i have got a fabia rs on a 05 plate and i have got a issue with it thats driving me mad if you give it some welly from stand still when it hits 3000rpm it just loses power and starts to kangaroo jerking up the road until you let go of the accelerator if you re apply its is ok it does not do this if you drive it up through the rev range slowly and is also ok if you are on the motorway and welly it in 6th if you have any ideas i will be gratefull for any responce this is now doing my head in

you will need to get the codes read either at the dealers or by someone with VAG-COM
