Hi there,
New to owning and audi so please be gentle. I have a S6 2.7 Sline and recently iv had a small judder while the car is cold. I put to a garage who just assumed it was an injector problem.
iv been told this is quite rare for an injector to go and more likely it would be a loom wire.
The Car runs fine, starts on the button cold and warm with no problems, no spluttering.
The juddering stops when car is up to temperature and when I say juddering I mean the mechanic didn't even notice it until I pointed it out. He listened to the engine and couldn't hear anything untoward.

I'm not a car person at all, as much as I love my audi I'm not mechanically minded and I am just hoping for abit of information to possibly arm myself with before i go to the garage.

thank you for any help.

1st did he actually log anything to denote which cylinder it is, if so then move injectors about & see if it stays or moves with the injector.
