hey,
As the title says i was on my way back from college earlier and came round a corner and there was a BIG puddle, and basically didnt have time to slow right down and there were cars on otherside of road so no avoid it
Anyway after going through this puddle i put my foot down and there was very little power (even worse than usual!!!) and also a light came up on my dash (the yellow one on the middle row on the right)
and briefly the EPC light when i stopped.
Basically i have no idea what has happened, i suspect water in electrics ???
But was hoping for some advice!

Thanks in advance, Will

Muppet, plugs coils buy all new as pointless trying dry them out,
My m8 did it ruin his engine

Anyway thanks will see how it goes tomorrow if its still bad ill get them all replaced
