88inchthing Posted March 14, 2010 Share Posted March 14, 2010 Hi all The oil light has just started coming on at idle on my 200tdi powered series3. I seem to recall reading somthing on a forum about a core plug that works loose (pressumably on the main oil gallery)? Just wondered if this rings a bell with any one.

Thanks Les,I now recall it was a cam bearing that can move and cause oil pressure to drop. First port of call will be the oil pressure switch as you suggest.
