Warning lights, oh no.

But, I plugged in my 'cheap' yet capable code reader and discovered on my iPhone the problem was the 'accelerator actuator stuck closed', although it wasn't, it had been 10 mins before as the next message/warning was Limp Mode. I un-stuck the sticky actuator, reset the warning lights, and all good!
The code on the car was 042, by holding the trip button in for 10 secs or more.
I'm sure there will be more problems, just glad I fixed this one, here to help if anyone gets stuck too.

Best
