My 2009 Model XF 2.7D Luxury has been trouble-free in 3 years of ownership. Last week however, the low washer fluid warning message came up when the water bottle was full. I drove the car this morning and the Gearbox Fault, DSC Not Available, Parking Brake Fault messages came up as well! It doesn't seem very likely that the car has suddenly developed all these faults. It certainly drives fine as it did before. It seems as though there is some problem with a sensor or control unit flashing up these incorrect messages.

Is there anyway of clearing all the messages by going to a independent with a fault reader or will it be a main dealer job?

The low battery light has occasionally come on since I've had the car - I got the battery tested shortly after I bought the car and it was fine. I've started doing some research online and maybe it's possible the battery is low and this is causing problems? I've also read that if there is a fault with the parking brake switch, this can throw up many incorrect fault codes.

Greatly appreciate any advice/experience/information

I've just made a quick video to show the warning lights at the start-up:

Get your battery load tested again.

If that checks out then have the battery connections removed, throughly cleaned and then re-attached.

I'm betting your battery is on its way out. Causes odd faults in modern cars so dependent on clean power for the computers.

 

had abs dsc and gearbox fault also low washer fluid but was full1 bought new battery abs fault still there rear wheel sensor but other faults gone. will update if ant return

 

Things should reset/clear after a few start/restart cycles

 

This happened on my VDP. It turned out to be a bad Throttle position sensor. I replaced the alternator and battery first, which cleared the problem for a while, but it returned a month or so later. Took it back and they got to the root of the problem. Never had fault warnings since
