Highest Milieage ??Who has the Highest Mileage on the RClass
Rear air bags -- do they go bad on these cars, or why replace them? I'm also curious about the the Command replacement - what are you replacing with (and why)?
My car -- 08 R350 -- now has 133k. As mentioned in a previous post, not driving much anymore. But now right rear sags after a few days of sitting... air spring was replaced 3 or 4 yrs ago. Feels like it's deflating too slow to be the air spring again, might be a fitting at the valve block or the valve block itself... Don't know. I suspect we wouldn't notice it if it was a daily driver. Again, in my experience these cars are not trouble free. Still surprised at 191k w/o issues!

Wish it was an R63, but happy with the R320. It still turns heads - nobody knows what it is.
Only major issue was torque converter about 20K miles ago - instead of replacing it ($$$), I found a guy on eBay who rebuilds TC's for $250, so with my indy mechanic's labor total cost including shipping to/from Chicago was less than $1000. Smooth as glass now.
And I'll add this tangent in case anyone in this thread has had similar experience (God knows I've searched the forum), struggling with the rear liftgate; right now it opens normally, but the red lighted button to close it doesn't light up and doesn't do anything, and when I try to close it with the key fob or driver's door button it stops halfway. When I close it manually and drive off the hatch open warning light comes on even though it's latched tight. Also get a message, maybe not related but happened the same time the failure started, that the left license plate light is out when it isn't. I've got the iCarSoft OBD reader but it doesn't show any codes, though it does show a rear SAM fault. Don't want to replace that without more evidence, probably need a STAR reader. Sorry for the tangent.
Possible candidates for replacement for the liftgate situation:
- actuators/motors
- latch
- button
- control module
- rear SAM water infiltration, this is not uncommon on W/X164 vehicles
I have the same issue and did you get to know what was the cause and if any resolution.
Thanks.
