Did a quick Google and found these relating to the VW V10:

"The method used to drive the camshafts is a helical-cut spur gear train provided at the flywheel end of the engine instead of a timing chain or toothed belt".

"The V10 is super complex with its gear train timing cassette design."

If this is indeed the case, I think there's nothing to do!

No need as V10 has no belt


You might find this an interesting read but I have cut a bit out for you for reference - http://www.stealthtdi.com/VWDieselHistory.html

"The method used to drive the camshafts also helps to make this engine exceptionally compact. Instead of a timing chain or toothed belt, a helical-cut spur gear train is provided at the flywheel end of the engine. This is also capable of transmitting the high peak loads that occur in the timing gear because the pump-injector units also have to be actuated. The timing case in which the gearwheels is a high-strength casting bolted directly to the engine's bearing tunnel as a means of attenuating the transmission of noise to the engine block. A plate-type joint in the timing gear compensates for the difference in thermal expansion compared with the aluminum engine block. From the timing gear, intermediate shafts and gears drive the auxiliaries such as the air conditioning compressor, power steering pump, water pump and 190 Amp/h alternator. "

But for anyone who does have a car with a cambelt, most manufacturers have considerably reduced the recommended mileage AND they recommend a time limit of 5 years as the belt can perish even if you've not done the mileage.

This also is one of the reasons for the oil being specified 506.01 for the V10 as the wear on the cam injector units can be quite high...
also the reason wear is disproportionate if the wrong oil is used..

Haven't seen this prob on a Treg before, but the same engine has been in the Golf etc for years, so I'd run it thru google or VW vortex etc for some inspiration.

Sorry I can't be of much help with your prob, but sounds like it needs fixing before you go anywhere.

As an FYI, only the V8 non FSI lump has a ye olde poly belt. V6 3.2 and 3.6 has a timing chain, as does the FSI V8, 2.5 and 5.0 are gear driven

And the 3.0:

Woah ... engine porn, hfg?

Wait a minute ... think I've got a bit of chubbiness going on.

Ahem. Pure filth - you should be ashamed of yourself.

Hello Fitz, I had the same problem last year. Cost me £2000 at dealer. Engine & gearbox out to replace belts, tensioners etc. I am interested to know how you got on?
