    Today, coming home in a snow storm, my son driving and me as passenger, there was a glow plug intermittent light on and a message: engine fault: workshop. There was clearly less than usual power.
    Scan and get the code: P0403 (1027). Exhaust Gas Recirculation Circuit.
    Cleared the code and 2 hour later car not starting anymore. Any ideas?

    Possible Cause:

    Rough Idle Speed and/or Engine stalling.
    Loss of Power.

    Possible Solutions:
    Check/Replace Fuse(s).

    Today I did a check at dealership: all emission system parts must be replaced, 7000$ only in parts. The adviser told me is not worth. He said either to return the car in buy-back program, either go with all emission delete tuning. I don't know what to do...

    Find a VW guru closeby. Clean/ ressurect EGR. Worst case demount EGR, turbo, exhaust and intake manifold, clean, clean, clean , maybe replace egr if it doesnt work after clean. Then get a Dynamic EGR tune from Malone. That will not run you anywhere near 7k LOL.. A new egr valve IF your doesnt get ressurected, is around 150$.. and the work to get parts off and clean, you could do it yourself or get a guru private mechanic to do it. And have him check exacty whats up with it. Dealrships will go for the REPLACE OF TURBO ( like 2k $) instead of replacing a bad VNT valve or such ( copple hundred dollars..). Also dealrships will ask you to REPLACE all emmisions parts, instead of CLEANING THEM. Emmision parts are basically some tubes with exhaust smoke goes through them, or cooland, and one valve ( EGR). Thats it. Dont fall for that, its bullshit.
    I'm assuming the EGR is clogged to the point it not operating anymore because of carbon, wich is an easy fix, you can do it yourself. Find it, take it out, clean, lube, mount back. You cant **** it more its its ****ed already ;)
