Welcome Daniel,
Multiple warning lights, and particularly with associated stop/start failure can be typical of a below par battery.
How old is your battery?
It would be worth having its efficiency check with a sophisticated testing facility. Don’t assume because it starts OK, that the battery is serviceable in all tested parameters. The likely-fitted Battery Condition Monitor will probably have a different view!
Need a new battery? Invest wisely in a min. of 4 year warranty batteries. I’ve used Varta/Bosch to good avail, and I think Exide is also well respected.
I always buy from on-line specialists at most favourable prices. Suppliers inc. Tayna, Battery Megastore, and others.
It is almost certain that the new battery will require coding to the car.
Kind regards,
Gareth.
