I will check that thank you for you help kind regards wayneCheck the air pipe from the turbo as it enters the intercooler. There is a bracket locating it onto the sump. Quite common for garages to not disconnect this clamp when they lower the engine to access the cambelt. This either breaks the bracket or loosens the pipe causing an air ( boost ) leak. If the bracket is damaged this then puts stress onto the lower end cap of the intercooler which then splits and blows out the seal..
Will do but it’s going to be the weekend Time I get round to check the pipesCheck all of the vacuum pipes coming from the N75 valve. They can perish and a leak wouldn’t be immediately evident.
It gets to 3000 rpm ok but after that you have to change gear my clocks on the a2 only go up to 5/6 grand it sounds like the engine going to blow up after 3 grandI had the same problem on my atl and it was vanes stuck on the turbo, only relevant if you have an atl engine guess.
When I changed the turbo I had all the vacuum pipes replaced with samco silicon for £20, worth it for peace of mind and not having to trace a small leak in the ancient originals. Does it cut out under heavy load or at that rev range regardless of how you get to 3000 rpm? Could be boost pressure mis- signal throwing all the calculations on the ecu giving limp. Does a restart fix the turbo back to normal?
