My 03.5 P5 doesn't have ABS, so it isn't standard equipment. They should be able to tell via the VIN. Why not ask them to prove your car doesn't have ABS?
I got the same intake w/ no problems.....after I reset my ECU.
you should go back to the stock intake, reset the ECU, then see if you get a CEL again.
If you get another CEL while stock then it's not the intake.
good luck!
