Help. I have just had my radiator and oil cooler replaced. Before this my oil pressure gauge was functioning properly - now the needle won't move at all. The engine is running fine and there are no leaks. The garage can't determine what the problem is. As I'm not happy with driving the car without the gauge giving a reading could someone give an idea of what could be wrong?

The oil pressure sensor switch (on the side of the engine near the stainless steel turbo oil feed line) may have one or two of the electrical leads disconnected.

Clean these leads of any oxidation (if required). A replacement sender unit is comparitively cheap plus it is easy to replace. But try the cleaning of the connections before you buy a new sendor.

Solve the oxidation on the contacts, in the future, with dialectric grease (i.e. from a points set . . . also sold for sparkplug leads and sparkplug tips).
diaelectric grease is expensive, small and hard-to-find ($5.00 for a 10 mL tube). Or buy petroleum jelly -cheap and easily found- and $1.75 for maybe 1 pound of it.
