Drop in revs when cold
As the title suggests, my mini is prone to a serious drop in revs when moving off when cold. The revs drop to the point that it feels like it’s going to stall but it rarely does, it also makes a horrible rattley noise when it does this. It’s mainly an issue on my way home from work as I have several junctions and roundabouts to negotiate before the engine warms up. Any ideas???
I take it that it is fine when warm? I wonder if it throws up any codes, your welcome to use my code reader if that would help?Originally Posted by Julz
Yes, fine once it’s warmed up. It’s been on a code reader at the garage (thanks for the offer) a few months ago and all it was coming up with was the issues with the bypass valve doo-daa (now replaced).
Have you had the car remapped? Could be a map issue
