Mercedes Ignition Module Up for sales is a OEM Mercedes 126 / 116 / 123 chassis ignition module. Bosch part number 0 227 100 042

My list shows this fits many 380SE 380SEL 500SE 500SEL 500SEC 380SEL models. however it came out of a recent crash damaged 230E Euro model, so it must fit those too. It's probably going to be correct for 280SE 280SEL's as well. Clearly you'd want to check your original part number. It is Bosch part # 0 227 100 042 / (0227100042) M-B part number (0025452632) 002 545 26 32  I only sell the OEM units, never aftermarket so they are the same quality as your original. This module lists for over $2000 from MBUSA, this is listed at merely a fraction of the dealer price. This again is a good used Genuine unit, not cheap aftermarket.  Thanks for looking!
