Well i have a 225...it took 5 quarts to full line.... As long as its sythetic audi recomends 5w 40 weight full sythetic 5w 30 is acceptable as well.... 0w 40 is a common oil from the after market as well.

 

Hi, I finally got around to change the engine oil and filter along with the spark plugs. I also had to change an ignition coil as one was snapped in half (not sure how the car was working properly). Anyway since doing the changes engine judders at idle from start up and also judders across the rev range. It also feels like there is a loss of power.
The engine also makes a loud rattling noise at idle and whilst accelerating. I have checked all the connections on the coils as there were the only things disconnected. I have not been able to get any any error codes as I dont have a reader and I dont really want to drive it to far to a garage as I dont want to do any damage to the engine.

If anyone could shed some light or provide a solution you help would be much appreciated.

 

Sorry forgot to mention the car is a 225 TT (year200)
