Hi! I have a 1994 e250 diesel (w124) automatic UK model which i need to replace the worn differential. I,am looking for a second hand diff but can only find ones from petrol models with low mileage. Can someone tell me if any other versions have the same diff such as 200, 220, 280, 300, 300d etc. The serial number on mine is R201 351 16 08 on the back and 201 351 04 05 on the side - thanks, steve.
