Righto then... ummmm... feeling pretty stupid right now :embarassed:
Cut a long story short, I drove through a stream that looked ALOT shallower than what it is!
I thought I would be able to make it because it looked OK... got 1/2 way then the car just cut out, seems the middle dips down and it was almost up to the window
Managed to get pulled out by a passerby (who just so happens to have a large Land Rover Discovery 3 with winch ... wonder why...

) got recovered home eventually after waiting almost 2 hours in soaked clothes in the freezing cold and now have the car sitting outside.
While waiting for the recovery man my brother in law who came too see if he could help (take the P!ss more like ) said to try crank it over after we had waited for it to drain out as much as it would, the starter motor never spun (thankfully!) and there was nothing other than a short 'DURR', we called a mechanic my brother in law knows and he said not to try start it because it can cause a hydro lock and bend the rods or some catastrophic failure to that effect.
So do I just let it sit for a day or two then change the oil and oil filter and try crank it over?
What else should I do? and what else should I look for?
To say I am gutted is an understatement

Remember it's a Turbo Diesel,
