Timing belt failure (semi-long)
I'm approaching the 60K service and was talking to Terry Griffin at Griffin Motorwerke about the Haldex, among other things.
He showed me two 1.8T motors that he's working on now.
Apparently, though the toothed belt is not scheduled to be replaced until 80K miles, the hydraulic tension adjuster to the belt fails at around 60K plus miles, sometimes causing catastrophic engine damage. He's recommending that, at the 60k service, I replace the hydraulic tension adjuster with a manual one (and replace the timing belt, too, of course)
I'd be interested if anyone has heard of this problem with the 1.8T motor.

Ack....... major engine failure out of warranty would not be good.
Yikes....
If the unit is replaced by a manual one. How does tension get adjusted. I think I know the answer (Manually)... Seems labor intensive.

The problem is the plastic bracket that holds the hydraulic unit.
It breaks.
I am considering getting a replacement hydraulic unit rather than switching to a manual unit.

I think that's the way I'd go too. Perhaps newer Hydraulic tensioners have
up-rated/improved plastic?
I still have another 25K until 60K so perhaps it'll be a known issue by then.

Happened on my brother in laws A4 at 70K miles.

Needed new engine. Audi basically told him to stick the car up his ***. VW at least has 100K powertrain.
Are we next?
Here is a pic of the belt tensioner redesign on the A4 1.8t .
