So far I've got about 30,000kms (18,600miles) on them. They still look as good as new.

What are your thoughts on them?
I put them on mine because I was paying a lot for tires and only getting around 25,000 out of them and thought what's the point. My tire guy recommended I try the Sailun. I have been able to get almost 40,000 out of them so far. I will replace them with the same soon, I just wish they were a little quieter.

I find them a little shaky at highway speed, but they may just need to be rebalanced. I'm assuming you're speaking in miles? How much tread do you have left?

Yes, miles. They are down to the wear bars. Mine were shaky at first and I had to go back and have them balanced again.

I would have expected them to last longer than that. You must be a crazy driver

I thought that was a lot? I've never heard of anyone getting more than 30,000 out of tires on a R.

I got 120,000kms on a set of BFG's on my old ML320. I always expect 80-100,000kms on a set of good SUV tires.

Those BFG's still had a lot of tread, they were just out of round.

Poor acceleration and little power at highway speed. No CEL, but when scanning with the iCarSoft it showed a 2510-001 code. It felt like the turbo wasn't kicking in.

I checked the turbo to see if it was spinning freely - no noise and good movement. Then checked the actuator arm to see if it was sticking at all - no problem there. Then I took off the turbo actuator and opened it up, it looked good inside, but after testing resistance on the terminals and soldered connections, I found one connection was broken. I re-soldered it and put it all back together, and all was good again.

Here's the culprit:

Wow!!! Pretty impressive! Way beyond my comfort zone or level of competence. Too bad you're not in Montreal. I'd sure as hell learn a lot from you. Thanks for the insight!

Cheers

It sounds like a big deal, but it's not really. Experience and internet searches can solve 99% of problems.

Had the timing chain, pulse wheels, chain tensioner and plugs replaced at the dealer 2 weeks ago. I bought my 08 R350 with the check engine light on and 1200 & 1208 codes. I replaced the cam magnets and scoped the balance shaft gear and it looked ok, car ran great and no check engine light for a while then it would intermittenly go on/off. I figured it was a stretched chain but had no desire to do it myself, they verified that it was and repalced it. Car runs great and no check engine light. I bought the R cheap enough that having the dealer do the work still has me in the black on cost of ownership. My wife and I both love the hell out of the R. Now to replace front shocks and right muffler. Car has 119k on it now.

Those black wheels look great. I really want to do this.
A BMW hit me in the Lowes Parking lot a couple weeks ago. Not significant damage, but scratched up the wheels real bad. I'm hoping her insurance just gives me a check and I can have a friend strip the wheels and powder coat them flat black..

Had the transmission fluid and filter changed out and drained and put fresh fluid in both diffs since there was no record of this ever having being done in the service records provided with the car. My trans guy said the fluid looked very good and free of any metal shavings and same goes for the diff. I wasn't having any issues just preventive maintenance. Total cost out the door $340.

With almost 70K miles on it runs so good that I haven't spent a penny on it, other than what you would need on any car but it still runs great and goes strong actually. I was a bit hesitant getting an R class at first reading some of the reviews, but I am glad i did because it has been one of the most reliable cars I have ever driven and the drive is so smooth and fun despite the size of the car. The only thing is the low MPG which could have be a non issue had I bought a diesel one but oh well, I am happy with this car.

Been very quiet from me... just hit my 1st anniversary with the car and it's only clocked 6500 miles (give or take)...
I did just do it's Service D (found a new merc indy who's great) and he found a slight noise (not noticeable from cabin , only if you're standing outside right at the engine bay listening) that turns out to be the idler pulley which my warranty covered so thats all good.
And installed chrome step plate for the rear bumper over the weekend. Found it on ebay and i always liked the look but note for anyone, the standard bumper would require 'modifications' to fit them. I dremeled the step plate instead to fit (and broke off all the attachment tabs) and removed a bit off the inner edge but it looks good ... i'll get a couple of photos up ... fixed with 3M double sided.
