79 series v8 land cruiser turbo diesel, how do i test the egr valves for possible fault re turbo over boost

Hi, The EGR valve itself is on a set of flexible pipework - usually stainless steel - which runs between the inlet manifold and the exhaust manifold. The EGR actuator valve is pneumatically / vacuum operated by a solenoid valve, controlled by the ECU ( aka the brane). It's not usual for the EGR valve itself to fail, more likely the solenoid valve or its electrical connector getting dirty. If you google for VAG TDI N75 valve you should get all the info you could possibly ever need :-)

Hope this helps, D.

Your public library will have a manual covering your mechanical repair. Moreover, they have the automotive shops online software called AllData. It is the best auto technician database available today. You can print out specific troubleshooting procedures, diagrams, step-by-step istructions, and soforth. The typical person cannot afford to pay for this service, just automotive dealerships, etc... that is why the public library made it available to everyone and for free to view and print out material. This should Fixya! Good Luck!

Please rate my assistance.
