996 TT Check Engine Light- misfire

[jcam]

When the check engine light came on, my mechanic plugged the car into his laptop and got a misfire reading. Since the car was not due for a plug change, he attributed the misfire to bad gas and drained the tank. That didn’t fix the misfire light from coming on and he accordingly changed the plugs. After changing the plugs the misfire reading still appeared which led to changing out the coil packs. That didn’t fix the problem either, so he borrowed an ECU from another TT and put it in my car…NADA. We’re currently scratching our heads wondering what is causing the problem. Anyone else experience this?

Please list the fault codes associated with the CEL. Thanks.

Sorry to hear of your misfortune, but as Loren says...get the actual codes and post them hear or before you know it your "mechan-hack" will be replacing your engine.

Guys, sorry about the delayed response. Spoke to the mechanic today and he didn't recall the numeric portion of the fault code and said that the description of the code read "misfire". He also said that the problem has been fixed and that it was a broken cam lift bracket and that when the car was attempting to shift into a higher lift cam, it was causing the "misfire reading".
