Jumper Auxiliary Battery Issues

My 2013 Citroen Jumper, diesel engine, is throwing a fit. 143743 km on the clock. Getting an error message on the speedometer, plus the error memory is full of issues. Seems like the auxiliary battery is playing up. Engine's struggling to start sometimes, and I'm seeing all sorts of weird electrical glitches. Suspect the battery isn't charging properly. Anyone seen anything like this?

I had a similar problem with my Volvo a while back. Error messages, electrical gremlins... Turned out the auxiliary battery was kaput. Have you checked the voltage on that battery when the engine is running?

Voltage check is a good idea. Where exactly did you see your Volvo issues manifest? Was it the same starting problem?

Yes, the starting was definitely affected, especially in cold weather. The electronics were acting strange too. I'd recommend getting a professional to diagnose it properly. Could save you a headache.

Thanks for the insight! I took it to a workshop, and you were spot on. Auxiliary battery wasn't charging. Cost me 290€ to replace, but everything seems fine now. Appreciate the help!
