Loads of warning lights!

Hi just bought a 3.0 Litre diesel GLS, 66 Plate.

Had it about 3 weeks, came up with a ln auxiliary battery malfunction, then got all these lights on. Changed the small 1.2AH battery in the back and seemed ok. But all these lights have come back on. Any advice welcome!

Many thanks

how old is the main battery. These cars (along with VW) act very strange when the main battery is faulty. If your main battrey is 5 years or older I would swap it with a new one

I'd start checking all of the fuses. Then get the main battery tested.

Have you scanned it for codes? Check the battery connections for clean and tight. Check the power distribution and ground points for loose fasteners.
