Hi Guys
this is the second time in a month that my A6 (03) suddenly started shaking. Last time it did that I took it to dealer and he had to replace 2 ignition coils. The car is over 80K now. anyway, I am looking for an advice if I should be taking car back to the dealer/ mechanic or replace the coil by myself (if its easy).
The other tung is I am not sure if its coil issue again but it appears to be the same. any suggestions. thanks
