Causes my EML, DSC and handbrake lights to come on while driving. Car then goes into limp mode. A quick restart will clear the lights and the car will drive normally until they come back on 10 mins later. Although, when I took a short drive last night around 10.30p none of the lights came on and the car drove normally.
I did some research and some say it is the ICV stuck open (as per code). Others suggest cleaning/changing the MAF, but I also found the bmw equivalent DTC Code:17908 - Fuel Pump Relay Circuit Electrical Malfunction.
Where should I start looking before taking it into an indie shop? Please post links to DIY and/or pix - I would appreciate it. Thanks.
There were some other suggestions about the wheel sensor?? and I noticed, while driving today that my wheel was off-center. Again the p1500 code alluded to the ICV being stuck open. Any additional thoughts?
Well My problem started with a code for the maf . So i replaced it with an oem one. 5 miles later i got the eml and other lights. I read the codes and said jammed icv. I cleaned it . Didnt work. I replaced it, it still didnt work. I thought it was a bad maf so i got another one. Oem as well. Around 300 miles later the same things happened. So were in this together . Back to square one.
OK. So I waited a couple of days before I posted this and I hope I did not jinx myself. Thursday night I decided to look under the hood to see if anything was out of the ordinary. I noticed the cover at the very front of the hood and just above the grill (please bare with me as I don't know the parts by name) that goes into what I assume the MAF?? was not put on correctly. Leaving a small gap for more air to pass through. I corrected this not thinking it would affect anything, but must say that after 2 days of driving no EML+DSC+BRAKE lights. SES light returned, but checked the codes - no p1500, just my typical "lean fuel" codes. I will post if everything changes.
lilbimmer: I hope you have solved your problem, but it seems implausible that that was the issue. The MAF measures air after it has been filtered. Any extra air till the filter is not likely to affect MAF readings. Any experts: correct me if I am wrong?
You are probably right! I know I had to use quite a bit of effort to put it on correctly so I don't know if I "jiggled" anything back into place. Will post if the code or lights come back, hopefully it doesn't.
