Ignition light disco

[Andy_B]

Hi all.

I have a 2019 S3 that is giving me an ignition light funky disco  from time to time. The ignituon lights stay on or flicker even with the engine running.

Sometimes the dash goes blank and gives me "Ignition powered off" or similar and, according to my better half to whom it has just happened, the heater fan goes off.

It will start and drive as normal and has occurred while driving.

I don't know if its related but each time I start the car the rear occupancy/outside temp display, which are at the same location on the dash, flicker between the two displays.

I have had the car since September and its happened 3 times including today.

Any suggestions welcome.

Thanks

Andy

The prime candidate to my mind is a dying battery. The recent cold weather is revealing the weaknesses of all batteries. If it is the original five year old battery I would not hesitate to change it; if it is more recent I suggest you get it professionally tested before buying a new one. Make sure you get any new battery coded to the car.

Ok thanks. It's not something I would have considered as it starts on the button.

I have a decent tester so I'll give it a try.
