Hi, I have perchased a 2015 XF 2.2 the charging system is working fine but the warning light tells me that the charging system is not working.

Please help as the garage has tried everything and is unable to fix it. The car is absolutely imaculate in every way, just as new.

Hi Cyril

If you have just bought it at the garage the seller needs to sort it or give you a full refund

Don't ignore the warning light Cyril, it's there for a reason. If it's on when it shouldn't be, the charging system is definitely NOT working fine!

What makes you think it is fine?

Without looking at a diagram and not knowing that model, i can only make assumptions but either way, something is bringing the w/light on. Worst case scenario is the alternator isn't charging at all - it might be putting out enough voltage to appear to be charging on a basic voltage charging test but not putting out enough current to cover everything needed just for basic running. End result will be a non-start but in the meantime, rough running is likely to happen with the potential for ECU damage.

Best case scenario is a fault in the w/light circuit and the alternator is charging on residual magnetism in the unit in which case the flat battery will likely be avoided but the alternator is likely to be damaged ultimately.

Get it back to that garage, if they try and fob you off, find a good autoelectrican near you and get a second opinion.  Even if you have to pay for that and seek recompense from the supplying dealer under warranty you should get it sorted.

Hi

You need to plug in with Jaguar SDD, that will tell you why the fault is on

generic code reader are generally useless unless is a simple engine fault

usually a battery fault, some cars have two batteries, the small one is overlooked and usually the problem

Hi Joe, thanks for the advice, will take the information to the garage from were I bought the car and hope he can fix it for me. I am very reluctant to give up with the car as it is in such good condition.

Thanks again.
