Hello everyone, on the weekend I washed the car, it is an A4 2013 and when I turned it on, the direction indicator turned yellow with a message something like "drive system error" the only difference is that the steering wheel did not return from the All alone, I did not move the car all weekend yesterday I took it to work and back the warning light changed to red and the steering wheel got very hard, I turned off the car and when I turned it on I got another message that the star-stop was not working system error, what led me to think that it could be the battery, someone else went through this?

I passed the auto scan and this is what it gives me:

I appreciate your time in advance.

Does the car have the original battery? The terminal 30 voltage looks low. Can you charge the battery, clear the errors and see if they and the warning lights return?

Yes is the original, the battery charge is at 50% according to the MMI but I checked it with the vag, but I will try to charge

Blocked scuttle drain on the drivers side is worth a look, if that area fills with water there is a possibility water could get to the ecu, lift the scuttle and check on the drivers side.

Do you have a pan roof? The drains run down the A pillars and if they leak at a join in the hose, water can enter the car a cause all sorts of faults.

checked, it had some leaves but no stagnant water or signs of humidity, if it has a panoramic roof.
