w211 320CDI 2003 problem please help
 

Hello,

Mercedes Benz W211 E320 CDI 2003

I write to you because I have a very strange problem that we can not find out of any one master.

The problem is the following, there is a strange knocking and I do not know where it comes from.

When the car is cold the problem is not present when the 60+ degrees of warmth is beginning to be heard and over 80 degrees is already clearly heard. The problem occurs only when it presses the throttle and holds 1200 to 2000 rpm. If the accelerator pedal is released, the problem automatically disappears. The car is automatic, and when there is no P problem, when it comes to D or R and the forcing, the rattling is heard. Your car has power, works well and does not smoke. I went through a lot of masters and nobody managed to find the problem. We removed the straps and the problem stood again. Is it possible for the gears or the engine. I'll send you a little video with the sound that's heard. Thanks. Hope you point me to the problem thanks.
