I'm new to the forum. I don't have a Mini yet, but my daughter does. She is 2k miles away and I'm researching her difficulties. Her accelerator pedal input is intermittently suppressed. I'm thinking that the brake input to the cruise control has a fail-safe feature that is causing this condition (happens in repeated brake use scenarios (traffic, drive thru etc). Are there two brake switched mounted in the same location for these two functions? are they on the pedal lever under the dash? on the engine side of the firewall? Are these switches identical or different parts? Thanks!
It could be the DSC system. Depending on the year mini. If it detects well slippage it will remove power. what year and model Mini does she have? Have her take it by a parts store and have the codes read. Knowing the codes will help. With out that it is pure guessing.
