Richard gave me the interpretation of the codes and I explored all avenues, finally biting the bullet and fitting a new throttle body, as the test maf from my local indie came up with the same fault codes and c.e.l.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi guys this message popped up this morning on my commute to work. Also at some points if i booted it then power seemed to go, felt a bit like someone was hitting the brakes. I changed the maf last year but i wondered if it was with all the heavy rain/wind yesterday?
Cheers
Chris
I think you need to get the fault codes read. ABS/PSM errors when flooring it are often MAF related, but it doesn't sound like that if you have changed it. Did you use a Bosch MAF?
I think it was a bosch one. I just nipped out at lunch and it seemed ok. I have read sometimes the sensors get flooded so i wondered if it was to do with all the rain (my car lives outside).
I had this on mine. Tried all the usual maf tests and had the fault codes read. Richard gave me the interpretation of the codes and I explored all avenues, finally biting the bullet and fitting a new throttle body, as the test maf from my local indie came up with the same fault codes and c.e.l. it started of as a bit annoying and got to the point where it wanted to idle at 1800 rpm. Lost all power on the M3 just as I booted it off the slip road and had abs and pasm failure warnings then it chimed in so I got it up to speed then drove very gingerly to where I was going. After the retstart it was ok for the journey home but then I decided something had to be done. When I took it apart I found that some fathead had fitted a cloth/mesh filter similar to K&N but it was for the carrera with the cut out to clean the ac pump L x W it fitted in the same rectangle but the cut out meant that some of the air was not properly filtered luckily it would only have been at full rpm, but some debis was trapped in the very thin mesh behind the coarse mesh in the filter and it could have been that this deris was disrupting the laminar flow of the airstream into the maf. Anywy with the piping all off and the t/b purchased I was not about to put the old one back in after discovering that, by way of a test, so in went the new one with a new rubber seal and it is as good as gold now. I hope for your wallet it turns out to be nothing more than a dirty maf because a throttle body cost me £670 plus vat.
