I have to question why this should sound (even in the wildest imagination) anything like a muffled diesel?
It is not and has never been associated with Mercedes Diesels.
The fact that it changes when in neutral indicates the ticking merely is directly associated with RPM.
BMW started out building air planes so should a BMW sound like one of their old fighter planes???
Yes, I do ***** and rant alot (so I have been told) but where does some of this logic or should I say LACK of logic come from?
Jake, I hope this helps you to realize it is to your benefit to accept automobile advice from some members with a grain of salt.
