Hello everybody,

I would like to ask some help for you...

I have a Stilo 1.4 and few weeks ago I experienced a strange sound into ribbed belt drive system. When I put off the belt, this sound is out.

I have changed climate compressor bearing in the belt disk, belt tensioner bearing (not the complete tensioner, only bearing) and crank shaft belt disk. This sound comes in around 1400-1600 rpm and it seems like a woodpecker knocks the wood If I rpm speed up or slow down the sound follows the rpm changing. Beyond the range 1400-1600 isn't strange sound.
What can the solution? what have even I change besides that?

Thanks in advance for your replies,
Tomi from Hungary
