I am loosing power and the emmisions warning light is on. The power is usually ok when i start the car but the more I drive the worse it gets. The turbo is also there at the start but once the car goes into a sort of limp mode, even with my foot to the ground i get little power. This problem is most noticable when I go on the motorway. After I reach about 65mph something sorts of cuts out and I can barely keep up with HGV's especially on hills.

I replace the Air Flow Meter but no joy so I took it to the dreaded local dealer where they diagnosed it was an N75(wastegate bypass regulator valve) I got this replaced to the sum of £90 but it has not cured the problem with VW saying that it is unfortunate and will have to try something else......

I cant keep shelling out good cash on parts that might not be broken or might cure the problem.

Any suggestions or help please .................................
