I just bought this car ,And of corse we all analise something new to death. When the car sits for about 8 hours on a cold day say below 50 .The valves sound like they knock for a second or two.I asked the Mercedes dealer and the said it was some kind of purge valve? , And not to worry about it.

Has anyone else had this problem?

Yeah, the dealer has not steered you wrong. I've seen this hundreds of times in my shop. The purge valves are quite easily mistaken for lifter tick, but it is indeed normal operation.
