Coolant Leak behind dashboard

Hello together,

I`m new and I am from Germany, so before I start writing i want to say sorry for my bad english, and for all the mistakes i`ll write.

In the title you see my Problem, i have a coolant leak behind the Dashboard.

The Problem is, I don't know how I can remove it (Dashboard) on my own.

I will give you an Explanation about what happend or what kind of Problem I have.
While driving, in a Moment water vapor came out of ventilation.
I thought its an air conditioning Problem, so I tried again and I turned of the AC.
But my car is still totally wet and all glases are cloud up.

So there must be a constant Probleme with the Ventilation and there must be a leak.

Is anyone out there who had the same Problem and who can help me?

I would be very greatful for any help.

greets Benny

Take a look at some of the diagrams in this link.You English is great.

I would guess you have a leak in in one of the connections or the heater core.

You get to most of these heating parts from under hood. It is a lot of work to open up everything to get to the pipes but it is not difficult. The online BMW repair manual is no longer available for me to show you instructions to get to the heating pipes but if you purchase a copy of the BMW TIS from eBay there are instructions there. The TIS is the official BMW shop repair manual available on DVD and it comes with many language options, including German.
