190e differential
 

Hi,
I have a 1986 190e 2.3 USA. I have a owners manual that I purchased separate from the car and it covers several models. In the capacities section of the manual there is reference to both a standard rear axle and a rear axle with automatic locking differential (ASD).
Can anybody tell me if I have the standard type of rear axle or the auto locking type or how I may tell the difference? It matters in what type of oil I put in the differential. My differential part number is:201 351 14 01.
Thanks in advance.

The VIN number is: WDBDA24D2CF252801
Thanks again.

It would help whomever may try to assist you, if you would post your VIN#.
