Well have got a problem there as I had the tappets replaced & they checked it & they said it was out a bit but they couldn?t get the distributor to move they took bolt out but they say its seized but they said that the ecu corrects it anyway, they tried to knock it round with a chisel & hammer but it wont budge any ideas & also its a 8v Gti & the manual don?t give you no settings for it as it says it don?t never need doing!
