The whole connector was updated with new seals. Visit your friendly MB
dealer for the new part. #203 540 00 53 and 4 qts of fluid #001 989 21 03 10
Ask dealer for assistance. Very very common problem.

Think the dealer is expensive? Do you know how much it costs to train a dealer tech? Or buy the required MB special tools to have on hand?
