just got this warning, plenty of oil in car, there was a litre of oil too much in till recently, mechanic looked under and said there was a drip of oil on the turbo, could this be the cause , maybe turbo seals or something, he reckons its my turbo seals, but i have full boost, no loss at all, i read it may be the oil pan seals, i need to diagnose it soon so i dont get unneccesary work done, i have to drive to manchester soon and dont want to go till its fixed, the warning light only comes on under braking or at idle, once engine is warm, please help me guy's

 

Most likely the oil pan o-rings and pick up tube o-rings need to be replaced. Also the cross over tube in the pan.

 

might wanna give a look at the oil pressure sending unit as well, those will do it.
