hey guys, I'm sure you've heard this one before. I recently bought an Audi A4 1.9 TDI, 2001 model. I cant figure it out why it shakes when is on idle, even though everything seems to be ok when I've tested it on computer.
It is working otherwise perfect, it only starts to shake if the engine is worm. My mechanic is telling me that either injectors or the cylinder heads is broken, but he cant tell for sure....
Any help much appreciated, thanks

...heard that before. What's you location? We don't get TDI in A4 in the states.

hey, I'm actually living in Dublin, Ireland. Recently I realised it takes a lot of coolant, maybe the thermostat isn't working and that could make the engine and car shake...I brought it to a good mechanic today so I'm waiting on a diagnostic

I don't the mileage on your car. However, it could also be your motor mounts since the B5's are aging. A worn mount can result excess shaking during idle.

Thanks Stig, mileage is around 130k...motor mounts were one of the guesses, anyway. Hope to find out the end of this week what can I do about it

The Stig

I haven't experienced this problem with my audi, but motor mounts were usually the cause of excess shaking on my other vehicles. Good luck in your search! Please keep us updated!

Just find out on my car that the shaking was from the throttle body .The throttle is all electronic and when it starts going bad the engine shakes on idle
Replace with a new one and is all back to normal

I'm glad you were able to get the shaking problem fixed. I completely overlooked the electronic DBW throttle body!
