Hi everyone, I know ive posted about this in the past but my MOT is due in 5 weeks so im trying to figure out why my car has a management light on. I was involved in a car accident not so long ago and got my car repaired, When I got my car back I had the engine management light come on and argued with the insurance company that they should put it right. I later found out that it was my oxygen sensor and it was located at the front of the car.
So I came on here to ask for advice about it, and got told to look for anything that was hanging down from the car, since then ive noticed that there is a wire not connected to anything ( In the photo please follow the website link) can anyone offer any advice.
The 2nd question is it a expensive / time consuming job the get this put right any ideas would be fantasic.
Car is 1.6 Astra club. 03 reg
