Got check engine lite solid

[Wizzard1]

Car is driving and shifting smooth (tiptronic) and auto. Brought it up to about 94 today in auto mode and put the petal down, did feel the down shift and then check engine light came on. Doesn't seem to be affecting drivability.
I just purchased it, 2003 with 26K, then had it checked at Foreign Affair Motorsport in Pompano beach. Oil just changed, brakes bled, got a clean bill of health.
I'm thinking it's the MAS, and new Air Filters.
Any recommendations?

Yeah. Read the CEL code.

Where is it, do I have to plug into the onboard diagnostic port. If so what's the best one to get.

Take it to Autozone, etc. and have them pull the codes for you. They will usually do it for free or loan you the tool.

You can buy a simple OBDII reader for under $100 anywhere. That will allow you to read codes and reset simple things.

Or you can spend +/-$300 for a Durametric and really tunnel in to Porsche specific issues. You will need a laptop that meets their requirements for it to work. It is a software and cable package. Diagnostic Tool for Porsche | Durametric

Get the codes and then use the search function to do some background reading and then follow up with questions. Good luck.

I bought the cheapy reader from HB for $50 then I see them clones on EBay for $39. Basic is good enough for most codes as it will lead you to the general problem area. It will tell you readiness codes for smog too.
