Mini One start stop problem

Alright so the start-stop system on my 2018 Mini One diesel is playing up. The engine shuts off but then it won't automatically restart. I've got a warning light showing in the speedometer and there's some error stored in the memory. I'm guessing it's a battery issue. Any ideas?

Sounds familiar. My Mini One had a similar start-stop system problem. The engine kept shutting off and the automatic restart wasn't working. Was there a warning light on the speedometer too? I'd check the battery first. It's often the culprit.

Yeah the engine was cutting out and the dashboard lit up with a warning light. Was your issue really just the battery? How did you figure it out? Was there an error code stored in the memory?

Definitely check the battery. I had the exact same symptoms on my Mini. The error code pointed to a heavily discharged or defective battery. I'd take it to a workshop to get it checked out properly. They can confirm if it needs replacing.

Big thanks for your help. I got the Mini back from the shop today. They confirmed it was a battery issue like you thought. Cost me 290€ but at least the start-stop system Eco mode is working again.
