Hi Guys

I noticed my car was using a little oil about 5 months ago, I kept topping up, I do notice a little oil leaking just under the inlet manifold, I assume the swirl flaps, anyway on the last service i drained the oil and filled new oil and filter, about 4 days later all the oil was gone, like gone, never drip on the floor or anything, just gone, re-filled more and it was fine, on Sunday i did another service and yesterday the oil was gone again, i had to refill today,

where is the oil going to and why when i re-fill again then it stays,
there is no smoke from the exhaust as far as i can see, can it be going into the inlet manifold and burning up, where do i start checking,

thank you

wow... ok, im not sure of diesel BMW's, but i know on a VW when this happens, its usually caused by oil leaking through the turbo seals and ends up going up into the intake via the intercooler. Its quite serious (on a VW at least) as it can cause a run away condition.

if it is the oil seals, then probably means your turbo has to be replaced or recond. whats your mileage btw?

More than likely that its the oil filter housing that's leaking common issue on the E9x platform
