e46 330d issue

[Jeppe777]

Loosing lots of water when driving, however when parked no loss.
Cant see where the water leak is coming from.

Noticed black/white smoke under acceleration - no misfire or power loss.

Checked the oil level and its fine.

This should be very interesting... Hope you get your machine sorted out soon. This sounds very strange though

Check waterpump and thermostat housing

Check under intake manifold. Drive the car for about 10km to get cooling system up to temp. Then leave motor idling and look for the leak.
