j3nn3r Posted February 25, 2009 Report Share Posted February 25, 2009 (edited) Have had this show up on the VAG-COM its on a A3 1.8 T AGU engine 01247 - Activated Charcoal Filter (EVAP) System Solenoid Valve 1 (N80) 29-00 - Short to Ground 16486 - Mass or Volume Air Flow Circuit - Low input P0102 - 35-00 - 16518 - O2 Sensor Circuit - No Activity Detected (Bank 1 Sensor 1) 16519 - Oxygen (Lambda) Sensor B1 S1: Heating Circuit Malfunction Sensor Heater Circuit - Malfunction (Bank 1 Sensor 1) P0135 - 35-00 - - Been thinking and it had occured to me that the short to ground and MAF may have a common input somewhere. will also check fuses again. I am in the middle of getting a quote for the O2 sensor replacement, but just seems odd to me that these particular errors would show up together. Idle slighty raised also. Does anyonw know if the J17 Relay or any others may be related to these problems. And where is it.

j3nn3r Posted April 20, 2009 Author Report Share Posted April 20, 2009 O2 sensor faulty and fuse for all other errors, causing the low input/short to ground codes Well at least its sorted now.:D Link to comment Share on other sites More sharing options...
torci Posted May 4, 2009 Report Share Posted May 4, 2009 Hi, Last week I've got the same errors from vag-com. Which fuses have you replaced? Only MAF? You mentioned you changed O2 sensor. I don't sense any power reduction or fuel consumption increasing due to O2 sensor fail.. Did you sense the same? Link to comment Share on other sites More sharing options...
venom2 Posted May 4, 2009 Report Share Posted May 4, 2009 im getting the same 1250- ------- Injector for No. 2 Cyl. (N31) Short to Ground INTERMITTENT 1251- ------- Injector for No. 3 Cyl.

torci Posted May 9, 2009 Report Share Posted May 9, 2009 At first I wanted to check fuses of these parts, but I don't know which fuses belong to which parts. How did you found the root cause? Went through electrical parts one by one? Link to comment Share on other sites More sharing options...
