I've been contemplating doing this too. Somewhere along the way I was told the part number is 000 466 18 80.
I'd appreciate hearing your progress and process for this repair. Good luck.

That O-ring is less that $5.00 from the dealer. R&R would be about 30 minutes. I used a turkey baster to remove the fluid from the reservoir, undo 2 retaining bolts ( if I remenber correctly), remove hose, pull the reservoir forward, clean reservoir and R&R O-ring. Then reverse the process. Cleaning took most of the time doing this procedure.

Do the new ML's use the same POS power steering system? My 06 ML350 just had power steering warranty repair done at 38K miles (leaking reservoir).

What I have found..
I don't know about the W164 steering compared to the W163 steering, sorry.
On the "o-ring" replacemewnt - most DIY's also chose to order a new "c-ring" which is a steel clip ring which holds the reservoir. First, good to have a spare c-ring in case you drop the original during removal. 2nd, most expereince3d MB mechanics replace the c-ring since the stampled steeel part will lose some of its original holiding strength with a couple of removals.
Also , you will need MB "power steering oil" (about USD$9 per qt) to top off after replacement. Takes about .75 of a qt, most people buy 2 qts to have some in the garage. Best to use original MB p/s/ oil as not to mix different typer fluids in the power steering system.
If you are also replacing the reservoir, you can use the color caps from the new reservoir to cap off the old fittings on the old reservoir to help keep the mess factor down.
Keep the beat !

Removing the C ring
I found the easiest way to remove the C ring was with a small hook.
Just slide the hook into the ring on the side nearest the left fender and pull straight towards the fender.

Guys, also check the power steering fluid cooler hoses on the side of the radiator on the drivers side.
Usually one or both of them have walked outward and can pop off any time causing you to lose all the fluid at once.
Simply pushing the hose back on flush and tightening the clamp will do, but sometimes the hose itself is deteriorated and all "gummy".
In this case, I usually cut a bit of the bad portion off and reattach.
Do not cut too much off because there is not alot of length to work with.
Sometimes the cooler portion of the radiator plugs up and causes the hoses to pop off regularly.
Some techs can gently blow compressed air into the coolers from inlet to outlet and blow a slurry of debris out, but it is not recommended.
I have also seen some where the cooler ports on the radiator are purposely blocked off, and an auxillary p/s cooler is installed.

Would someone please tell me what the tool you used to remove that "retainer bolt" (1) that attaches the reservoir to the pump? I can't find the tool that matches the weird-looking bolt on it. Mine is 2003 ML320. Thank you!!!
