Timing chain noise 2.7 v6 tdi

[taximeistergolf]

I have an 05 plate A6 2.7 Tdi, which unfortunately over the last couple of months developed what I can only describe as a clatter which lasts for about 2 seconds on start up. I am almost sure that it is one of the chain tensioners losing pressure when the car isnt running, and therefore renders the timing chain slack momentarily on start up. I presume the oil pressure thsn kicks in and actuates the tensioner hence removing the slack.
Can anyone advise me if this is a common problem, and if any harm will be done if left untreated. Thanks in advance.
p.s. The car runs beautifully once started, and it only clatters when left for more than about 20 mins

right bank tensioner (os) but very rarely causes any damage.
The tensioner has been modified so if you purchase a new one it will fine and it can be replaced in situ

Any idea if this can be changed without removal of the engine? Thanks

[a8 tech]

yes it can be done in situ, allow 3 hours and you need the crank locking tool and camshaft tool

Thanks for that. Visited the local dealers, and they are quoting 27 hours labour for engine out, etc Do you know of any good technicians that would take on this type of job locally. Cheers

A8 Tech is fairly close to you geographically, and if he says it can be done with the engine in situ I'd take his word over your local dealers. He may be willing to take the job on if you ask him nicely? Worst case is he says no...

I would but I only under take diagnostic and retro fits at the weekend.I would re approach the dealer and ask one of there more technical staff to assist the booking clerk as its 3.7 hours labour to fit.If they are still unsure quote technical bulletin 2012744/6.
Labour time repair operation number is 15 36 19 44 = 3.70 hours

Please do not take a copy of this with you but simply explain this to the booking clerk who will double check for you and confirm the cost.
Allow extra cost for the gaskets etc

Hi Rallyboygower

I had chain rattle on mine... an A6 Avant 3.0 TDi occurred at about 73-75K on clock... my symptoms where only at start up for 1-2 seconds...

I've just had fix for all chains & tensioners, HPFP belt & tensioner, AUX belt & tensioners, Tiptronic oil change as well price was £2.2K inc VAT

As engine is removed they did a oil change, coolant change, re-gas of A/C system

These are P/N and supersession history

057 109 218 G DROPPED 01/10/2005
057 109 218 J DROPPED 01/12/2006
057 109 218 K CURRENT

Even though my car first registration was 09/2005 many parts have production dates of 6-7 months before that
So going only by my personal experience I think your car qualify having suspect tensioner
My advice and as you can tell from others posts in thread get checked and done

£2K is big bill but if you take out full service cost which you getting then £1500-£1700 is not bad price for amount of work...

Hi gupsterg
Thanks for your reply appriciate it, can't understand how the noise Goes after 1500 rpm possible taken slack up?. Only thing I am going down Cornwall Saturday morning in my caravan for 2 weeks hope to god it holds out for that!! Think it will? When your going can't hear anything only when you pull away I can hear it?
Wish me luck guys!!!
