I have a 1.9 SE TDI with a power problem. Got it on to the vw diagnostic, which showed possible problems as MAF, Coolant Temp Sensor and Boost valve. I have replaced the first two, but haven't cured the problem, still going in to limp mode at 60mph. Now want to replace the N75 valve. Can anyone give me a description of where it is and what it looks like. is it easy to replace. A picture would be great. Thanks.

Is this a B4 generation Passat? If so, the N75 valve is on the firewall in front of the driver.
If it is a B4, replace the piece of tubing inside the ECU, and the hose from the upper intercooler pipe to the ECU. Along with a new N75, it will cure your limp mode problems.
