    Hi all,

    Over the last few months, I've seen the DPF light on my 2009 1.6 Tdi Bluemotion Passat come on and off. Sometimes a few seconds.

    Today I started the car and it was in idle for a minute or so. I took the key out, got back in the car (forgot my wallet).

    I started the car again and noticed:

    1. The Engine Management Light (glow plugs) was flashing
    2. The Emissions Control Light was on/solid.
    3. The DPF Sensor light was not on.

    I tried to drive the car but it was clear it was in limp mode and not a good way to try and start a motorway journey. Incidentally, it was a week ago when I was on a 2-3 hour motorway drive.

    I happened to have a cheapo OBD2 scanner and it read the error as P2463. I couldn't clear the error for some reason.

    Now I don't know what to do.

    Should I attempt to do a "Diesel Particle Filter Emergency Regeneration" or is that too risky or even worth doing?

    Thank you.

    EDIT: Also, is there anyway to come out of limp mode without a VAG machine? I can't find anyone local who would do it for me at an affordable price.

    You need the ash mass and soot loading values checking in Measuring blocks, if the loading is over 40% the ECU will not allow even a service forced regeneration and the DPF will have to come of and be cleaned so that when it is put back on a service regeneration can be carried out to finish the job.
    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.
