P1138 P0327 P1136 98 2.8Q
So, I had a friend of mine who has the vagcom software and a cable, check my a6 for error codes, since i noticed that the CEL never ever lights up when turning the key on ON position.
here's what we found: VAG-COM Version: Release 409.1-US Control Module Part Number: 4D0 907 551 AH Component and/or Version: 2.8L V6/5V MOTR AT D03 Software Coding: 06252 Work Shop Code: WSC 02325 5 Faults Found: 18010 - Power Supply Terminal 30: Voltage too Low P1602 - 35-10 - - - Intermittent 17544 - Fuel Trim: Bank 1 (Add): System too Lean P1136 - 35-10 - - - Intermittent 17546 - Fuel Trim: Bank 2 (Add): System too Lean P1138 - 35-10 - - - Intermittent 16711 - Knock Sensor 1 (G61): Signal too Low P0327 - 35-10 - - - Intermittent 16826 - EVAP Emission Control Sys: Small Leak P0442 - 35-10 - - - Intermittent VAG-COM Version: Release 409.1-US Control Module Part Number: 4B0 927 156 G Component and/or Version: AG5 01V 2.8l5V USA 8509 Software Coding: 00000 Work Shop Code: WSC 00000 1 Fault Found: 00526 - Brake Light Switch-F 27-00 - Implausible Signal Since i just bought the car, we cleared all the codes, waited a week or two, and we just rechecked yesterday, and 4 codes still come in: 17544 - Fuel Trim: Bank 1 (Add): System too Lean P1136 - 35-10 - - - Intermittent 17546 - Fuel Trim: Bank 2 (Add): System too Lean P1138 - 35-10 - - - Intermittent 16711 - Knock Sensor 1 (G61): Signal too Low P0327 - 35-10 - - - Intermittent 00526 - Brake Light Switch-F 27-00 - Implausible Signal I have a small exhaust leak at the flexible part right before the catalyst canisters, but i was going to begin by checkin all my vaccum lines. what else should i be checking ? MAF ? o2 sensors reactions while running? coilpack ? thx |
forgot to mention that the car sometimes (quite often in fact) hesitates while accelerating smoothly.... if i floor it, it will take it but the car will still sometimes hesitates, sometimes not. there is definitely an intermittent loss of power.
The motor seems to rough idle just a little bit (just enough to make the car shake a little, like +/- 100rpm). This problem is also intermittent.... and what about the implausible signal on the brake light switch ? ?? thx a lot! |
Knock Sensor 1 (G61): Signal too Low
the implausible signal on the brake light switch is a result of not depressing the brake pedal during the scan.
