I have for sale an ABS/ASR module for the 500E or E500. MB part number is 011 545 48 32.
This module was taken out of a 1992 500SEL (W140) but works fine for the 500E and E500. Should also work for 400E and E420 cars that have ASR.
Date of manufacture is February, 1992.
Price is $135 shipped Priority Mail in the USA. That breaks down to $121.40 + $13.60 shipping.
Ideal for long-term owners to have as a spare unit.
