This is a detailed video showing exactly how to fix an ABC ‘Visit Workshop’ fault (B22/10) on a 2004 Mercedes SL55 AMG. Rather than replacing the entire hydraulic strut, this video shows you how to replace just the electronic plunger sensor and fix the ABC fault. There are detailed instructions for removing the boot lining and putting the trunk lid (boot lid) in 'service mode'.
The end of the video shows you exactly what parts ands tools you need, where to get them, and how much everything will cost. This cost us less than $200 to fix.
The previous video gave a little more detail on how to scan the car for this B22/10 fault using the iCarsoft v2 scanner.
