Check to see if the driver side floor is wet!

It was a little damp but it's been drying it out for two days now, so it should be dry enough. Is there a way to reset the sensor?

The problem is that a major wiring harness runs just under the drivers feet and those wires have a tendency to fray. Add water and they short out or short to ground. Get the carpet DRY, inspect the wiring and make repairs if necessary. Find and fix the source of the leak which is probably the cowl drain.

If drying the carpet area has not fixed the error and unless you have a VCDS cable o determine what the fault is a clear it, you should probably try to clear by pulling the negative battery cable under the drivers seat.

Momani,
I did get this problem fixed and it does take a few steps. The first thing I did was clear out the cowl drains, since they were clogged(I had a mouse nest in there...). Then I had to raise the driver seat where are you exposed battery. Then I lifted up the carpet to expose all of the wiring harness, my carpet was sopping wet. A wet carpet causes corrosion on the wires since they are taped with fabric tape.

Along the top end of the wiring harness where you sit your left foot, you will find a single wire that has 2 to 3 inches of fabric tape on it and you need to remove the tape. This is the wire with the corrosion that you will need to cut off.

What I did is soldered the wire back together and used srink tube to bond it so that it doesn't happen ever again. After this is complete your car should turn back on and be fine again. But I would also also let your carpet dry out.
After it is said and done, I would check your cowl drains about once a year.

Let me know if this works for you!
