It may be worth checking all bulbs are correctly fitted and of the correct Watt for their function.
This info should be printed on the bulb housing.
Sounds obvious but the lights are controled by the one of the ECUs and if it gets a wrong signal back it assumes a fault and the lights wont work.
Quick and simple to check but it worked for me.
Hope this helps
