Hey Aloys,
Do you have any contacts at Hella International in Germany? I only have one gray "key" or probe or what ever it is called for my system.
I tried contacting the US Hella distributor in Georgia and was told the system was not sold in the US and I would have to contact Hella in Germany. I went to their web site, but it referred me back to the US distributor!
I could not leave any message directly to customer service at Hella in Germany, so I left my request with their web master. That was several days ago and I have not received any answer. I could not find any mention of this system on their site as well. What do you know about getting more keys or even a complete system to replace what I have now?
Vielen Dank,
Mike
