2.5 Tdi AFB Engine Trouble

[YORKIE]

Hi all, turns out the luck i had with my previous Audi has just run out on this ONE.
Its covered a meer 150,000 miles (only 900 by me) as oposed to my last petrol that was approaching the 250,000 milestone.
Since i had it, it always had a distinct top end rattle when i switched off, then one day i started it after a short stop( talking minutes) and it started to miss like a delinquent school child.
needless to say i didn't try it again untill i investigated, thought the belt had slipped a few teeth at first, but when i checked it all seemed to time up fine and the tension was good, then as i was looking thru tho oil cap for the cam mark, i noticed something out off place, on removal of the top cover (L/H bank) the problem was clear, several cam followers had de-seated themselves, fully.
thought i'd check the opposite bank and sure enough the same problem, i think there was 9 in total.
on inspection they were extremly worn, but now the cams are also damaged by the hyd lifters contacting them.
what i don't get is why did this happened out of the blue, i had just covered 100 miles sweet. either way it has, is this kind of wear on the followers and seats known on this particular engine, some of the seats were worn almost all the way thru to the top of the valve stem.
i have just ordered the new parts, ouch!!
what i need now is some advice on the timing/ fitting of the new cams. obviously the 2 outers are locked by there respective plates, its how do i time the inner gear driven cams, is there a special setting tool, is done by dti readings???
if anyone knows, or knows were i can lay my hands on an engine manual for this model i would be most gratefull, do any of you work or know someone at a dealer that has access to this kind of info, i tried my local dealer but was directed to the booking in desk, can't afford that i'm afraid. and all my contacts have since left. sorry for going on but its cold now and 4 wheels is preferrable to 2. really hope someone can help, it won't go unrewarded, i promiss.

I'm afraid I cannot help with the info you need, but I shall be interested to hear what those who know, say. Sounds like there has been a great dirth of oil/pressure at the top. What service history has the car? Has someone been putting thick oil in it?
Hope you get sorted soon.

There have been a batch of cams not hardened enough, fitted on this engine between 1998-2000. You will need locking tools to time the engine properly, as its a pain to time by the marks. Also, you will need to do the dinamic timing and thats with vag-com or dealer diagnostic gear ! While you there, replace all the rollers/ iddlers, and the belts + water pump.

Hey Boy, Was Thinking The Same About A Lack Of Oil Pressure/feed To The Top End. The Car Came With Full Dealer Service History So It Should Of Been Looked After Correctly, Will Keep You Posted If I Find A Cause For This, Cheers For Replying

Hey Adam? Sounds Like A Probable Cause, The Cams Been Faulty, They Are Pretty Worn As Well As The Damage Caused By The Lifters, I've Got A Full Timing Kit From Dealers Which Includes New Rollers / Iddlers Ect, Is The Water Pump Common To Fail Or Are You Suggesting To Replace It Out Of Convienience In Its Stripped State? It Seems Ok.
Dinamic Timing, Will The Car At Least Get Me To A Garage Once Rebuilt To Get That Done Or Will It Have To Be Done Before Hand? Ref, Locking Tools, I Have The Sealy 8pc Timing Kit For Changing The Belts, What Else Do I Need And Who Will Sell Them If Anyone, Will It Be A Main Dealer Tool Only? Thanks For Replying So Quick Hope You Can Answer Some More

Yorkie,
It sounds from Adam's reply, as if Audi should be chipping in to help fund your repair. Definitely does not sound as if the cam was fit for the purpose! I should invite their contribution if I were you.
Best of luck and keep us posted.
