I have a 200tdi here, the oil pressure warning light comes at idle..
Engine runs perfect and there's enough oil in it. Could this just be the sender, do they often break?
It would be worth checking the oil pressure with a manual gauge.
Most likely problem is that the cam bearings have spun in the block causing low oil pressure on idle (ive had this happen). Slip the engine out and send it to turner engineering or someone alike for new cam bearings and machining. Probably not going to be cheap though
