I just installed my burger tuning stage1 box yesterday.I have 2012 f30 328i and today i have a check engine light. I hooked my obdII scanner to my car to read error. I can not connect. i think i remember seeing something about this box blocks the obdII connection. how can i find out this code on my car.

Thanks

i was able to connect my laptop to the jb4 interface and see rpm data with car on. when i scan for dme codes is says Failed.

i found the code p0440 evap error. This is not a stage one issue. I am trying to reset but my scanner will not reset this code for some reason.

Try uninstalling the BMS. Clear the code. Drive for a bit and see if the code returns. If it doesn't return re-install the BMS. Let us know how it goes.

[Chris@codemybimmer]

BMS stage one doesnt allow you to read codes cause its not connected to the computer no?

[amf]

Correct. If u change to map 0 you can read codes thru obdii port. I'm not sure you can write thru that port. I can read this code but cannot reset it. I need to uninstall the bms and try to reset with my reader.

ok so i removed stage one and cleared my cel p0440 code. drove for a couple of days no CEL. I then installed the stage one again and after about a day I got the CEL again p0440. WTH! I wonder what is causing this.

[Spikey]

what's a p0440 error mean?

[momo3605]

Contact Terry Burger at BMS. He's not the quickest to respond, but I'm sure he'll help you since it seems the code is related to the stage 1!

P0440 EVAP system malfunction

has something to do with emissions.

Perhaps you face a batch of bad petrol?

[amf]

this is my second tank of different fuel.

Thanks for the idea though

[Ouzzo]

I did a quick search for some ideas. I am sure you may know this but you could try looking at you gas cap.Good luck man and keep us updated

so i finally got around to installing my used bms stage 1 for my n26 back in. I ran 2000 plus mile and no CEL and then all of sudden I get the CEL. P0440 EVAP erro. I had to clear CEL.....after about 200 miles.... CEL back same error. I wonder if I got a bad USED stage 1 from a seller on here?

Check if the box from BMS shows any water damage, sometimes if it's not exactly in the right spot it can get wet and cause a malfunction

[amf]

Originally I put it by the master cylinder as stated in the directions. I found it did indeed did get very wet. I took it out for a couple of months. I put it back in wrapped in a rubber glove and zipped tied it in a different spot.....no water got to it this time. BMS is saying i need to send them a bmw specific code (six digit). they suggest I buy some 150.00 cable to read my code. F that.

are you sure this is the st.1 interface ?!

if you are asking if stage 1 is causing this issue then yes I am sure. everytime i run the bms stage one. I get this p0440 evap CEL. if I reset and remove bms I do not get this CEL ever. I stopped running the bms stage one for months and just started again running the bms stage one and CEL is back with same code.

Why would a DME tuner cause a gas tank / gas cap code? Doesn't make sense to me.

Something to try though, leave the blue patch stock as is done for the electronic wastegate. There was an older DME version that ran better that way.

How can you read codes with st.1 ? couldn't do that when I had st.1 box.. maybe the box itself is damaged from water as where it's located all the water drains there, there is another solution if you have a friend with BMS st.1 get the box and see if it triggers same error if so then something in your car if not then if it's me I would upgrade to st.2 & in that case you get a new box then you won't have any problems

you can read codes by changing the map to "0".
