I recently blew up my C43 differential and am looking for a replacement. I can not source one at all! I've looked all over the Internet and have had no luck. What differential can I substitute in from another model to make my car run again? I'm thinking maybe the cl430 or any other 430 since it's the same engine basically?

TL;DR: What differentials can the W202 C43 use from other models

The only one which plug & play with "W202 C43" is "R170 Slk32" diff.,,

but if you want to replace the gear & pinion, you can go with "W208 Clk320/W211 E320/W220 S350-S430 4matic-S500 4-matic"...

Damn so only the SLK32 will bolt right up? It has the 3.07 gear ratio?

Yeah sure, "R170 Slk32" got (3.07:1) Ratio, and direct bolt-on..

I just thought of the SRT-6! Doesn't that share a differential with the Slk32 also!?

Replaced my old differential with a 2002 SLK32 diff. The car is back on the road, good as new!

did slk32 diff have 3 finger or 4 finger flange?
maybe MB upgraded bearings in the slk32 diff coz having more HP than c43?

Any software retune required for the SLK32 diff?

Slk32 is Exactly the same with C43 one, NO any difference..

No need to reprogram it, it's PLUG & PLAY..
