Great video again! I wish the engine control unit recorded a fault when it can see that the key has been turned to ignition and battery voltage is okay but the crank sensor shows no movement in the engine. That should be sure enough fault to be worth logging. It would have been interesting to know if the actual fault in the old computer was just cold solder joint or if the actual silicon had a crack. Re-soldering a cold joint would be a permanent fix but crack in silicon cannot be fixed. However, I have to say that I really don't understand the thinking of the designers! No computer in the world likes the temperatures commonly seen on top of an internal combustion engine so that's really poor location for the computer. In addition, the thermal expansion of the PCB, silicon and solder are not the same for all the parts inside the engine computer so this car is sure to cause cracks in long term use, especially in climates with high temperature changes over the year.

VAG (from Germany, too) has been doing lots of stupid things, too, but as far as I know, even they haven't done this bad design solutions. VAG puts the computer close to the under hood fuse box in a water tight plastic box.

@Steve Interdonato That or planned obsolescence. If it lasts warranty time, it's good enough for the manufacturer. And you will not see 3rd party engine control units beating the OEM prices so you still have monopoly in spare parts.

@PaulShalahm I think most people would agree that Mercedes has very competent engineers. Unfortunately, they also have marketing department and when these forces clash, the total output may be less than optimal.
