Okay so what does it mean when`

Code 31 is an AFM fault code which on my turbo came on when there was an air leak between the AFM & turbo, caused really rough running (like running out of fuel, anything but really gentle throttle kills it).

Not sure what the other ones are but you can find them on CygnusX1 anyway, most likely you either got some water where it shouldn't be (i.e. in the electrics), in which case all you can really do is disconnect & go through all the plugs with a good dielectric water dispersant. Either that or the pressure dislodged/damaged something in which case I'm afraid it's just a case of going through the affected component's circuits methodically until you find the fault.

First thing is check what your codes mean & go from there...

(By the way, I think AFM/AFM wiring faults can also show up as TPS codes?)
