Btw, the reason I don't want to try this module just yet are not only the adaption values but to be honest nervous should something go wrong, probably won't increase the dealer activity.

yep, only 2 Power MOSFETs on the board attached to the chassis for thermal dissipation.
That 128 pin microprocessor looks vulnerable being on the same board with a 4 MHz 2 A switched PWM driver.
The big electrolytic caps are the first thing you can visually check. If the top of any of them is not perfectly flat, with a bump, the cap is gasing out and has started to fail.
