Gives 307 ERROR MESSAGES

Friends have a good day. I have a 307 hdi 2004 diesel vehicle. two days ago, I washed the car with water cannons (I did not lift the hood) When the washing was over, the battery sign burned when I left and wrote battery charger fault and went off 2-3 km later it did not burn again. On the way to work this morning, the airbag lamp came on and the road computer also gave the airbag fault error, and I drove the car for about 30 minutes, and the lamp never went out, I wonder what a nuisance it might have been.

Probably water has escaped. A problem in all 307's. Wrap the top of the steering gear fuse box with a cloth.

If errors persist, it is useful to connect and look at the diagnostics.

For the last 2 days, the car did not turn the remote control on or off, then when I manually opened and started the car, the remote control started to turn on and off, I just took it to the master, he said what you said, probably we should have gone water, he said we should open and look, but I hope it gave a day to the monday because of the intensity, it is not a costly problem.
