I can make these two lights come on when I accelerate or turn agressively. So I started looking for low fluid levels. Checked brake fluid level thinking maybe it is low, no help. Found my battery very low and thought this could be it but , no help.
This does not seem to really turn those things off, I still feel the ABS working. Any suggestions???

 

Two words...POS MAF!

 

I had that happen when my steering sensor was out of whack. Did you hit a big pothole recently?

 

Actually the first itme it happened was at the drag strip. I know, I know but I thought I would try it once in my life. That is why I have been chasing fluid levels. Did not run the car that hard, 12.8 sec.

 

These do reset everytime I turn the car off. I manage to turn them back on almost every trip.

 

Sounds like there maybe a battery charging issue, as if the system sense a low voltage or a charging system problem it will turn off ABS and PSM first to conserve battery life. Have you check your battery's fluid level? You mentioned that your battery was low, so that could be a tell tail sign.

 

I thought so too and did top off the battery thanks. Really had some hope in that one. Keep the ideas coming

 

Len,

Another thing that will turn off the ABS and the PSM is the brake fluid level. It is possible maybe you have a defective fluid level sersor? Try to jumper wire it first to bypass it and see if that helps.

 

This may sound crazy but take it to a dealer and have them hook the computer to it, you'll find out exactly what's wrong.

 

Robin,
I did fill it but maybe the sensor is intermittant. I'l try the jumper.
Riad,
Did your lights reset with restart when you had the steering sensor go bad?

 

Yes, I believe they went off.

 

This morning I was accelerating on a on ramp in third at 6000rpm. My car bumped back like the fuel cut hit but thats impossible at 6000rpm. Then my ABS, PSM and CEL lights went on. I know my CEL is from my POS air intake(every 48hrs). PSM and ABS is a new one. I just bought this car from a Porsche dealer last month w/ a 100000 mile warranty. Do you think they will bitch about my my airintake and try to void the warranty? Also do I have to pull the negative to clear the lights?

 

PSM and ABS are staying on? Mine reset every restart. But now they come back at first decent acceleration.
