Knocking sound stationary in reverse.

[Cozza]

Hi Guys.

Small problem Jaguar XF diesel when sitting in reverse with foot on the brake just idling I can hear an intermittent knock knock sound from under the car and I can feel it through my feet.

It only appears to be in reverse it sounds like a solenoid going on and off, the car dives absolutely fine and when on the move I hear no noises.

Recently had a service but cant see how that would have had an effect.

Any ideas?

Hi Cozza 

 

i have the same same issue with my XF, started happening a month or so ago and exactly as you described. Did you ever work out what the problem was?

 

thanks.
