I have a 1991 420SEL. Can anyone tell me if all fuel injection control units for the 420SELs are interchangable?

Thanks in advance,

Bob

i cannot tell you for sure, but if you give me the module numbers, old and new and the vin of the car you are going to put it in i can tell you, it is likely the module may have been updated and that is why the numbers are different,

Hi,
Thanks for the rapid response. I have a back up unit,
MB part # 004 515 39 32 and Bosch part # 0 280 800 170. The car I want to install it in is Vin WDBCA35E1MA594502.

Bob

the one that is in your car should be 009-545-45-32 that one was used from 1988 and newer. is for california models only

the 004-515-39-32 was used only up to end of model year 1987.
the unit you have may work but is not correct it is for federal and california models

Ray,
Great solid information. Thanks for your time.

Bob

glad i was able to help
