I have an astra sri and i have an intermitant issue with my car currently.
The issue i have is sometimes on startup i have a grind and clunk on start up. Back in Oct 2007 i had the fly wheel changed due to this noise i am experianceing currently. Since this was done i have had issues with 1st gear and reverse again clunking intermitantly.

The car has been back into vauxhall 8 times with this issue and is currently back in the garage. Then excuse thay give me is they can't find the problem i am having.

This is very frustrating for me , can anybody ive any advice concerning my issue i have.
