Moin, I just got my breakout from the dealer. Now it’s Saturday and the dealer is closed. I have a Jekyll and Hyde with the electr. Can-bus system. First you could switch through three steps with the electronic switch red green/red flashing and green (so open). That’s no longer possible. The dealer said that you would have to switch on the workshop mode of the J+H via a switch combination. Someone knows the switch combination and you can use it in normal operation at all. I find it partly quite good to drive at half volume. Would be nice if someone could help me on the fast. Greeting Jörg
