I will definitely be investing in a new battery. I can’t say for sure this one is 7 year old am just presuming. I have only owned the car 18months. Cost me a !Removed! fortune. As for the “warning messages” it doesn’t come on straight away. Takes from cold about 5/6 minutes before they come up. Once warm it’s a minute after driving. No power loss ect

Is there a way to test before purchasing a new one cause I believe I read that a new battery would have to be coded to the car?

The car is on a 17plate and I believe it’s the original battery

I have an Audi A4 2.0 diesel on a 17 plate. had a new timing belt done. Car running perfect. However the following comes on every time. start/stop system fault: function unavailable Driver system fault: contact Workshop. anyone have an ideas what could be causing it? Had an independent garrage plug it in to diagnose it. No fault codes at all.
