How to activate and reprogram the computer modules
As you may have noticed in the W220 section, Im in a research process.
How is it possible to activate and reprogram the computers and controller modules in a W220 ? Does there exist a PC software that can do that - or is it top secret and for the manufacturer and dealer only to do ?
Did visit my car doctor who normaly takes good care of my W201, he was sitting tapping like crazy on his computer trying to communicate with a guy in Far East to get a cheap main computer for some french space ship car. Manufacturer wants 6.000 Euro for the computer, but he tries to get it for 3.000 Euro !
He told me they get 5% off such electronics stuff from the manufacturer, and then they have to return the faulty item. Gosh - how the manufacturers make gold on computer and moduel repairs/exchanges.
Well - he told me they have to activate the computer and modules, then program the whole thing - using a special very long code, which they get from the manufacturer. He also told me that they offen exhange such information with the dealers and other shops ( very unofficialy )- but that the dealer not always give them the neccesary information.
So having a OBD2 scanner dosnt actualy solve the problem, only indicates whats could be the problem. Still - officialy - only the dealer can activate and reprogram modules and computers.
Or what - what do you think ????
