Hello all.

I have a 2010 XFR, V8 5.0 SC. Low mileage.

First issue, and most important is that the car has developed a very strange sound when pressing the ignition, almost struggling to come on. I have attached a recording of when I press ignition which I think highlights it well. Is the starter motor on the blink perhaps?

Second issue is electrical gremlins, particularly warnings every now and then on the drivers console screen, always after starting up. Typical warning is blind spot monitor not available, but now and then I also get some others at the same time like Adapative Dynamics Fault and an E-Diff one. The only correlation to when these occur is when the car has been out in the sun and warmed up. Bearing in mind ambient temperature where I am at the moment is 40-45 deg c so the car gets really hot if in direct sunlight for long as it is black.

Thirdly, is the drivers side reading light randomly comes on and off which is most annoying, especially driving at night. Any hints on these issues?

Service centre out here (Oman) are not known to be the most qualified so if I have some ideas in hand with which to guide them to solving the problems would be most helpful!

Cheers

 

Most of your symptoms suggest a battery on the way out, very common on a 5 year old XF.

 

Thanks didn't think of that. Will see if the garage can check it.

 

Reading light fault is known. Assuming you're not accidentally triggering it when reaching for the rear view mirror (don't laugh, some of us have discovered this "fault" ) then a new unit is the fix.

I agree the battery should be properly tested, either load tested or with one of the fancy new digital testers.

 

Thanks, I'm booked in tomorrow with the local Jaguar dealer. Hopefully they test the battery.

Any ideas on costs of a replacement?

 

Not where you are. Here a good brand of battery would be around CDN $ 150 I would guess.

 

You were indeed spot on. The batter was on the way out. Thanks!

 

Did that sound go away at startup ? ...very odd.

 

Thanks everyone. Picked her up yesterday from the garage. Battery changed, and some re-wiring done on the driver's ceiling light and she's feeling much better. 3 year warranty on the battery, bit pricey, about 150 GBP but that seems the going rate for imported parts like this out here.
