Hi, I have an e46 320d 53 plate, I've fitted an aftermarket hid kit I had. I tested them over a battery before fitting and both worked fine. Now there fitted to the car they don't turn on and I have warning errors on my dash for bulb failure, I have power at the ballasts and all connections are good, am I right in thinking I need the can bus warning cancellers due to different resistances of the bulbs? Would this stop my lights turning on? Thanks for any help!
