Just popped up on mine this evening
I had a long run over the weekend, a 200 mile round trip with some running around whilst away and I did notice yesterday morning whilst driving around that for one moment in 3rd gear accelerating, there appeared to be a lack of power, but changed down, put foot down and all was okay.
Been driving around all day today on and off, went out tonight on a mile and a half drop off and when I came back to the car and started it, the MCS warning light came on accompanied by loud beeps. Switched it off and back on again, no beeps but warning still there stating "go to dealer". Went home and dropped in a shop for some beers, came out and same again. Got home turned off left it a few minutes, turned her over and still there.
Guess I'll see what it's like tomorrow morning.
