02 Audi A4 light sensor issues and engine management light
 

Hi

I have had nothing but issues lately. My car always says my right indicator bulb has gone so I replaced it yet it still says it's gone so it isn't a bulb issue . I also get warnings when I turn my lights on to say that the rear right bulb has gone but it hasn't.

I have checked and they aren't working but every now and then the do. Has anyone got any ideas please:confused:

I have had the engine management light on for probably 2 years now too with error code 0118 which is engine coolant temp running high. Googling says replace sensor which I have done twice with no success

Any ideas for either greatly appreciated as I want to sell the car due to me getting a company car soon!
