Quick question:

On a cambelt change are the rollers changed as a matter of course (i.e part of the procedure) or are we just changing them as a preventative measure as with the thermostat, water pump etc.

in short, when audi to the scheduled cambelt change do they change the rollers too. i..e they need to be changed every 40,000 miles?

The tensioners should be changed. If one goes then your engine is just as dead as if the belt snapped. It's crazy not to change the thermostat and water pump while the front of the engine is off. There have been quite a few threads on here about the thermostats failing. Seems to be a fairly common occurence. The interval is now 40000 miles. Reduced from the originally anounced 60000.

Audi will not include them in a quote..

+1,

Not all cambelt changes are the same!

Some Audi dealers leave tensioners and the aux belt off the list to make their quote appear cheaper.

Having my 80K one done at MRC as we speak and they change the lot - to quote here, not all cambelt changes are the same!

questions is, which or what ticks the box for satisfying someones extended audi warranty requirements

OK. I know it makes sense to replace everything. I just wondered if having the cambelt service done for warranty purposes i.e. in accordance with the service schedule would include the tensioner and rollers etc or is it literally just the cambelt.

thats my exact question

to be honest, Audi are such a bunch of muppets, as long as they see cambelt change written on an invoice im sure they will take it as done, regardless of what was changed...

I guess what I'm really getting at is that if Audi are not bothered whether the rollers/tensioner etc are replaced (for warranty purposes) then do they actually need replacing at all!?!?! Has anyone ever had/heard of a roller/tensioner failing? The waterpump and thermostat I can understand as have those fail myself, albeit on a different car.

Not on a rs6 but several on s4,rs4 and a 2.5tdi...Lots & lots on fords & vauxhall....They end up with lots of of bent valves,,

OK thats answers the question. It can happen so best to play safe in my oppinion. Thanks grizz!
