So my 2006 E 350 I purchased with around 165k about 31/2 years ago. At that time the CEL was not on and I figured that I had managed to escape the dreaded balance shaft issue. At around 185k the light came on and the codeP0016/P0017 made it official. I now have 222k, drive it every day approx 90+ miles round trip to work with no performance issues. My sliding rear cover has stopped, auto backup mirror adjustment is intermittent, rear hatch struts are dead, a slow leak down on my left rear airbag, and I have developed an unusual tread wear pattern on the right rear tire that hollows out the inside corner and causes the tread to separate in several locations. The tire shop said that that alignment was good but I have had to replace this tire twice this year. I think I have figured out a way to change the balance shaft without removing the engine. I plan on tackling that this summer. I still get 22/23 mpg on highway and love the hauling cap.

So you've driven 37,000 miles with a bad balance shaft? Any consequences? Worsened over time? When mine went the vibration was barely noticeable but I had it repaired within a hundred miles so I didn't have much experience driving it like that.

No problems. It is my daily driver 90% highway. Acceleration and cruising and no vibes. I just have to get a waiver for my tags since my county in North Carolina requires no CEL. I have done a ton of research, watched numerous how to videos on changing that thing, but I do not have a garage so when I decide to tackle this project it will be truly shade-tree. I have never seen anyone change it without removing the engine.

Mine can get 29-30 in the right conditions and average is 26 on the hwy

That is awesome Shack. Is your Merc a 4Matic?

'07 E350, 170k miles. But not without a new intake manifold at 160k miles and a new right side cylinder head at 107k miles.
Otherwise, very tight and nice drive.

No, 2006 sedan version of yours

103K miles
 

Bought used in 2009 at 29K, now has 103K. Bought extended warranty but cancelled it when factory warranty expired due to lack of problems.

70K Yaw sensor failed, Stealer wanted $2K to fix, reduced to $1250 when I declined due to cost! Never went back to him.

81K Evaporator temp sensor replacement solved AC freezing up on long trips. DIY

86K AC compressor replaced

< 90K Tumble flap arm failed but I chose to ignore this as they are stuck open, car passes emmissions, and mileage has not suffered.

96K. Bad oil leak from left cam plugs and right side breather

Replaced SBC battery at 57K and 99K miles with regular non-AGM motorcylce battery.

Change Mobil 1 0W40 oil (DIY) usually once at one year at ~6 to7K miles, or 10K whichever comes first. Tranny service every 39K miles.

About to replace voltage regulator to get rid of occasional low voltage warning, battery is fine.

Driven cross country 3 times, about to do it again this August. Great road car!

109K and no mention of motor mounts being replaced? Or any suspension arms, rubber bushings torn or worn out? Struts haven't been replaced? That is amazing!

i have 180+ on the e500 estate. just got done doing a LOF and state inspeciton. will need to do rear pads and rotors soon(er) and possibly valve cover gaskets in near future as well.

145k and running strong (sort of)
 

The car runs great, absolutely no reason to turn it in. It runs well until it does. When something goes wrong it makes me panic (primarily due to towing and stealership partying on me).
Brake fluid flush once (stealer)
Steering fluid flush once (stealer)
Rear differential fluid once (stealer)
Central computer module (stealer, in fact it was alternator that I did myself)

Oil change every 5000 miles (diy)

Following are DIY with parts from FCP Euro

Three brake pad sets (two rear)
Transmission oil at 106k, 133k and then again 133k due to leak
Lower balljoints twice
Engine and transmission mounts twice
Two front suspensions
Two rear suspensions
Two rear struts
Valve cover resealing
Alternator once (dont do voltage regulator alone, does not last and results in towing)
Coolant flush at 110k and 120k (once at stealership and once myself in 10k after stealership work)
Thermostat (BorgWarner, preventive)
Coolant temp sensor (preventive, bosch I think)
4th set of tires (always go for name brand tires, dont repeat my mistake)
Thurst arm twice (will do this again with Lemforder)
Upper ball joints (once)
Lower control arm (preventive, with TRW from FCP)
Tie rods inner and outer (preventive, Lemforder)
Front sway bar link
Crankshaft position sensor
Idler pulley (preventive)
Tensioner (preventive, just pulley but put back the original, will do this again with INA)
All rotors (preventive)
Front wheel bearings (one side went bad again, but FCP use-abuse-return warranty covered it)
Ambient temp sensor
Now on 3rd battery. First battery lasted 11 years, second only 3 years (all MB batteries)
Secondary battery once
Air filter twice
Cabin air filter (once, I doubt it requires replacement, after 14 years the original one looked like new)
Cleaned throttled body once
Cleaned MAF once

I was getting 23 mpg doing 80 mph, after fixing vibration issues related to wheel bearing I am now getting 26.5 (doing 80 mph). I remember I was getting 28.5 doing 70 mph but no longer have the patience to do 70 mph

2003 w211 e500 2007,000K gas .... no major engine problems, mostly front suspension joints and bushing replacement

141,000 on my 2003 E320 I have owned it for 9 months, was given the car by an older couple that was moving and did not want to make it roadworthy again.

I have replaced the:
Battery, aux battery, battery control module, battery relay, alternator, cup holder, right rear door glass (broken), fuel filter, visors, front brake pads, fixed trunk leak, cleaned carpets and replaced heater switching valve.

Next it needs a transmission service, tune up, brake flush, cooling system flush, rear axle service, oil change and a headliner. I have found no major problems with the car and try to drive it at least 250 miles a week.

104,000 miles on my 2008 E350 4Matic. I drive about 5-6000 miles a year.

-Oil changes (DIY with vacuum extractor)
-Brake service including fluid replacement and greasing calipers
-Air filters, cabin filter
-Spark plugs at 100k
-Set of summer and winter tires (Michelin Pilot Sport AS3+, Bridgestone Blizzak WS80)
-Upgraded to SL55 wheels for summer, stock wheels for winter
-Replaced drivers seat foam
-Full detail and compound/polish every spring

Only outstanding issue is the rear pano roof shade, it seems to have come detached from the motor? and won't open. Have to drop the headliner to fix it, but if I've been putting it off while considering upgrading to the alcantara headliner found in the E63 and designo cars. Front bumper could also use a respray.

2007 E 550
 

2007 E 550 (gas, not 4 matic), bought well kept at 34,000. Now 132,000. Keyless Go just stopped working 4 weeks ago, but otherwise nothing but well known brushings, suspension arms/joints, motor mounts-- costs not bad as either warranty at dealer or great local indie Goose here in SA. Considered selling cuz bought new cabriolet but keeping to see if can reach almost 300,00 mom's SLE reached. I am looking into upgrade of command audio as like functionality of cabriolet's system & rear view camera.

If it is just the start button there is a common problem where the wire breaks at the base of the shift lever.

Search the fix.

Thanks
 

Thanks. Done so & unfortunately (fortunately?) not just start button. Great info on issue but none worked. Probably end up paying dealer unless too crazy at which time will do as did in good ole days w first 8 Benz & use key.

2009 w211 153000miles timing chain tensioner problems

What is your symptom?

Do you DIY the transmission service? Is the transmission service a full flush (10+ qts) or a pan drain and refill?

also wondering about this

i am at 150,000 miles, pot holes in my area are causing me to have to replace wheels and suspension components, but other wise its been great.

I have replaced the intake manifold, various intake solenoids, the oil breather, and the transmission conductor plate.

I have also had to fix a hose on my sunroof drain.

Next project is CV Boot replacement

I do my own oil service, but without a lift, trannys are a lot messier on my garage floor so I let the local Indie shop do it. Drop the pan, replace the fluid lost and replace the filter. Not a flush.

mileage 185590 2005 e500 estate

recently had to replace the main battery (lasted 5 years), New tires all around, and alignment. Also did a LOF while at it.
