Pump is not timed to the engine.
This is my first TDI, and I might have read something wrong... So, remove the belt and replace it? Sounds good to me.Pump is not timed to the engine.
10 years and 130,000M of high heat will do that.This has me curious as to what sort of conditions this car was subjected to that the belts are bad like this
2012 Touareg CATA 192k,. Im fixing to change the timing belt on the pump myself before 200k .. I ordered the lockout tools off amazon which included Im assuming some others for different models.. Still trying to find a procedure on locking the system and changing the belt and tensioners.This is the only reference I can find to changing the V6 or V8 TDI HPFP belt and tensioner. These are not listed as a service item by VW but they clearly have a finite life due to belt wear and aging and the bearing in the tensioner pulley wearing out. What experience do people have of these failing and needing to change these apart from this single post ? cheers Rohan
Yes I have the Erwin download and unfortunately there is no data in either the engine or fuel system or maintenance sections on the HPFP tooth belt drive life and recommended maintenance. There is also apart from this one thread nothing I can find on peoples experience with any HPFP drive belt failures and maintenance. Fortunately my Treg has only done 100k kms but it is now 10 years old. I am trying to put together the maintenance plan for the next 10 years and i am struggling to find information I can rely on around this item.erWin has all the service information you need. If you don't want to pay, use the search function and find gifts from others, both on here and many other (typically russian) sites.
Significant damage?Well, if it were mine, I'd treat it just like a timing belt. It is essentially the equivalent of one, and if it goes to crap, it does significant damage. Remember that belt degrade, and over down under you probably have lots of heat and stuff so you may want to bite the bullet and do it as PM instead of waiting for the big bang.
Just curious what damage there would be? It would simply stop running.Guess not. Just wait till it lets go and simply replace it.
