If youve got warning lights illuminated then theres obviously a problem, a quick plug into the diagnostics machine would give the reason, but I suppose you dont want the cost.
If youve just bought it why not ask the people who sold it too you, they must have had a reason to disconnect it or had a problem, maybe thats why they sold it?
Were the lights not on when you had a test drive? if so why did you buy it without asking for that to be corrected?
It seems many people just rush out and buy a MINI and then find theres something obvious not right with it, many times thats why its being sold on, that ought to have been noticed on the pre purchase viewing?
If 200 people have looked at your thread and not replied they obviously dont know either, it wont be because its a secret, they dont know, but might have some similar problem and looking for ideas, it wont be because they just want to ignore you.
I dont have an old Gen 1 MINI so I cant help with pictures here either, sorry
