I have for sale an E-GAS module, part number 140 545 15 32. This is the computer that controls the ETA.
This computer was taken from a 1992 W140 500SEL sedan. It will work in the 500E and E500 models, but the car will not have cruise control functionality.
Ideal as a spare/emergency unit.
Price is $100 shipped via US Priority Mail in the US. That equates to $86.40 for the unit, plus $13.60 for shipping.
