Hi all...help please?....My 1997 c180 , vin WDB2020 182F 644 850, has a faulty fuel sender unit. (reads not empty when it is empty etc) . I got a quote for $800AUD (australia). The auto electrician said he'd heard from Merc dealers , that this was a common problem, due to the connections being "gold"?(I may have got that wrong) and reacting badly to our fuel in Australia.

Do you know anything about this? Thanks, Rossl
