Hey,

my V6 has a strange noise. Can be heard only when the engine is warm.

While running:

When stops:

These have been replaced 7000km ago:
- cambelt + tensioner
- V-belt (rollers no, but tensioner has been replace 2000km ago)
- water pump

Airco is out of order due to a broken pipe. V-belt, water pump, servo pump, alternator and airco compressor have been checked in a workshop 2000km ago, and theoretically these (the bearings) are OK.

Any idea?

Yes. You may need to lower the engine mount, depending of the size of your socket set - with a low profile 1/4 inch drive, you can do it without fiddling with the mount. You will need to remove the aux tensioner.

I would take the plastic cover off, and look at the belt. Sounds a bit like it is rubbing, if it is worn, narrow, do not start the car, get it replaced!
