my guess is there is a lnown issue with the original SAM module which is why it has been superceded and as Mercedes are expecting a high level of failure they lower the price expecting to move a higher volume nice work as always Dan

[@vehicle-stuff]

I'm not familiar with this type of A class,but in 4 years a vital module to go bad 😔. No wonder the customer stated that out of the blue there was no crank. In some cars at that location it gets hot. So eather there was a bad manufacturing or bad design. Most times bad manufacturing will not be a reason to change the part number of the part. So bad design is my guess. Now to be fare, Mercedes could have decided to use this module in other new vehicles or they might have changed something for the newer facelifts. This could be a reason to redo the design of the module in order to work for all versions of cars. Or they messed up in the first place and do not accept the blame, to be fare .

Outstanding video! On the original module I would trace the red/pink wire from the connector to the IC that controls it. possibly a solid state relay or a mosfet. Next check datasheet, find input and probe the input with a scope. Pretty much the same fault finding technique but on a board level. For the cost of the replacement module it may not be worth it but it gives a closure and satisfies curiosity 😅

Encountered this fault several times why no one could fix it before is puzzling not a hard one to diagnose really but I have found that if you leave the relay in but leave enough of a gap to gain access to the pins of the relay then ground the control pin it resets the SAM & the engine will start again, no new part needed strange but it worked every time & didn’t have a comeback. What no one failed to notice is that you left out struggling to remove the console lid release button trim & no doubt broke the plastic catches 😂 I don’t blame you if you did their a pig to get off.
