Thanks Rick, it is definitely the "0" button. It confirms the Service message I am getting. The indi just forgot to reset the FSS, I guess.

The MAS is about $240 where I live and the labor was about $100. The symptoms were, I would get cruising about 60 mph, and then press the accelerator and it just wouldn't go. It would eventually accelerate, but very, very slowly. I couldn't really tell anything was wrong below 60 mph, because of the lag inherently associated with turbo boost. You should be able to tell if it is MAS from your acceleration. It literally feels like something is physcially holding the car from behind when you goose it. If not, I would say you have some other problem.

Hope it is not bad--let me know the diagnosis if you don't mind.
