i am a newbie with a 1.9 tdi 02 plate a3, with about 137,000 miles. The problem i have is a juddering, which no one can diagnose. I have searched this forum to see if any one else has exactly the same problem but mine seems ot be a combnation fo everything! So just wanted a pointer please
My was has been on the VAG machine no problems reported. My engine managment light is constantly on. The car judders/vibrates all the time but reduces as you go through the revs.
I have replaced the temp sensor. Heres the wierd part. The car now judders all the time, but lets say i go a few miles away and switch the engine off and i quickly eg go into the shopand get back in the car then sometimes the juddering stops and the car works smooth as a baby! This has made it a nitemare to diagnose as sods law whenever a mechanic gets in it works! I drove it to leeds and back (about an hours journey and went on motorway to test it workd fine)
I dont think its the flywheel, its almost like the car isn't 'breathing' properly. The engine is vibrating and shaking loads. I was wondering if it could be the air flow connector (the air flow thingy has new filters) if the car is revved or used for more then -10 mins or revved then the temperature jumps up to 110.... before I replaced the temp sensor it was getting upto 120.
The question is what to do next, dont want to spend loads as cars only worth a few grand and looking to replace anyways.
any help would be appreciated!!!
