Aircon and Heating issues - Something else..

[Mobb]

So after my previous thread I came around to the idea that I need to get the car to a star machine to find out for definite whats wrong with it.

However I have tried to start the heating a few times on the cold mornings of the past few days and every time I start it I hear what sounds like water moving around behind the dash.. It only happens when I try to turn the de-misting functions on..

Anyone have any similar problems / experiences?

Is there a specific problem this relates to?

Happens with my 500 too , despite having flushed the system and bled it every which way , there still seems to be a small amount of residual air in there somewhere .

Heater is nice and toasty now , though .

Getting the R12 aircon converted to R134 is still someway down the list however .

My s320cdi did this when the head gasket had gone. If you turned to max heat (which is what it does I think when the windscreen defrost is set) it would sound like sloshing water.

It would also make this sound every now and then during a journey.

Since Olly did my head gasket (top job) it's never made this sound again.

In my case it was because the exhaust was presurising the cooling system. It's probably something else in your case but is a sign of gases/air in the system.

Ollys a long drive away from me.. but it may have to be done.

Thanks for the comments guys.
