I left the panoramic roof wide open during a rainy afternoon without noticing it.
All the seat were soaked and the rear floor mats were soaking wet, but not puddle yet at the moment I open the car. Front floor mats were almost dry.
I turn on the car and drove home for about 30 min (16 miles) before cleaning the mess and drying up the most I could with a vacuum cleaner and some rags.
During the commute home all electrical functions worked as usual.
The next morning the catastrophe started:
- No power steering (hard to turn)
- Airbag warning light in the panel activated (red light)
- Radio "disabled"
- No hazard lights indicator (visual & listening) on the control panel despite activation work correctly outside the car (same with turning signals)
- No power windows/mirrors/panoramic roof/AC/wipers
- Although fog light and speed lights on, no signal of activation on control panel
- plus a couple of more electrical things...

I took the car to the electro mechanic for him to scan the car.
First scan: "no response from the modules controlling these functions"
Engine/transmission modules responding to scan and ok.

Any idea of were to start to look for, and what might the problem(s) be?

On Monday I could get the exact scan message.

Many, many thanks in advance for your help!!!!

Wow that sucks...

this actually happened to my friends 2002 Jetta...but a little different, water had leaked into the passenger footwell from clogged sunroof drains...

Anyway, instantly his stereo kept turning on and off randomly...

A really good friend of mine owns a VW/Audi shop and he said after you vaccum the water, leave the car running for a little while with the heat high and set to the face setting....this will remove moisture from inside the car....

My friend vaccumed the Jetta yesterday but the carpet was slightly damp still...he left the car running for an hour and a half today, and when he shut it off, the footwell was dry and all the electonics were working perfectly fine again....

Idk give it a try, it could help...
