Thanks a lot for your help.

 

i bought everything in FVD.de
Tail lights and the FVD controllers were 1388€ shipped
plug&play, no coding needed.

 

Just an update here. I was informed by Techart today that I can finally have a refund. Now they suddenly remembered me. Anyway, hopefully I will have my refund soon.

I would like to thank all my fellow 6speeders here that offered their precious help on this matter and also for their advice on some specific alternative and much more decent choices I have at the moment regarding the product I am missing for so long. Thank you very much. Hopefully the whole sad story ends today or at least soon enough when I see my money in my account again. Already contacted FVD.
