I have just bought a W166 ML and I have found that the rear parking sensors are not working correctly. When you engage reverse gear the four red lights light up and the beeper sounds for about a second. The manual states that this is not a failure of the parking sensors as that is followed by the parking sensors turning off and the red light on the parking sensor switch lighting. According to the manual it is dirty sensors (they are not) or interference and you should drive somewhere else (Somewhere else isn't necessarily where I want to park and it doesn't change things anyway).
Has anyone else experienced this, and if so what fixed it? The car is Mercedes "Approved used" so it has a warranty but do you think it will cover this as the manual says it isn't a fault unless the parking sensors turn themselves off.
Any insights would be appreciated.
