2007 1.8 Petrol C180 Kompressor ( Coolant in Oil )

[manicstereo]

Is there any common issues on the 2007 1.8 petrol c180 kompressor causing coolant to get into the oil, such as oil cooler etc?

Welcome.

No, it's not a typical fault on the M271 engine.

But both a leaking heat exchanger (oil cooler) or a leaking head gasket are good guesses.

BTW, if driving mostly short distances in cold weather, it's common for condensation to accumulate at the top of the engine e.g. under the oil fillet gap - it forms a 'mayonnaise' looking residue.This is normal and the water content will evaporate once the oil reaches working temperature. If, however, the 'mayonnaise' residue is spotted in the engine's Lower parts - e.g. on the dipstick - than this isn't good, and it means that there's water in the oil.
