Opened the bonnet and gave the engine a quick spray too, not much just a bit to get rid of dust. Obviously I did not have the engine running as we know petrol engines will stop at the mere suggestion of water near the coil pack, a diesel will lovingly take a big drink and bend things.
I did not use the car till Saturday as was not very well for the remainder of the week. I get in and it fires up immediately as it always does
I try to crank it and it sounds very slow on the starter
My thoughts then turned to hydraulic lock + expense. Pulled airbox + pipework / turbo plumbing off to find them quite damp but not really bad. Tried cranking again it was still slow but not as bad as it was. Put pipework back and whipped a couple of glowplugs out and tried cranking it again (stop solenoid disconnected) then put them back. I decided that if damage was done then it was done so was not at this stage worth stripping much further, ie: whip injectors out etc.
It started fine had a tiny misfire complete with smoke cloud for about half a minute but its been perfect since
Done a good hundred miles since including a fast blast and no signs of any problems, it certainly has all the power it did if anything its actually quieter but that might be my imagination.
