F55 MINI Cooper S Warning Light/Map Issue

[Linkin]

Posting this on behalf of my daughter who has an annoying issue with a Warning Light on her F55 MINI Cooper S Auto

Here's the potted history:

Purchased in June 2023, from a large, reputable Ford main dealer.
The MINI had been traded for a Ford and they kept the MINI for resale.

A while back, the MINI threw up a warning light and requested 'Service Transmission Oil'. She booked it in to a local authorised MINI Dealer to have the work done, which they did.
The issue is they couldn't re-set the warning light and told her that the reason was the car had been mapped, so they couldn't/wouldn't re-set it.

The original dealer who sold the car wouldn't have known about the map.
My daughter wasn't aware of the map until the local MINI dealer mentioned it.

So, she needs the warning light to be extinguished, but no local ordinary garage seems to have the right software tool to do this.

Can anyone recommend an independent MINI specialist in North Essex area that may have suitable hardware to be able to extinguish the warning light and possibly return the map to standard?

Thanks in advance.
