Hi all, I have had my x type for a week and I lost my reverse sensors and reverse lights, I changed the bulbs and fuses which had no effect and therefore bought a new switch. I had to disconnect the battery and replaced the switch and everything was back and fully working. On my first journey out the engine management light came on, car is driving fine, is this as a result of what I have done or a case of getting the codes read?

Thans thermo, i will get the codes read, when i was test driving the car it was a bit lumpy and the garage repaired it as a wire to the egr valve was shorting, hoping its not related to that.
