After i discovered the pinout from renault is wrong, i measured the right pins and now it works!!!

I already mentioned that the german version of the synth has a french accent... BUT they even totally invented new words that do not exist in german!!

You can either say "Bremsbeläge" or "Bremsbacken" for "brakepads" ... but "Bremsplaketten" is not even a word :D ... 

If you put (german) "Bremsbeläge" into a translator to french you will get "les plaquettes de frein". (french) "plaquette" directly translates to (german) "Plakette". Now it makes sense why they used "Bremsplaketten" ... its not right... but it at least makes sense now... French is an interesting language.
