Which bulbs are you trying to replace, I have changed the fog lights to LED but I dont think they are monitored for bulb failure as they are not a legal requirement, I have also changed the side repeater indicators for LED units and no errors. I presume the E's have a lower threshold for bulb warning activation. There was someone on eBay selling LED bulbs for the rear indicators on the D but they were supplied with a resistor that you had to fit into the bulb holder with the bulb.
