I hydraulic locked a 306 1.9DT. The water was picked up by the exceptionally low air intake mounted below N/S passenger bumper and a slightly deeper than expected puddle. After the car stalled I managed to get to going again, drove home and the next day replaced the soggy air filter & changed the oil. All was fine for about 300 miles.
Then whilst travelling in the outside lane of the motorway doing 70, one of the con rods snapped punching a hole in both sides of the block and the sump. I can only describe the sound as driving over a bag of spanners!!
Brown pants moment.
Sell the car.
