Multiple warnings from rain

[Spanners70]

Hi all driving home in the early hours with a lot of standing water suddenly got a whole load of warnings below. Anyone any thoughts on cause or how to clear them before a trip to a garage…. Any help be very grateful

Airbag light
Diesel engine glow light on for a second then off for maybe 5 second and repeat like a slow flashing
Esp
Electro mechanical steering lock
Exhaust system fault
Brake system
Anti lock brake system

And when Driving straight or turning right fuel gauge correct at 3/4, turning left needle drops to zero and low fuel light
Also unable to lock or unlock from either keyfob, pressing the buttons nothing from the van stays unlocked.

Water ingress somewhere. (Prob engine bay areas)

Let it dry out.

. Reset all the codes.

See is the same happens next time it's wet.... If so investigate further.

Aye, it'll dry out if we have a couple of weeks of warm dry weather.....oh hang on!
