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...ToyBoy said: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. "
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?hi i have 3.2 petrol with only 68k but i have a fault code with stretched timing chain.is this an easy fix or will it cost an arm and a leg?
