Firstly a big hello to all from a newbie , just registered 5 minutes ago and i wont hide the fact that im searching for some help . Im trying to help my brother source his gti , he currently runs a mk3 1.8 se and wants to make the step up but is clueless when it comes to cars , hence he s asked me to help .
A good friend of mine at work has an 01 mk 4 1.8 turbo with a revo remap, coilovers , rs4 alloys and full heated leather recaros . He is looking to sell but the car has been parked on his driveway for around 6 months unused, tonight he fired the car up and warmed it through , the car idles fine and apart from the brakes sounding a little rough (surface rust) all seemed ok . Now the car is currently sorn so he only drove it up and down the cul de sac, but hes phoned me to say it doesnt seem to be boosting at all , aparently it feels flat and has no turbo surge , it is however still dumping through the blow off valve. There is no smoke to report of or rough running , he says its driving lovely just down on power .
he has agreed to tax the car so we can take it out for a good run on sat morn and see if that clears the issue , if not i would like to drive the car to my local vag specialists for a plug in diagnostic ..
My questions are ? firstly any ideas on what the problem could be ?
and secondly will i be risking any damage driving the car , assuming no engine warning lights are present ?
prior to being parked up the car had been driven back from the mot station were it had just passed its m.o.t , all being fine at that time
thanks in advance
