Engine: D5: - won't start after going through a flood

Hi
I would really appreciate any advice on this...
My 2007 S60 D5 185 stalled in a puddle, water-dampened the air filter, but didn't appear to get into the engine. the water got into the exhaust and probably soaked the DPF. I stripped the airbox, connectors and dried everything out. After ten days a bump-start and jump-start and a recharged battery it finally started with the key after the bump start didn't work. The car shot loads of water from the exhaust. Smoked terribly, but drove and cleared itself apart from a lumpy idle when warming. The car started for 3 weeks and the smoke and lumpiness at idle until warm lessened and I have run a DPF cleaner through it and done a few hundred miles including a hundred mile high revs journey to try and clear the DPF. The other day the car started and stalled whilst I was de-icing and won't start since. The battery is charged, tried jump starting and some engine start spray, just won't quite catch. Once it had started and done a couple of miles the exhaust would be absolutely clear of smoke even when revved so wonder if it might just be new DPF and or sensors that are needed I have a 042 code that comes up which can be a bulb failure and a back one has blown. Apart from this it was fine though did temporarily go into a limp home mode a couple of times before the flooding then cleared itself. Sorry for the long message just trying to put as much info as possible.

Many thanks

Ian

how deep was a 'puddle' to get water up in the airbox, and make you stall!?!? Or did you approach it like Jeremy Clarkson?

In terms of advice, you need to plug it in. Could be infinite reasons for non start, likely a sensor of some sort preventing it firing. All manner of things could be knackered with water damage, some minor such as a dirty contact on crank sensor, to major like knackered DPF etc. The smoking on start makes me think DPF is knackered.

I suppose it could possibly be a slightly corroded connector in a multi plug, if its gone 3 weeks after the water splash. might be worth disconnecting and re connecting as many of the engine bay multi plugs and sensor connectors you can find, well at least that's only a bit of time and no financial cost of swap outs to begin with

sometimes water takes its time to create an oxidized layer on a connector.

Thank you for your reply. I suspect DPF is probably the issue. Got it started today and did 100 miles. Doesn't like low revs as I suspect t higher revs the exhaust gasses go through the DPF easier. It flies down the motorway once at normal temperature then get lumpy at low revs. Next step will be a new dpf, luckily I can find a new one for £128 so worth a shot. Otherwise I have a 250hp Volvo(tuned!) that feels like one with half that. Many thanks Ian

The puddle was slightly deeper than the exhaust and have been through it every year that it forms just got unlucky this time!
