yes maybe however i think all the other issues with the car have made the engine fault seem massive,i am sure it is a minor thing as i went on holiday to the new forest and drove 870 miles average mpg 38 and the car hardly missed a beat,many moons ago a mate of mine had a series 2 rst which wouldnt start,and i jest you not 6 weeks at the dealer and a final bill of 1700 reduced on complaint to 1300 he got the car back and it was only worth 5000 tops so am a bit concerned about handing it over to a vw main ,i mite consult a local garage with lower labour rates with vagcom and maybe agree a top price of diagnosis,vagcom has al;ready pointed out missfire on no 4 cylinder but coilpack change and spark plug havnt altered the fault
