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.
This unit was removed from a recent crash damaged car that still ran fine. It is in good shape. A defective unit can cause a whole host of problems with these cars, including random misfire, no-start, and intermittent no-spark on one or more cylinders. Rumor has it that these units are generally fairly reliable, however they can be damaged if they see excess voltage (from a bad voltage regulator) or, apparently if you install non OEM spark plugs, as they do not like anything but the resistance values provided by OEM plugs.
I will give a DOA warranty with this. It will work on arrival, however I do not warranty these for anything beyond that.
