Seriously, I would get the codes read first...before spending 250 on a MAF. Could be steering sensor, O2 sensor...You have a durametric?...I have one and would be happy to help, but I'm out of town for 2 weeks.

 

I just pulled the codes on mine with the Durametric scanner.

P1249 - 231 - Boost Pressure control deviation
P1101 - 594 - input variable, Charge Measurement

I also just reset them and swapped the Fabspeed out for the exhaust that came on my car, and WHOA!!! I found GOBS of power and response... I was going to take it in to the dealer on Monday evening, But I'm gonna call and cancel and drive the car with the louder RuF'ed exhaust and see how it goes for a few days... I suspect mine has more to do with the Fabspeed and 100Cell catalytic converters not getting along with my combo than anything else... The other system is loud, but atleast I'll be able to hear it better at the track for heal/toe shifting... I'm not joking, I bet I just uncorked 100HP... It isn't even the same car!!

Mikelly, I have Fabspeed moderate exhaust. Is it possible that's this exhaust the problem? I'll test with durametric today or tomorrow to see which code I have...Anyway thanks to all for your help!!!

 

I used to have a techart exhaust which gave me a cell but it's not the psm abs cell so I don't think it could be the exhaust...

 

Yes Dirk, I remember that you told me that TECHART exhaust was bad with cell light. I think MAF or boost leak...I think I will order EVOMS silicone boost hose kit...

 

I agree that it's probably not that... I get my PSM/ABS lights when at the track... The ussually only flash once during a weekend... I get a lot of "low brake fluid" codes, which annoy me as well, but again only at the track...

I just change my MAF but nothing new...

I don't reset computer because I haven't yet the durametric system. Is it possible my new MAF is ok but the lights come back because I don't erase faults codes???

When I restart the car 2 possibilities :

1) light of ABS PSM are gone but my check of computer have them in memory and when I drive again after 1 meter or a few kilometers the lights come back.

2) Light of ABS PSM are there but when I drive 2 meters it's gone again. after 1 meter or a few kilometers the light come back.

 

Sounds like you have other issues... I'd consider taking it in to a shop... I'd also get the durametric software. The ability to do data logging to capture what's going on while driving the car is a very worthwhile tool in assisting in fixing problems... Not to mention the ability to reset these codes!

I am going through a very similar situation. Where the abs/psm lights would go on when the car started, then off withing a minute of driving. Then back on a few minutes later. Now though, they just come on and stay on. I have had in the shop 2 times and have had parts replaced, and it is cleared up, but only for a short time. I will borrow a code reader (not sure which one) from a friend, as soon as he gets back into town and will post any information I can find out.

 

Ok mikeR I'll keep you in touch with this problem!!! Hope we can fix this **** problem as soon as possible because I don't like to drive without ABS&PSM!!!

 

I just come back from my porsche dealer and it seems that it's my ABS with a problem of sensor on the front right wheels with code 4200 and 4201...

 

Good to hear. Glad your car is fixed.

 

Glad you figured it out...got the codes read before you dumped money into a MAF for no reason.

 

Thanks for your help guys!!!
