If they can do it for VAG-TACHO (Coding/Mileage) and also VAG-COM (Diagnostics), meaning you can change the mileage and recode the IMMO2 on cars like the A4, Golf, Passat, Octavia, Leon etc.. for £40! These were Can-Bus applications as I remember my rear door locking module was giving an implausible signal causing the deadlocks not to set and my little red led not to flash on the drivers door. Common dry solder joint, besides the point. Isn't there a simpler hacked interface/application for the Can-Bus on a Mercedes-Benz, I really like to see what's going on with my rear windows. There must be, there are surely more MB nuts than there are VW cults out there!
