Another benefit of prepaid maintenance. They don't charge more if you have the LSD but they do cover the change.

I do all of my own maintenance so I know it is done right and it is a lot fricken cheaper as well

Mort

Same part # as the fluid I bought to do mine. That is the correct fluid.

JRHolt

Yes you are correct, the part number is: 001989520310.

ECS Tuning sells it at pretty good price

quaife isnt a clutch type differential like the factory performance package one, it's a torsen type. So no need to change fluid any more frequently.

I have a wavetrac
At 2000 miles I may change it
All gears break in and shed some debris

JRHolt

I think you guys are a little confused about this service requirement. The oil change at 2,000 miles is for initial wear for the new LSD Differential clutch plates.

After the initial 2,000 mile oil change then it is changed at every 40,000 miles

If you know how to jack up a car and know how to remove two oil plugs then you can easily do this yourself. If you don't have a clue what any of that is then maybe you should not attempt it

My e46 had the tranny and diff changed at 1200 miles
The lsd was a sealed clutch pack not open to the diff fluid
All gears wear more initially until they mate up
Modern maching minimizes this but can't hurt (other than the wallet) lol
Do it 2000 and not again for 50-60k miles

Maybe 3000

The ring and pinion is already broken in but the wavetrac has a bunch of stufff in it

No, not confused about that. I meant not having to worry about different servicing interval recs versus the ones that I'm now clear on. Once, I mean if, I get a LSD then I'll have to evaluate how that should be properly serviced.

As far as DIY is concerned, I can definitely remove 2 drain plugs. Not sure I want to Mityvac and prewarm and do some of the other stuff that I've seen around the forums that may be required to change oil, diff fluid, etc. Although after I've paid a couple of dealer service bills my attitude may change . I've got about 2/3 of a clue, I guess...

jcfay,

If you plan on owning a Mercedes for a long period of time and want to do more of your own maintenance then investing in a MB DAS Xentry setup so you can diagnose and monitor the systems on your car

I plan on only driving Mercedes from this point on and it is an invaluable tool.

Valvestud

If you don't mind, what all is involved in getting Xentry, and approximate cost?

Thanks,

Joe

JRHolt

Sent you a PM

Mort

JRHolt I would appreciate information on the Xentry system as well.

Thanks, Mort
