Mercedes Ignition Module Up for sales is a OEM Mercedes W124/w126 chassis ignition module. See the part numbers at the top or in the large picture below. This came out of a 300e and will work with many other models/years with the M103 6cyl 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!
