Hi all, I have 53 plate Audi A3 2.0L Petrol, I was having an issue with the car when First starting driving, after a few minutes driving the car is loosing power and very very slowly accelerating it will then misfire/chug and come back to life and then go back in to slow mode (as i call it) its doesn't do limp mode where it wont go over 3000rpm it will just accelerate extremely slowly till it chugs and comes back to life. Please also note after anything between 10-25 minutes driving the problem then goes away completely.

So first of all i changed all of the sparks plugs, it still continued to happen. I have now changed all of the ignition coils and its still happening.

Any advise would be greatly appreciated.

Many thanks in advance

Joe
