    Aircon not sorted yet, haven't been able to give the vehicle up for a few days, missus is writing exams. Hoping to take it in next week, but will see. Seems our aftermarket warranty will pay R4500 of that, who knows if they actually will though.

    Yeah, as Marius said, the 3 power/ground cables. I have a cap, 3 farad. I suspect it is too far from the amps, but i have to build something to mount it on to get it closer. Job for the holidays. But want to do the cable change outs anyway, its a fun job.

    Interesting info I got from <snip> regarding a merc ML 320 CDi.

    Owner recalls a glowplug being removed by "mechanical means" (as per invoice) a few months ago on the same cylinder.

    Letter from dealer

    To whom it may concern.

    Mr *********ís vehicle, registration XXX XXX XX, was brought to ****** for a hard

    starting problem. Upon investigation the engine battled to start and had an eratic idle.

    An injector leak-off test was performed and excessive diesel leak-off on injectors 2 and 6 was

    found.

    We then proceeded with a compression test with cylinder 6 having the least amount of

    compression. The cylinder head was removed and cylinder 6 had damage due to foreign object.

    The entire engine was then removed and stripped to determine the extent of the damage, which

    was localized to just the piston and the cylinder head.

    The effected parts will be replaced as well as a set of Conrod bearings, as these were removed

    for inspection, and will be replaced on principle.

    The rest of the engine bolt-on components were inspected for signs of damage in an attempt to

    find the origin of the foreign object. All parts concerned are intact and in working order.

    We have failed to allocate the source, however we have determine there is no component

    failure.

    Thanking you in advance

    i am surprised that the bearings were not replaced. If a foreign object was found then it may have created a sudden stoppage to the piston and so created extra pressure on the bearings of said conrod

    according to the letter they did replace the conrod bearings.

    It's a bit overkill though. My R5 engine's piston that ate the rings looked way worse and the conrod and piston journal was spotless.

    Sounds to me like the glowplugs was originally at the end of their life.

    The workshop made a bugger up in removing them and probably ended up breaking out the glowplug which dropped a tip, or part thereof, in the chamber.

    They then either tried to suck or fish it out instead of taking the head off and making sure all the debris is out.

    Over time the pounding of the parts ruined the piston, injector tip and it would eventually got to the rings as well.

    A particle the size of grain of sand can do major damage over very little time if it doesn't get blown out.

    Sounds very familiar. He just had a little more luck as to the extent of the damage.

    I guess this begs the question, should glow-plugs perhaps not be replaced at a set interval, before they start giving problems, i.e. before thay are brittle whereby we avoid running the risk of debries in the combustion chamber on removal.

    Never removed a glow-plug. Would it be blatantly obvious that a part has seperated? I can imagine if they are removed by force and the whole thing crumbles, it would be very very difficult to determine if all pieces are accounted for.

    Much easier to just put the new one in and give the customer a big smile.

    I think the problem comes when replacing them. I don't think they give hassles while in use.

    I don't want to start another 2SO debate here that is part of the reason I use 2SO is to keep the carbon buildup, which could make removing the glowplugs difficult, at bay for easier removal.

    I should perhaps go and see how difficult it is to remove my old engine's glowplugs.

    I remember though that my new engine arrived with the glowplugs being loose from the compression test organised by the forum members and so far no ill news or shudders.

    I am not touching my glowplugs until they give starting issues. And I'll soak them everyday for a week with Q20 before removing.

    you can see here that the glowplug tip sticks out a bit and I suppose when the engine is cold (rich mixture and glow plug hot) there could easily creep in some carbon deposits where the glowplug sits and bake it in with every glowplug cycle.

    I think you should tip your car upside down when taking out the glow plug , so if any part breaks it will fall out.
    seriously, i would not use q20, its too thick, i would use a very thin oil, like a penetrating oil

    ok, so my ballast decided it wanted to work for a while and then it failed completely.

    Not even the light leveling works. The stepper motor just keeps pulling power until the fuse pops.

    Time to shop for a ballast. They are bloody expensive. If anybody sees a scrapped touareg, audi, seat somewhere, please check if there is a ballast there for sale.

    This is the part

    Or if someone can repair it like this guy?

    Mercedes has had problems with glowplug removal since the OM606.

    You are right Marius, it seems the main reason is carbon build up for the difficult removal. I guess the shape of the orifice where the glowplug sits has something to do with it too?

    The best way seems to be to remove the glowplugs when the engine is still hot. A tad uncomfortable but better than breaking one off in the head and having to drill it out and ending up with something in the engine.

    As per the pencil spots installed on your Toouareg.

    Maybe an answered question:

    But Why is the high and low beams on the "double optic / zenon lights" different in colour?
