Implausible signal error code P046C

[LambethBoy]

Hi Guys, am going off on my usual euro road trip next week and thought i'd give the van a check over today.
Below is the VCDS reading and im not sure if this is something that should need seeing to prior to leaving as it is showing intermittent.
Any ideas what the fault may be??

Vw advise to leave this fault (just erase it out) if its the only engine management fault that's logged.

Interesting. I did erase it out but it comes back.
Incidentally I checked an old scan from April and it was all clear then…? @mmi @Loz any ideas guys?

I get this occasionally, nothing’s dropped off yet. VCDS can be a dual edged sword.
