$600 - now that's more like it. Has anyone got a link to a supplier - pref one that ships to the UK?
I new Jim (
http://pages.prodigy.net/jforgione/MB_S500.html) had some excellent pages covering ETAs and it seems my low oil pressure issue - now I found his site again - thanks Jim!
Also, it seems like I don't need to remove the manifold to get the ETA out - that's handy ;-)
My father-in-law happens to be a mechanic (has been for over 50 years) so if it's s DIY job then it going to be OK I think.
He recommends that I locate all the parts first then we can review and fit
