My chipped 2002 1.8T 180bhp TT has recently been feeling a bit sluggish - It's like the acceleration is gone back to pretty much what it used to be without me feeling any of the power that was once there when it was initially remapped. When i accellerate fully now it feels like the car is being restricted in some way.. like it CAN go faster, but something isn't letting it!
During some light traffic the other day the CEL came on, I used a vag-com cable to read the fault:
17544 - Fuel Trim: Bank 1 (Add): System too Lean
P1136 - 35-00 -
This is the second time this fault has appeared.
I suspected it was the MAF - i used vag-com to take a reading from the MAF while redlining the car in 1st and 2nd gear - in both gears it read 169g/s which I think is about right for a chipped 1.8T right?? I also drove the car with the MAF disconnected and didn't really notice any change in performance.
Can anyone tell me what else it could be?? I did two 0-100 tests last night for the sake of curiosity and they were 7.75 and 7.45 respesctively (the second time i just launched off a bit faster). This 0-100 time seems to confirm the car is running almost like a non-remapped stock 180bhp.
I'm gonna tear my hair out!! Please someone help me before I end up balding myself!
