C63 507 204 Does it come Standard with LSD
Seems like lot's of conflicting information re Electronic Limited Slip Differential vs Option code 471 being described as a LSD and also a Rear Axle Differential Lock. I believe these are 2 different things which are being confused. I've seen a MB brochure on this forum for the 507 which also calls the 471 a Limited Slip Differential and no mention of a the word "Lock".
A datapoint from a different 507 for sale. I have looked at the datasheet for a 2015 507 with option 471 and it is called on the datasheet a "ÄMG Rear Axle Differential Lock" which conflicts with the Brochure terminology.
My Question is, Would a Australian delivered 507 from 2014 come standard with a electronic limited slip diff. ie When It does NOT have Option code 471? ie what's the standard?




1) Limited Slip Diff
option 2
2) Option 471, AMG Rear axle Locked Diff.
The marketing literature calls it option 1. Is Option 1 standard on the 507's?

Regardless of whether it was standard or optional, if it left the factory with the LSD it has the 471 code on the build sheet. Obviously some cars may have an aftermarket unit installed, but the only way to check / verify short of disassembling the diff would be to do what @BLKROKT suggested next time your car is up on a hoist. Start the car with the key (not the button - otherwise you won't be able to shut it off in neutral), shut it off in neutral and spin one rear wheel by hand. If the other rear wheel rotates in the same direction, it has an LSD. If it rotates in the opposite direction, it doesn't.

A differential can be one of three types - an OPEN diff (0% lock), a LIMITED SLIP diff (variable lock) - regardless of the type and how it internally functions in order to achieve the torque transfer - and a WELDED diff (100% lock) that always keeps both of the driven wheels spinning at the same rate. Whatever it is that you understand by MLD is a type of a limited slip diff in the same way that beef is a type of meat.

There are many types of differentials and variations, but ALL OF THEM fall into one of the three categories I previously described. There are also many types of meat I like to eat - some of which may be birds like chicken, others like beef, pork and lamb are red meats, and some of which are fish. ALL OF THEM are meat, and the beef, pork and lamb are all RED MEATS despite their differences and variations.
Seeing as that seems too difficult for you to comprehend, I have nothing more to add.
