Yet another EZL failed on a 3.0 M104 (my parents). I have tried all yards with a 300SL on car-part.com and all the usual yards, no luck. I have sent it away to 4mercedes.com but there is a decent chance that it is fried and unrepairable. I would rather try something before having to pay $1100 for a rebuilt. Has anyone used an aftermarket ignition or tried to get a M103 EZL to work. Who really needs a knock sensor anyway It seems that the M103 option would be the easiest to retrofit, all I need is some spark! The EZL is no longer available from MB either new or rebuilt, and their last price for both was $2,700!!!! Thoughts?
