Mercedes Ignition Module Up for sales is a OEM Mercedes w140 chassis ignition module. It is Mercedes part # 013 545 63 32 (0135456332) . This came out of a 1994 S420, and will work with many other models/years with the M119 engine, but as always your best bet is to match up the part number with the one you are trying to replace. 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. These are usually quite reliable, however they can be easily damaged by voltage spikes caused by improper type spark plugs, very worn spark plugs, or a faulty alternator. If this unit is faulty you will either have a no-start or a random cutting off condition. Thanks for looking!
