So its been raining here a lot in the UK and puddles are forming everywhere! Some huge to say the least.

I drove through a massive puddle which was down a country lane and as soon as i exited the puddle the yellow light came on

"Engine Warning. Reduced power mode"

I've left it for 2 hours but still nothing. Seems when I put my foot down it splutters when the turbo normally kicks in!

Any ideas?

Thanks in advance!!!!
