You're not very clear in title or description.

Do I take it that you mean that you have self levelling suspension and that you're finding engine oil in it? If so what steps have you made to confirm this?
If not then a clearer description is needed.

Its impossible for this to happen

Sounds most odd, but something similar has been reported in the states

I am confused, I thought the zh-m would be the pump lubricant? or does the pump also use engine oil with a seal between the two fluids?

Not so, if its the suspension hydraulics. the self leveling pump, driven by the camshaft has a small seal which fails and engine oil is sucked into the leveling sytem. remove pump and replace seal if its still available seperately.

Post up a chassis number, and I will search for part numbers.

Hi This sounds like the route of the problem, Thanks

hi Richard
The chassis No is WDB1240832F153672 The parts I think I need are the seal and perhaps the sealing ring to the pump on the self levelling suspention hydraulic pump.
