Wrong gear oil in differential
I brought my CLS55 (NO 030 package) in for it's first service yesterday 1000 - 3000 mi.
For some reason (incompetence) they changed out the gear oil in the differential with 75w-140. My car is supposed to have 85w-90.
What problems could this cause, if any?
They also scratched the hood, so it's going back on tuesday.
I HATE OTHER PEOPLE TOUCHING MY CARS! DAMN IT!
I'm extremely pissed off right now.

Better Gear Oil!!!
CLS_AMG - Your Dealership did you a favor by using 75W-140 Gear Oil. It is most likely the same Gear Oil that is used in the 030 LSD, which is a superior Gear Oil and it also can be used in "NON-LSD" Diffs. Now the scratch in the Hood is another Issue altogether!! 
Sorry to hear about the Hood damage 
, but the 75W-140 Gear Oil is not a problem.
