Looking for part number.

Hi guys,
I have a 2007 ml320 with 140,000 miles and absolute love it.
The o-ring for my turbo is bad and I can't find part number. It's the one between the charge tube and the resonator. The tube comes out of the turbo, turns down and goes into a black thing that's bolted to the front of engine. There is a o-ring in there.
If anyone has replaced it and knows the number I would appear it.

Suggestions:

- download WIS/EPC from eBay for around $6
- look at mercedesbenzstarparts.com or similar
- visit your local dealer and ask them to source the part

Thank you for the reply. I have Wis and have spend time looking. I found the charge tube but it only has that part. I can't find the resonator or o-ring. I'm not near a dealer. I will try the online you suggested.

I was looking for the o ring that goes into the tube near #40. It took the Mercedes parts guy and a tech 20 minutes to find it. I now have 2 on order. Thank you for taking the time to help me.

I have a star system, still learning it but when I search that part number in WIS is says not found. I ordered 2. Hopefully It fits.

You must search for part numbers in EPC, not WIS.

Ok. Thank you very much. Now I can see if there is anything else I should change at the same time.
