Go to dealer. Leave it overnight. Run it with heat on, and run another car from dealer at the same time. This will show dealer that yours is not working right.

Nothing is "happening with Mercedes". At the end of the day, these vehicles are still machines. Things can go wrong and there will be times that these THINGS do not operate 100% perfectly. Similarly, there can be issues or problems with iPhones, refrigerators, home air conditioning systems, etc. There will also be times that dealer service centers have some trouble getting to the bottom of certain issues and fixing them right away.
But I'd wager that for every 1 vehicle with some kind of defect or early mechanical/electrical/operational issue, there are probably 10,000 that work perfectly with virtually no issues within the first several years of ownership. The inconvenience and annoyance of dealing with an early issue is unfortunate. The bright side is that you are covered under warranty, so any repairs that may be necessary will come at no cost you.

1) If your engine temp gauge is showing normal operating temps (e.g. 1/2-3/4) then, as per the circuit diagram you can see that your heater circuit for the interior will also be able to draw from that same source - i.e. the collector (5) and therefore you should have warm air. If your engine is cold you won't have warm air inside either.
2) Unless the coolant pump is running you won't get warm air either because there is no flow to the collector (5). As you can see, that condition can last more than 8 minutes. That could be the case why you think it takes 10 minutes for the heater to start working. That to me sounds like the most logical explanation given what you're describing.

Well, ... there's at least two things you can consider:
1) If your engine temp gauge is showing normal operating temps (e.g. 1/2-3/4) then, as per the circuit diagram you can see that your heater circuit for the interior will also be able to draw from that same source - i.e. the collector (5) and therefore you should have warm air. If your engine is cold you won't have warm air inside either.
2) Unless the coolant pump is running you won't get warm air either because there is no flow to the collector (5). As you can see, that condition can last more than 8 minutes. That could be the case why you think it takes 10 minutes for the heater to start working. That to me sounds like the most logical explanation given what you're describing.

Sounds logical but too technical for me. I will study it carefully to rebate dealer. Thanks!!
