Thankfully on the '11 Accord, the filter is vertical directly above the drain plug. Super easy to change....drive up on ramps, pop the drain plug, wait about 2 minutes, drop the filter, button them both back up, and climb up top and refill with oil. Whole process takes about 10 mins.

Not all MB's are simple to change the oil on either. The '83 500SL has the cartridge type oil filter on the bottom of the engine in a difficult position to reach, so not only is it awkward to get to, but it makes an enormous mess getting it out of there! Thankfully that car isn't driven a whole lot, so it doesn't need oil that often.

No injector leaking noted on my early production '05. I also do periodic inspections.

Just changed out broken rear springs (inspect yours carefully), installed new Bilstein rear shocks (upgraded B6) and new set of Michelin Primier AS and alignment by Mercedes dealer. Vehicle still my favorite road car with 120k miles! Hoping it keeps on trucking!

How the heck do/did rear springs break??

I always upgrade Bilstein shocks to the HD ones, when necessary to change out due to miles.

FWIW: Auto Zone HD Bilsteins for my 83 300SD were a lot cheaper than buying from the MB dealership, and were eligible for free replacements, when they started leaking fluid. I got one free replacement set all (4) for my SD that I racked up 305K miles on when I was doing heavy road miles in the 1990s.

I'm probably going to revert back to the steel belted Sears Roadhandlers (if they still have/offer them) when my CDI needs new tires. I started running them on my '83 300SD, 20 years ago. Michelins are pricey!

The rear springs are a known issue on the CDI...not sure why. Mine were replaced at 108k mostly highway miles.

Symptoms?

At what level top to bottom do they break?

Was it a DIY job?

Part resource for springs and cost of springs and labor?

No idea....done by PO. But I do know that springs are cheap from dealer.
