I've a freelander 2.00 tdi, T-Reg. Think i've got a serious problem, when i brake my headlights come on, now i know there's a short somewhere. Now here's where it get worse, when i put my headlights on, my engine starts to hesitate, and it doesnt respond when i put my foot down, it only works if i put my foot on/off the accerlerator pedal. I've tryed to make sence of it, but its hard to explain. It only happens when i put my light on. do you think it could be the ECU.
