Sounds like a daft question but can anyone tell me that if both reverse light bulbs have 'gone' would this cause my reverse sensors not to work? Was working perfectly before i went into a certain stealership now theyre not working! Its due to go in tomorrow for them to look at it (even though they say they havent touched anything to do with the sensors) This is after i spent £360 on a service inc. brake fluid change and got home and all fluid (coolant) was down the road. "Sometimes these things just go" was the reply to me suddenly wanting a new coolant hose (needless to say there was NO way i was paying for a replacement). OOps sorry i went off a bit....can anyone answer my question?
