    Yer it's excactly the same has your video mate, aa has been out said it could be timing out or a valve. I had the belt changed about 6 k back, so it can't be that the belts nice and tight etc. Just waiting for recovery then in morning il get the rocker off and investigate.
    Its done 86k now is that about same has yours when it went? We all should defo complain to Audi because it's all BPW cabs what's doing it

    I wouldn't believe the AA guy as they didn't know what was wrong with mine either, get the rocker cover off and drop me a line tomorrow if you need anything pm me. I have a parts list which may come in use.

    Myself and Ron did try with Audi and had no luck whatsoever, I feel it is down to the fact that most cars suffering with this problem are out of warranty.

    ok! update on my motor found the problem its the camshaft its burnt through 2 tappets and the others was on there way out. its generally i common fault with the gttdi golfs 150 they eat camshafts.... basically the mechcanic has said this generally only happens if you use the wrong oil. so if your using halfords special get it out i have used castrol edge 5w 30 since ive had it but obvouisly the prevouis owner may not have... all in its costing me a grand to fix thats including labour using genuine parts. so moral of the story buy cheap, buy twice or in this case buy cheap pay alot out!!!

    The cause of the failures is not the oil as my car had been serviced by dealers and following that I only used oil directly from VW. Apparently this is even different to the 5W - 30 Castrol although Castrol state their oil conforms to the 507 spec.
    I also know of a number of VAG owner with the same problems who have a history of using good oil.
    A number of ideas have been discussed but so far it still appears the original cams supplied by VW have not been hardened correctly.

    Also have a look at the link below if you are interested

    Make sure your mechanic carries out an engine flush and removes all the debris from the oil cam and tappets, even if that means removing the glow plugs and turning the engine over without the cam and hydraulic tappets to ensure the supply holes are clear.

    who are only interested in getting the car thru the warrenty period + 6 months........... any more than that simply isnt their concern.
    why make a car last 300k miles without fault????? no-one would ever buy a new one!
    im surprised audi even go to the expense of making their cars with six digit mileage counters anymore!!!

    what sort of mileage/time gaps are there inbetween servicing? unless its 10k 12 months or less then servicing is to blame.
    150bhp golfs have a more aggressive cam... coupled with the same bs "long life" servicing malarkie...... makes them even more prone to this.
