Re: Timing belt - when does it break on a Golf IV 1.9 TDI? (Falp)

You don't want it to break.
First change interval: manual 60,000 miles
auto 40,000 miles
When changing get the 80,000 mile belt and tensioner

Re: Timing belt - when does it break on a Golf IV 1.9 TDI? (strangetdi)

Thanx, I know that.
I want to know if there are any records of breaking here and how many kms.

Re: Timing belt - when does it break on a Golf IV 1.9 TDI? (Falp)

There have been cases of broken timing belts on http://www.tdiclub.com - some of them BEFORE the first scheduled replacement interval. I recall hearing about one that failed at 47,000 miles / 70,000 km. Don't recall whose it was.
Don't even think about going one measly kilometre beyond the scheduled replacement interval.

It makes absolutely no difference to the timing belt what state of tune the vehicle is in.
The power to the drive wheels doesn't go through the timing belt, so as far as the belt is concerned, it doesn't matter how much power is going to the drive wheels.
The load on the belt to operate the camshaft is the same no matter what the rest of the engine is doing.
The load on the belt to operate the injector pump might change a little bit but only under conditions where the "extra" power (over and above normal maximum power output) is being demanded, and even then, it is only a theoretical difference which in reality is likely to be insiginificant.
Previous advice still stands: do not go even ONE kilometre beyond the scheduled service interval for your particular vehicle, regardless of the state of tune. Preferably, do a thorough inspection at each oil change interval, and change it sooner if any abnormal conditions are observed. DO NOT use inspections as an excuse to extend the change interval ... do not go ONE kilometre beyond the scheduled service interval, no matter what else happens.

Re: Timing belt - when does it break on a Golf IV 1.9 TDI? (GoFaster)

The previous owner of my 97 JIII TDI had the belt replaced at 65,000 miles. Is there a possibility that he had the 80k belt installed or is that belt not available for the early 1.9's? I have the receipt for the belt replacement, is there a way I can tell from the belt part number?
Thanks

It is not possible, in your case. The new extended-life belt and tensioner can only be fitted to the A4-chassis cars, and that's not what you have.

Thats what I figured, somewhere else I read...maybe TDICLUB, that you couldn't do it on the A3 TDI's, only the A4.
Thanks
