Hi there, wondering if anyone can offer any insight in to why my V reg A3 is misfiring. Trustworthy garage has change the coil pack and the plugs but it has made no difference. There is also no warning light from the engine management system. Any help very much appreciated!

 

I had a similar problem with a 1.6 lt A3 (2004 model) and after I had the fuel pump changed the problem was solved.

 

Just getting familiar with Audis but on most cars could be a number of things. My first thought since coil pk n plugs is a burnt valve. There again I'm new to Audio world so I'm sure some one else can better direct you.
