boyt Posted October 3, 2010 Share Posted October 3, 2010 hello i have a 200tdi and 300tdi, if left for four hours or more the 300 oil light will stay on for 3-4secs at start up, were as the 200 goes off strait away, changed oil and filter, changed oil pressure switch, when warmed up its fine, no engine noises, before i rip the engine apart has anyone else had this issue, have ordered a oil pressure gauge as we dont have one at work (only mercedes main dealer!)

Tetsu0san Posted October 4, 2010 Share Posted October 4, 2010 As long as the light goes off and stays off then I wouldn't worry about it. It could be a worn oil pump but if the light goes out, even after a little bit of time then there must be enough oil pressue in there. There are no big oil leaks are there? And the oil level is OK? You could service it and change the filter and see if that improves, but it doesn't sound like anything to worry about. Quote Link to comment Share on other sites More sharing options...

Range Rover Blues Posted October 4, 2010 Share Posted October 4, 2010 Before you rip it apart see what reading you get from the pressure guage with the engine hot. It the pressure is ok then don't worry about it for now just keep an eye on it. To give you peace of mind you could use an oil with a stabliiser in it or Magnatec to give better protection at startup. Quote Link to comment Share on other sites More sharing options...

cackshifter Posted October 8, 2010 Share Posted October 8, 2010 Oil too thick can cause delay extinguishing the light 10/40 was much quicker than 15/40 in mine. Nigel Quote Link to comment Share on other sites More sharing options...

mayur Posted October 13, 2010 Share Posted October 13, 2010 hi i have this with my discovery everytime i start first thing in the morning i belive that the oil goes back through the turbo oil feed, when i get a chance i will fit a one way valve on the feed pipe and see if it stops the problem Quote Link to comment Share on other sites More sharing options...
