F48 X1 refused to move after UK MOT test

Hi all,

Last week I took my F48 X1 for an MOT service. The list of checks that they do is listed on this page but none of these checks involve connnecting to the car's OBD2 diagnostic port (as far as I am aware). I came back for the car and they told me the car passed the test with is expected as it's 5 years old and has new types with all maintenance done as per BMW requirements. They also told me they parked it around the corner. I wasn't too troubled about this as it's a small garage and they don't have much parking space. When I started the car the following issues were displayed in the dashboard:

• Driving Stabilisation Error
• Front End Collision Warning

When I tried to drive I got this message:

• Secure vehicle against rolling away warning

I checked the car and there was no sign on any crashes or even bumps. Obviously I called them back and they came and connected their OBD2 diagnostic console. They tried to clear the errors but they couldn't, the car kept refusing to move. I asked if they connected anything to the car and they said they didn't. Eventually the guy did a battery reset and was able to clear the console errors. The car then started normally and has been fine since then. The guy said these things happen sometimes but I don't trust them. I never had any unexpected errors before, all errors were valid issues. And certainly the car never needed a battery reset to clear errors.

Should I be concerned? How can these errors be triggered and then dissapear like nothing happened with a battery reset? Perhaps they tried to create a new car key?

Any ideas?
Thanks

They connect to the OBD port while doing the emissions test but that would not have done anything to the car it just reads the rev's and oil/water temp.
The only thing i can think of is the battery going low as they have all the lights on and don't always run the engine while testing the lights.
A low battery will start the car bit in bmw's can also throw up bogus faults.

Usually get 10 years out of modern AGM batteries
I too thought low battery, lights on, doors open - maybe an over night trickle charge and if it's been starting fine on the colder winter days worry not
