have a 2013 328i Xdrive. Anything I can do to prevent transfer case? Based on previous owners records, the TC was replaced already at 20k km by the dealer.

How can I avoid this? Does the recall include me?

If you look on another thread the TC isn't the issue. It's the Guibo/CV joint is. That is the recall. Bmw will only replace the TC if the "older" defective guibo has damaged the TC. So unless the TC you had replaced had the old guibo, then you should go back and get the recall for the updated guibo.

I had my transfer case (with old guibo) replaced on Oct 2019. Recall came out in Mar 2020. Had my car taken in June 2020 for the new guibo (confirmed with new part number). Fought with BMW that the TC broke because of the old guibo. After some fight they agreed and sent me a check for $4k.

So to answer your question. It shouldn't break again if you have the newer guibo (yeah right?! Lol). Let's hope the new part will keep my TC in check for longer.

I got mine replaced 2 months ago so I hope I have it. Haven't looked through the paperwork.

I was told the failure was related to the clutch packs slipping or at end of service life even with 44k miles?

I do have a gas engine as well. I believe my last wagon, a diesel, was probably related to the guibo.

Who really knows I guess I'll find out down the road.

Worn clutches will simply throw codes, but will drive exactly the same.. meaning no front wheel actuation. There would be no weird symptoms.

It would drive exactly the same as coding out the front wheels with xdrive.

And that's exactly what happened..

I was reviewing the notes on the TC repair. It was done on August 6 2015. Not sure what proximity this is in relation to the TIS that I have been hearing about.

In the notes, it said

"" removed and replaced new transfer case rubber bushing ""

Am I safe? Is this the rubber guibo? Guess I could just climb under the car.

I'm quite sure you have the old guibo. My TC was replaced in Oct 2019 and the guibo was the older part number. Only way to make sure is to check the guibo part number.

How visible is it? Do I just take off the panels and it should be obvious e.g. I should see a black component near the TC/drive shaft? Do I need to remove anything?

I just did my transmission pan, and while I was there, I do recall seeing what I saw as a dark hockey puck somewhere near the TC and attached to the drive shaft. But that was just a glance, and I could be wrong.

Also, how confident can we be that the rubber + loctite solves the problem?

Called the dealer and they said they don't have a parts list on the work order.

[kdog_x]

If I remember right you should be able to see it after you remove the plastic splashguard under the trans. To replace it you need to drop the exhaust heat shields, because the driveshaft goes above them. But I think if you shine a flashlight over the top of the heat shield you should be able to see the guibo. It's right on the tail of the transmission.

It is either black rubber or gray aluminum, so the difference should be readily apparent.

I'm at almost 80k on TC #3 with the loctite. Still going strong for now! TC #1 was 55k, TC #2 only made it about 30k (this was a rebuild with flange only replacement though). If there's ever a fourth transfer case, I would definitely apply the loctite again.

After all that, I'm not sure if I'd feel better or worse at not getting a new TC... good that yours didn't have signs of wear I guess?

[bringit]

My car has been driving great, I was actually hesitant to have them touch anything. If it ain't broke don't touch it. But, safety wise, after reading all the people with issues, I thought I should take it in just in case.

Same with that other recall I did recently with the EGR cooler one. They basically just inspected and replaced the O-Ring gasket. My car only has 88k Kms (56k miles), it's still in it's pre-teen stage.

[CTMike]

Just got it back from the dealer... took 2 weeks since TC was on backorder. Everything seems to be in order and driving well.

-Inspect driveshaft guibo; has metal guibo
-Inspect flange, some play in flange and slight rust

I'm thinking of getting some 403m rims. I noticed how someone mentioned the rolling difference is 0.3% for the staggered 403m setup, and that the tolerance for the TC is 1%.

Overall, am I safe to grab these wheels without effecting the longevity of the transfer case?

Since BMW sold xDrive M Sports with staggered 403M as an option I think it should be fine.

Just stick to the standard tyre sizes... 225/40/19 front and 255/35/19 rear... in the same brand/spec tyre, and I can't see that causing a problem.

Running 403M myself as standard from factory with 225 upfront and 255 at the rear. My TC failed at 31k miles. So, no, this setup even though it is from factory still produces failed TC's.

Now running 255's all round (square) on my 403M's. TC is still holding up nicely, odo is at 72k miles...probably will be failing shortly after typing this

Is the TC problem a result of the staggered factory setup, or just badly designed/manufactured TCs?


There seem to be many TCs failing on square setups and in USA where I don't think staggered was standard.

There are 2 different failure modes.

1. Output flange for pre-LCI is the most common. This is caused mainly by engine vibration and lack of vibration absorbance by the all aluminum flex disc. This is easily prevented, and even BMW has recommended this fix. The LCI cars generally do not have this issue, and the major difference is the flex disc. (there is a recall/TSB for exactly this, for the diesels)

2. Clutch wear is a more distant second. This seems to have 2 causes. Either mismatched wheel speeds from strange setups/different tires or even vastly different inflation pressures.
The other cause may be an improper actuator calibration causing extra wear on the clutches. I have seen the transfer case module fail in such a way that the clutches are fully locked at all times, and throwing no errors. The driver may notice some weird low-speed wheel hop when turning.



In summary, change to an all rubber flex disk, and investigate all possible issues with differing wheel speeds/circumference and fix.

I wanted to mention that my car has a completely square setup with one of BMWs base rims. My TC failed under the previous owner at 23k km. So far so good though at 77k km. Knock on wood lol

[Onizukachan]

Mine went in for recall, and is getting a new t case. Unfortunately it seems like it will be in shop for a month and I was going to use it to take family to go see Dad for his 70th at end of month.

No major symptoms except some slight surging on full power.
