    Hi lads,

    I have a 2008 Ford Focus 1.6TDCi. Earlier today I was driving along a flooded road that I thought was passable but halfway through the revs went up to the top of the range and the car conked. I tried after and it now won't start, and had to be towed out of the water. Anyone able to tell me anything?

    Yes. This is probably hydrolocking.

    An engine gets hydrolocked when it breathes water rather than air. This usually happens then the car drives into a pond, lake or river with the engine running, or when there is a huge puddle on the road

    Once a cylinder fills with water, the compression stroke jams or "locks" the engine (because water does not compress) and the engine cannot spin.

    If you are lucky it could just be the electrics, or it could have taken a small amount of water in the intake and the engine could have hydrolocked.
    If its the latter its new engine time, usually damage is severe and includes bent conrods or more.
    Electrics can be as troublesome if there is major damage.
    Hard to know at this point but whatever you do, get it seen and drained straight away water sitting in the electrics and engine can do a lot of damage as its usually very dirty.

    Suppose it's with a mech now so they will check and let you know.

    Don't make any attempts to start it until someone looks at it.
