I just purchased some Sylvania 921 Led bulbs for the reverse lights on my 2012 Mini Cooper S Hardtop and i get the exterior lighting system failed light on my dash once I replaced the bulbs with the new LEDs.
I put the incandescent bulbs back in and the error goes away, has anybody else run into this issue? If so, what did you do to try and resolve it?
Any ideas for me to try would be appreciated, I'm hoping to go with all LED upgrades for my car.
Thanks
