Well guys, I just got the Elite V2 for my 2018 230xi and installed it today. Once the car warmed up the first 50% acceleration I did the car felt like it massively lost power, after that it felt fine. When I stopped and restarted the car I then had a CEL. Did some additional driving and restarts and it eventually went off but after I ran to get gas it came back on.
Going to through the bypass plug on and do some more driving but I'm concerned. Thought the V2 was having less issues but now this is happening. Debating to just return it as I don't want to get stuck on warranty hell with Dinan when I don't even know if I'd be happy if the device was working properly.
Also I do have a Scan Tool and one of the errors is listed as permanent and only can be reset through clean drive cycles.
