So... doing a few pulls to check out the turbos, and I get the PSM/ABS lights, and the Durametric tells me I have a bad MAF. Thinking about the Porsche equation, then:

PSM + ABS = MAF

I had to figure out a set of numbers where each letter stands for a unique integer that fit the equation. All you geeks out there have done these puzzles before. There is at least one solution.

I think I need some track time real bad!

 

I got the same problem last night.
But it recovered after I restarted soonly. Mine is 02 996 TT.
The dealer told me that the ABS and PSM were triggered or powered by MAF.
So... I got the MAF problem also.
They said it is because of the air filter ( Kn'N ). If I change it back to the original one, it won't happen again. But I think I could stay with it, untill it really doesn't work.

 

The PSM/ABS lights can come on for a wide variety of reasons. You really have to read the codes to know. It's often the MAF, but not always. Sometimes it can be cleaned, sometimes not. The MAF takes 5 minutes to change and costs $200 or so, and controls the fueling for your engine. Anyone can do it. You do need a special torx head with a hole in it, but these are readily available at hardware and auto stores.

I'm advising don't get used to it - find the problem and fix it.

BTW, the solution to my math problem above, which drew ZERO responses, is

417 + 321 = 738
