Multiple error codes

[Goldenn]

I have a 2016 T6 TDI DSG. I last drove it on Wednesday with no issues. I went to start it on Friday morning and got a warning sound, Airbag error message, and several/all dashboard lights flashing. The engine did start, but cuts out as soon as I put it into gear. I ran it through Carista and with the range of errors that have all happened at the same time, along with missing sensor info and odd reporting, it definitely seems to be an electrical fault.

I asked elsewhere and somebody suggested something has chewed the cables underneath. I can't fully get under until I can borrow my friends trolley jack, but I managed to get a camera under and to me, the cables look fine. I know this could probably be anywhere, but on the off chance anyone's had the exact same errors, can anyone point me closer to the issue?

What revs is it idling at? and does the engine rev up ok while in neutral?

 

[Dellmassive]

Have you cleared the codes?

So they come back?

 

[Pauly]

battery voltage looks low, i would get that on charge before you have another issue to add to the mix

 

[Goldenn]

Thanks for the replies all.

@manfrotto Idling at 1000, and revs up fine.

@Dellmassive I cleared the codes but they came back immediately. However,

I came back to it the morning after and the dash had cleared completely (apart from a couple lingering because of the codes). I cleared all the codes and they didn't come back, and it went into drive this time.

I took it to the end of the road, the dash lights all came back on and I just managed to limp it back to my drive.

Sounds like an electrical issue (as you suspected) . Maybe wiring or bad earth, or blown fuse?
