THINGS I DIDN'T KNOW ABOUT MY R CLASS
Great vehicle when it is good but $4K in 60 days is not a good deal. No vehicle should have this many failures in this short of mileage that costs $72K.
I do like the features listed here. Not to many cars are wequipped like that
Heating steering wheel!
My record is as low as 7.8l/100 km in 14-16 C no wind weather at 120 km/hr on 2 hr hauls
As for the realiability, my Bluetech is a bit unreliable and disappointing for a 76 000$ car(with tax and options):
Check engine on broken heating element in Adblue tank 2000$ paid on goodwill by mercedes
Major oil leak on the oil-prestone heat exchanger in the central Vblock cavity. Incompatible silicon rubber gasket. 1500$ paid at 75% by mercedes on goodwill
Leaking cranshaft oil seal (really???crankshaft?) discovered 750$ paid at 75% by mercedes on goodwill
Charge port actuator gone (caused by oil leak from the intake seal) AND intake manifold (flappers supposedly jammed in carbon but they were not) 1200$ paid at 75% by mercedes on goowill
Same incompatible silicon rubber gasket in the intake-turbo inlet
Very painful air filter changes (very bad design) and fragile air filter boxes
Fragile thin plastic intake manifold (was cracked and broken since new)
Now leaky air spring back left (its been tolerable for the past year but now getting annoying)
After 20 000 km, the bottom of both front fenders were on bare rusted steel. Was never on gravel road! bad design! .Mercedes decline to do anything. Bought splash gards that actually protect the fenders and the bottom of the doors as well
All those repairs were required and troubleshooted by me (not dealer) and corroborated by the dealer
The Best of Mercedes & AMG


There is no oil drain plug at the bottom if i recall my checking on this myself a few months back.
All that said, it has been a great car so far and I am very happy with the drive, the space you got and the safety features.
Hidden as it is bloody set quite far back and the only reason i found it was because i opened up the side panel fuse looking to fuse tap (installed a dashcam) and i didn't want wire running down into the centre console, and saw this socket ! ...
So now my dashcam/gps/rearview camera combo (works a treat btw) has power without me having cut up it's power cable or tap into a fuse

(ps.) ran the units power line along roof/window line and then under the rubber trim all the way down into the foot well. nothing showing.
Check out the videos to see the assembly line.
-The new 3.5 motor feels like a V8 while getting more MPG's
- the 2012 doesn't have the active curve bi xenons offered on the previous models.
- the airmativc on the 2012 seems to raise and lower the whole car instead of just the rear....at least that's what it feels like

- the new navigation system tell you current traffic conditions
-and lastly, the optional AMG rims look BAAADAAA$$$!!! on the R

That said, I am going to give MB a call and see what they say. However, I still do not get why I cannot even change the brake light. The upper one, the regular bulb. That makes no sense to me. The manual only shows how to change the reverse light bulb.
Thanks,
G
p.s. I found videos that show how to change the brake light bulb on older R-Classes, but not for a 2012. I guess they change the whole assembly?!
It was mentioned here before that to activate it you need to wash windshield 5 times, not sure if that works too
