    hey there my speedos out wat seems to be about 20% or so. ie if it reads 25mph ur doin 30mph, if it reads 60mph ur doin just over 70mph. makin speed cameras a right **** to go through lol

    anyone heard this prob before? i cnt seem to find out wat it might be. garage is lookin at it tues n reckon it could be the gearbox sensor. any help would be much appliged.

    btw its a 98 a3 1.8t, completely standard. ta

    What wheels and tyres are you running? Could be that the overall rolling circumference is out

    Sounds like you may have the wrong tyre size on, which will knock your speedo out....
