hey guys had my car back couple days now after getting a new gearbox!

driving 100mph for about an hour or so, then after getting off at an exit i excelerate to re-join a motorway and at about 90mph the car wont go faster.. i put my foot down and it stays at the same speed, i changed down gears and the car slows down but wont gain speed. i then pulled over and turned it off and drove around smaller roads fr couple mins and the problem stopped, what could this be??

ALSO another problem which has only happened 2twice in the space of 5mins one day was i lost total power whilst driving in low revs, once when turning the car round and second when going uphill back home, the whole car died no power or dash lights. There is no warning lights up or anything.

regards

:S im getting mixed views, some say its a turbo on way out.. others say MAF and more say leak, it hasent stopped since i got the fault code changed.. when at 3k revs in second it blips the power kind of cuts off for a second.. does that help?

Could be a boost leak? Change the MAF and get the turbo air pipes checked. Any holes will take the engine into Limp Mode as that is the way it saves itself when 10 PSi of boost from the turbo turns into 7PSi at the manifold. The difference is too large, so it cuts out the turbo.

You can change the MAF in 10 mins on your own.

spoke to an audi specialist today.. he said it could be a host of things, but is 95% it will be turbo problems, as im going to upgrade the turbo anyway i might aswel wait till i have the doh and get the hybrid lump in it. i was going to do the clutch and turbo recently but a new gearbox killed my plans.

i havent changed the maf sensor or anything as the guy said if u get the new turbo in couple of months it will all need to adjust again so no point wasting the money.
