P0112 code help

Capn Crunch · 09-12-2016, 12:24 AM

Hey guys. New to the forum. My D has 72,000 miles on it. This morning upon cold start my Service engine soon light pops up with a p0112 and a Pending P0112 code as well (monitored continuously and might clear if parameters allow) I checked it with an Actron scanner and cleared it. Drove around all day and parked at families house for 6 hours or so. After cold start the code popped up again. Is the IAT sensor an issue on the 335D like it is on the 35D? I dont see but a hand full of threads based on this issue and none of them have a definitive solution. I am leaning towards IAT sensor replacement or MAF sensor replacement, but would like to see if anyone else knows more about similar issues. I am planning on doing a DIY CBU clean up after my sons football season is over in late October.

Update:
Replaced charge air temp sensor in cold pipe and cleared the code. SES light came back on upon 2nd start up. Let me tell you what a prime location BMW decided to put that damn sensor with a lock clip. Waiting on my bluetooth OBDII adapter So I can run Carly for BMW (BMWHAT) SO I can pull BMW specific codes to closer diagnose the issue. Should be here today. I have always had a sneaky suspicious feeling that there is a good amount of CBU at 72k mi. I am gathering my tools for a DIY CBU clean out as well.

Ended up being the MAF Sensor.

Shocked to see nobody ever posted anything to help out. Hope it didn't cost you an arm and leg to fix.

$120 for a Bosh MAF sensor on ebay and about 4 minutes.
