Guys, I was driving casually last night and all of a sudden the PSM OFF and ABS lights came on. The car drove fine, then this morning the CEL also appeared, still drives fine. The driver info says ABS is disabled and to check the engine and take it to the workshop...I would love to know where this workshop is.. ha. Anyways car is stock with 16k miles. It's going to the dealer tuesday anyways but just looking for idea of what could be wrong..thanks

 

MAF most likely

 

Thanks, I know the purpose of the MAF..but wouldnt the car run differently if it was defective?

 

Is your car stock...When the MAF goes (as your symptoms do imply) the car will go into limp mode, but ironically it will still boost...to up stock levels. I bet MAF.

 

Yes it is a creampuff...

 

Mine is doing the same. I took it to a track day and now the ABS module is leaking slowly from the underside into the front trunk. The fluid level sensor and ABS module will throw these lights as well. Check the fluid level in the main brake resivoir and if full check to make sure that your ABS still functions properly.

 

Mass Air Flow

 

will the tecks at porshe know if the maf is bad if the hook it up to a computer

 

Maf !!

 

Mass Airflow Sensor = The device that measures the amount of air / density of the air that is entering the engine.

 

Or a blown hose, same symptoms on a friend's 996tt, turned out to be one of the IC hoses that had cracked and leaked air on boost.
