    my tsport thinks its a tdi on starting the car theres a load knocking noise.
    this goes after a few secs as the oil gets pumped round.
    sometimes it doesnt go away.
    it sounds abit tappety sort of thing.
    any ideas

    Mine's a 2.8V6. There's a slight rattle as I start it, & it goes away in a second or so. It's just the bearings turning before fully coated in oil. Nowt to worry about, provided it's not still doing it after ten seconds!

    my s3 sounds like a bag of nails when started, then afer 1 sec sounds 'normal'.

    to be expected on any car with hydraulic tappets.

    Audi18t - you deffinately have something wrong.

    i dont know which of you have the 1.8t with VVT or without but ive found the VVT chain to be the noise on start up, this is because the the chain tensioner uses the oil pressure and being in the head wont have pressure from the second you turn the key, hense rattley chain for second or two /ubbthreads/images/graemlins/smile.gif

    whats the milage? how well has it been previously serviced?
    could easily be a blocked oil guide thats staving the oil to the head.

    just as possible on a high miler though, it could be worn tappets or cam lobes.

    you say its sounds tappetey? it it a ticking/tapping toise or a knocking noise as you described?

    cheers guys its got 80,000 on it had the cambelt waterpump and tensioner done about 5mths ago.
    ill get a oil and filter change and ask my man to check the oil guide and pressure pump.
    its abit weird as sometimes on start up its a 2sec noise and then goes.

    got the engine and gearbox oil changed and they used an aditive for the sticking valve for an extra £10.
    has solved the problem andwhich saves having the valves compressed which i would imagine alot of money.
    next week hes putting it on a valve and injector cleaning machine for £50 as i told him its pinking abit.
    he rekons this should change the drive of the car.
    he disconects the fuel tank and runs the car on hes machine for a couple of hours.
    anyone had this done?
