Hey mates, I'm seeking advice to fix my Patrol GQ 2.8 Turbo Diesel after having tried it as a submarine in a deep puddle. My bad, it's my first 4WD and I went out with some experienced mates who didn't try to stop me from trying that one (I don't have a snorkel on the car - didn't even know I needed one).



The mech removed the water from the engine, changed all the oils, two filters, charged the battery and let the car dry up for a couple of days...then he managed to start the engine. He also told me that the engine would have some difficulties at the first start of the day for a long time, but it should be fine as soon as the water fully dries up.

For a couple of days the engine actually struggled starting up, with white smoke coming out the exhaust, but then the troll used to run smoothly.
...Until today. Today I cannot start it, no matter how many times I try. White smoke is still coming out of the exhaust and nothing else happens.

I searched the forum for some similar experience and this is what I found
FLOODED DIESEL ENGINE
but I still don't know how could it help me (total rookie).

Mh, another thing: I'm also experiencing some electrical faults, like some indicators on the dash not working. Better to have a full check at an auto electrician or it might be just a matter of changing/coating with WD40 some fuses?

Thanks in advance for your help!
