The bearing on the poulie for the cambelt blow-up last week-end....Balls everywhere, they even made some holes on the camebelt itself, the belt was lose and did jump only....1 tooth!!!!! The valves are ok, how f..king lucky is that ?????????????? The all lot was replaced 31000 miles ago in 2003.

When it did happend i stopped the car straight away, called RAC and had the car put on a truck and send straight to MRC workshop. Doug did fix it with brand new cambelt kit ( and water pump.....) , very rare a bearing blow up like that and that one is a very important one....

Car is fine now, many thanks Doug

So guys, if in the futur you hear any noise coming from your engine, just STOP the car, switch it off and get a recovery truck, i am very glad i did it.

Phew! That was a close call Steph - glad she's mended now...

Used to be a ball bearing...

Looks like the smaller idler on the right hand side , never had one fail but i do always change it .

Maybe this is why Audi recommend every 40k for the RS4, whereas the other engine are higher interval?

And Audi don't actually list a Timing belt kit for the RS4 now, so you have to buy all the parts individually.

I did mine not long ago, with the belt, tensioner, roller, damper tensioner and water pump.

Does anyone know if Audi do a metal impeller water pump?

Phew... yes I had something similar but different.... huge relief when its working again!

Yep, had an idler tensioner go on mine...about 90 miles after a cambelt change. Audi UK accepted the warranty and replaced the cylinder heads etc.

every water pump i have supplied from Audi have been with a metal impeller

Does anyone know if Audi do a metal impeller water pump?

OEM Audi has a metal impeller for the water pump, but a lot of the aftermarket kits (especially in the US) have a plastic impeller.

That's strange, I have bought about 10 OEM water pumps and all have had plastic impellers. Just bought one yesterday.
