My M reg Pug estate has recently developed a ticking noise that is coming from under the near side front wing. It appears to be related to battery voltage and is loudest when the engine is running. It goes quiete with the key out but can actually still be heard with a screwdriver, at least for a while. Air con does not work but switch in or out makes no difference. What is the device under the rear of the N/S wing? this appears to be the source of the noise. Haynes doesn't help. The electrics are shot on this car as an "Auto electrician" attacked the car to stop the battery being flattened. I guess this may have been someone at a garage as I bought it with an MoT that it shouldn't really have passed.

If your still awake, Thanks for reading.
