If they see a JB4 they will flag it in their system. BMWs can also do internal detection to see engine parameters up to and at the point of failure, which means if you're running a piggyback BMW could deny warranty claims. Bmw will detect your JB4 if they dig deep enough.

I've read that dealers can detect it and potentially leverage that evidence against a warranty claim if they can reasonably suspect the JB4 contributed to the issue being assessed.

Hi Guys As the question states can jb4 be detected by your dealer? I have heard rumors that you can do a reset on the car or something similar so the dealership can't detect it Thanks. Help needed to scan codes with jb4 Hey guys, I got a check engine light on my car and i was wondering if anyone can help to figure out what they are exactly. I've had the jb4 installed on my car for a little over a month and i got the the half yellow half clear engine icon on my dash so i pulled over and then a small check engine light came on.
