I recently replaced the front pipe (also called an "intermediate" pipe or flex pipe) on my 1.8T exhaust. To do that I had to remove the catalytic converter. While I had it out I thought it would be a good time to recoat the o2 sensors with antiseize since they're the original sensors 15+ years...

I just picked this car up yesterday, 3 hr drive to get it. 42K miles, veryu clean. the dealer that sold it said they just replaced a rattling converter on it. They got a check engine light, R&Rd the sensors, cleared the codes. they thought it was "leaking" exhaust at the sensors. I'm supposed to...

Yesterday I was caught by surprise when tried to start the car (1.8T 2002). It took several attempts to crank the engine but then instantly got the EPC light and high idle. Based on what I read in the forum, the culprit should be a bad crank position sensor. Is that a right assumption? Or should...

I have a 2012 VW Passat 2.0 TDi Station Wagon and I am having issues with the dashboard being festooned with the ABS, Power Steering, Traction Control etc yellow warnings and have traced the issue to no signal from the rear left ABS Sensor using VCDS.

Hey team, I believe that I have 2 bad knock sensors on my 2003 passat v5. I am keen to try and replace the sensors myself but I'm struggling to find any info on where they are located. Also once they are replaced will the ecu need any sort of rebooting/ calibrating to work with the new sensors...

Removed the Tork head bolt and I can rotate a few degrees each direction but refuses to come out even a little and I cannot really see anything. I understand there is a ring-rubber seal which is probably the culprit. But any ideas how to make something to exert more power that my hands have...

My problem is, I replaced my wheel hub due to bearing failure. I destroyed the original sensor when removing. I installed a new hub with a new sensor. I have an abs fault now with the wheel speed sensor. I thought that I may have bought the wrong sensor so I replaced it with another new sensor...

All, I purchased a used 2002 VW Passat (30v V6) for my son that wasn't running at time of purchase. I bought it as a project car for he and I to work on and have it be his first car. The timing tensioner pulley had failed and wrecked both heads. I've been able to navigate that and have...
