I haven't ever used the Audi tool for the pinch bolt but then I am just a shade
tree mechanic that like working on my car and friends. I have heard that the
tool works but success is dependent on the amount of corrosion. Most people who
attempt to remove the pinch bolt start after having a new replacement available
in case the old one is ruined.

Let us know how it goes.

Hello Tony

Yes I do have a new pinch bolt available, including the nut. What concerned
me was ruining the bolt in the attempt to extract to the point of being
unable to refit the nut, this being the point at which all boats are burnt -
no going back. I always worry to much.

I looked at the top attachment option today and it does look good.

Hello Tony

Yes I do have a new pinch bolt available, including the nut. What concerned
me was ruining the bolt in the attempt to extract to the point of being
unable to refit the nut, this being the point at which all boats are burnt -
no going back. I always worry to much.

I looked at the top attachment option today and it does look good.
