popping exhaust?
havent had my seven long so not sure if its meant to do this, was going down the motorway and as i put my foot down and went through the gears the exhaust kept popping a lot, and when it popped the car felt like it was stuttering, like power was going on off on off, what causes this??

yes, you are running too rich and the excess fuel not burned up in the combustion process is getting pushed out the exhaust. Happens more on cars with catalytic converters but mine pops a little too.

1. Change oil/filter
2. Change fuel filter
3. Flush coolant
4. Change spark plugs and wires
5. Change O2 sensor
That will give you a good basis to start with. After that, if you are still having problems you can diagnose them from there.
