Who has over 100,000 miles on their gasoline W211?




The Balance shaft is a known problem, but the transmission is likely to be a time rather then mileage issue, maybe made worse by all the sitting.
are many many documented issues with the 722.9 overly complicated trans. Did I mention its been garaged and in dry socal all its life?
And MB should have covered 100% of the balance shaft issue, they said I was lucky to get 15% covered.

December of 2012 over 5 million 722.9's manufactured. I'd have to say it's not that bad of a transmission. haha
And if it was in fact a poor design MB would have re-designed or applied a different trans when "direct select" became about.....
I think chrysler and a few others use this trans as well.....
I like the 5 speeds but fuel economy is very poor.

Major problems = none
Minor things = recently had oil cooler and oil separator seals replaced due to oil leaks.
Mntce. History = Maintained according to "the book", except oil changes. Oil/filter changed each 5K miles, and oil sample tested annually...all results = Excellent.

PS: For the past 35 years, our primary vehicle has been a luxury class car; i.e., 3 Jaguars w/mixed results, a BMW 740 iL...a terrific car, a M-B 320 CLK Cabrio...another terrific car, and now our '09 E 350...may be the Best of the Bunch. Presently, we intend to keep the E 350 for a couple more years, and then maybe find a pristine 2014-15 ML 350 suv.

288K+ and counting- pls see the images in my album
(I am adding 175 miles per day Ubering in DTSF)
- No known or reported a major mechanical issue.
- Replaced the radiator a year and 1/2 ago.
* the previous owner who happened to be my uncle has been driving MB since the 70's and although the car has a high mileage he did a very good job in maintaining the car, he does oil change every 8k, replace transmission fluid every 12 to 18 months, lube and grease all the bushing on the suspension every year, as well as checking and adding oil in the differential box.
*brake fluid, coolant and power steering fluid, and engine oil, are being checked regularly.
As of today, the car is running smoothly the engine is quiet and with good compression. Transmission is shifting properly no fluid leaks. The suspension is making some noise every time I hit a bump. There are minor scratches and some dings on the body, all the leather, felt, dashboards, and woods, in the interior are all intact and well-taken care as well.

The Best of Mercedes & AMG







Current mileage = 164,000 miles
Major problems: = None, but see below (steering rack)
Maintenance History = This week I replaced all rear suspension links and bushings (except subframe bushings), rear brakes, had brake fluid flush done, replaced steering rack due to 2 leaks on it, necessarily had PS fluid flush done.
Last year I had front suspension components replaced, replaced intake manifold (due to butterfly breakage), knock sensors, cam magnets , another variety of sensors and seals & throttle body (I think I ruined it cleaning with throttle body cleaner when I replaced the intake manifold).
~2 yrs ago I replaced shocks & struts, had fuel tank assembly replaced under warranty (due to issue with gas smell after filling tank).
Car runs absolutely great.
To those with transmission issues, I've done some research that suggests that the trans fluid MUST be changed religiously every 39,000-40,000 miles or transmission failure is pretty much a given

100k - water pump, passenger side PCV gasket reseal, aux battery, main battery. Will do plugs soon.
80-90k - driver side lower control arm, transmission mount
Other than this, normal ATF flush + ATF filter, air+cabin filter, oil filter changes
at around 90K=new battery, and replaced some leaking oil seals on the topside of engine; replaced MB-Tex on driver's seat bolster...had to replace again around 110K.
At 100K, repaired electric trunk wiring harness...typical.
117,000+miles now, and car runs great...a well built car for sure.
Complaints?
I don't like the 18" AMG wheels...too easy to scuff...wish it had the OEM 17s", but the AMG wheels look cool.

Major issues: Water pump, Fuel pump, Serpentine Belt, Air springs, Drive shaft and Transmission. (tranny was replaced with a used one @ 140K however that one is starting to misbehave now as well. I have a live time warranty on it so I'm not too concerned, yet).
Minor issues: Too numerous to list.
We bought this car used with 130K on it as a H.S. car for our daughter at an auction. In hindsight not very well bought and should've spend a couple of grand more for a well sorted example as I don't think the previous owner took very good care of it. I'm well aware of the "sunk cost" fallacy, but at this point it's the devil we know, That and paying for college is draining our budget faster than we can save up for something more reliable. ;(
Cam seals needed replaced (was leaking oil @ ~120k m)
Panoramic sunroof motor died (once under warranty, again out of warranty at around 130k m)
Airmatic strut failure as expected
Thermostat died that resides in the engine coolant reservoir.
So nothing major in my opinion, though I absolutely hate airmatic. I've done some basic preventative maintenance, for example, changing the rear diff fluid, changing oil/filter and fluids on schedule, and replacing the serpentine belt and associated pulleys/idlers at 130k. That's honestly about all I've done other than wearables (brakes/tires) and the car still runs great.
