118d Low voltage issue

Hello, I recently had an issue with my 118d where after pressure-washing my car,I get in and a whole bunch of notifications come up.The ignition is on,but the car won't start up(it doesn't even crank)/A couple of the issues on the screen were:
- Fuel supply malfunction - Full performance not available
- Traction control malfunction
- Tyre pressure sensor malfunction
etc.
windows,locking/unlocking,radio and stuff all worked fine

I managed to tow it to the service center from the wash and they suggested the battery being the culprit. They tried to start it up the following morning and it started up without any issue. All of the error codes they inspected(and there was a whole bunch of them,maybe 20+. were all related to low voltage). They changed the battery afterwards. The car drives perfectly fine now,but it did so before i had the issue as well..

Now from my logic, can the battery just decide to give enough voltage after one day to clear all of the issues? I am thinking this is not related to it. What do you guys think about this? Maybe the pressure washing part was a coincidence and this could have happened any time? Either way it was a pretty bad thing,considering I couldn't get the car in neutral as well...
