I’ve not experienced any problems – YET!
I have a Kodiaq iV on order and wanted Brig-Ayd electronic throttle, only to be told it wasn’t possible on that vehicle. My adaptation company looked into it further and said that only the Veigel one was suitable. I had a conversation with Veigel’s rep in this country, who said that they would have to fit it in their workshops in Aylesbury. That is due to be happening next week (been waiting since early December), and should have the car about a week later.
I’ll update once I have the car.
