Vehicle: Superb L&L 2020 with Virtual Cockpit

Turned on the ignition, lowered all the windows and then started the car. Received a ACC not available and the Red Warning Triangle ⚠️.

A quick scan revealed the following fault:

Monitored Display Output

B159AF0

A quick Google doesn't reveal much. A discussion on a TSB for a 2019 Jetta, requiring a software update.

The fault cleared off the dash after I powered down and locked the car. The code cleared with OBD11 . I'm hoping it was a random fault.

Having said that, Sunday out for a drive and on a clear patch of straight road I had 2 emergency break warnings on the dash ( obstacle ahead ).

Anyone have a little insight?

Without stating the obvious have you wiped the sensor clean, and check it is not a tiny bit pressed in etc.

Not unheard of in the summer for it to get hit and splattered by some big flies (or similar) etc. All of which could confuse it.

Yes, checked it the cover was clean.

Now unless it was a big ass fly that flew in front of the sensor 😁

I was more concerned with the Dashboard fault 😕

My google came back with this...any better an idea? Hopefully just a software update?

Otherwise there's always the potential "how old is the battery?" question when electrical gremlins start appearing...

Yeah, I'd seen that summary. I wonder has the firmware been corrupted. The battery has been replaced at some stage, it's somewhere between 18 months and 4 years at a guess. Currently there is a Halfords battery. Hence my assumption.

I'm hoping it was the voltage drop in the battery that may have caused the glitch. I've yet to see the fault since, and had no visual fault.
