Thanks Mel, you are right about this, but it seems its not the only cause for "tappet" noise..
The dealer repaired the variator at first visit (replaced a spring), but it didnt work. At a second visit they replaced the variator on warranty. Guess what.. it dint work of course
At a third visit they found out (as Hoygaard had also said to me) that the manifold gasket had a leak. "Ok, i said, no problem, lets change it".
Well they change it and the ticking noise disappeared. My happiness lasted one week only... the noise came back..
At the 13.578th visit they replaced the gasket again (putted some glue also), and they said that it wont happen again.
Well guess what... i hear a ticking noise at cold start up every morning..
Thanx anyway wink
