Hello, My AG4 box has frozen g22 speedometer sensor base axis and that is pain in the neck to replace. I am currently building another solution to workaround the problem. There is valid road speed signal coming from sensor g68 that I can verify with vagcom software. My idea is to use op amp to modify this pulse into decent mode for feeding into g22 socket. Has anyone already done similar thing? Br, Markus
