Yesterday I changed my spark plugs and coil packs and before I did that the car was running fine. Well after I did that the car wouldn't start and now I'm at a loss as to what the problem is. Im also getting a "Lost communication with ECM" code. Locks won't work either. What could it be? How...

I have a Mk6 Jetta TDI with a CJAA engine. I've been having a check engine light with codes related to my glowplug sensor. Ultimately I've narrowed it down to the relay switch for the glowplugs themselves are getting no power from the battery with the ignition on and off. I'm looking for any...

So I'm new to this forum, so I'm hoping coming here will give me another outlet for help. I'll give you the short version of my current problem. Just did a complete rebuild on my car (2013 A4-CPMA) upon completion it was running perfect, outside of a pretty decent oil leak. I suspected it to be...

Hi, everybody. I have a 2001 jetta 1.8t wolfburg. I'm having problem with ecm communication. I've done everything I could do that was basic with a test light. I'm buy a multimeter to do other tests. It's cranking but not starting. I've noticed that in the cold mornings. I would randomly come...

I picked up a Golf that runs but has no throttle response. the o2 sensors were **** so I'm guessing it fried the ECU, but I have a few questions. First off, I def want to replace it but I'm not sure if I should gamble and buy one off of Ebay with the immo delete, or if theres an easier way of...
