Thank you! 😊 Only soldering the easier points (resistors and pins) fixed my issues. I never touched the "microchips" and I didn't use a heat gun, only soldering iron and no extra lead.
Thanks for sharing. the DIM of my 04' S60R , sometimes it lose the electric power suddenly , and then resume , also it comes up SRS/brake warning , is this same case that you figure out in the video?
