Rear Differential Service- Advice Needed
The owner's manual doesn't list any recommendations on changing the rear differential fluid on the rear drive C class.
The dealer has recommended it the last couple times I have been in but I have deferred.
Couple of questions:
How often, if ever, do you guys change your differential fluid on your non 4Matics?
Does the OEM plug have a magnet? If not, I will buy a Dimple brand plug before I do it.

In general, will the dealer use an aftermarket plug if I decide to ask them to perform the change?

I change mine every year along with the tranny fluid. Doesn't cost much for this piece of mind. I run Fuchs 4134 for the tranny and castrol 75w90 before but Fuchs diff oil now. We reuse the hardware for the rear diff after cleaning it.

Every year? Wow, that seems like a little bit of overkill...but since MB doesn't give guidance, I suppose it's whatever makes you comfortable.
Does Glyn or any of our other genius gearheads have any input?
At least, does anyone know if the OEM plug has a magnet?

I go more off mileage than time. I caught the mention of changing it with the tranny fluid which I do as well, but missed the 'every year' part. Every 30k or so is comfortable for me. Keeping in mind these are synthetic fluids. This may help...
