XF 2.7D built 2008. In the past few months I have had an intermittent parking aid issue stating: parking aid unavailable. Please consult your Jaguar dealer. I took it to my local dealer and they found nothing wrong. However, in the past few days the same message comes on every-time I start the car.....Please can anyone help?

 

Failing or low battery, most likely.

The EPB draws a lot of current.
