hi over the past few days my cars revs have been going up and down and just didnt seem as quick as usual ... anyhow phoned audi road assistance they turned up and said its got to go in for repair ... anyhow i got the car back after just one night and shes on full steam on the paper they gave me back it says leakage on the air intake and breather valve faulty replaced but im wondering is it just wear and tear or is it because i kill it lol i may have to chill on the speed... if so id just like anyone to shed some light on the issue thanks guys ....
