8, 19 and 5F would suggest you’ve got an aftermarket head unit?

Yes, as I mentioned above I installed an Alpine head unit and my suspicion was that might cause this issue. Is that normal?

 

[mmi]

I have replaced the stock head unit for an Alpine, so wondered if that might cause some of these?

Most likely, yes.
You could try to rectify by removing the OEM 5F-Infotainment from Gateway Installation List, and replacing it by more universal 56-Radio.

VCDS > Auto-Scan > Gateway Installation List

Untick 5F-Infotainment​

Tick 56-Radio​

Save, exit VCDS​

​

Cycle ignition OFF - ON
Rescan to see if the situation improved

 

[Mister-E]

Awesome, I'll try that.

 

[CJW]

Is that normal?

Yes and if @mmi’s trick doesn’t work then there’s no harm in them staying there.

I didn’t know about this trick so I’m going to try the same with mine.

 

[Mister-E]

I don't appear to have 56 as an option.

 

[mmi]

Well. Then just untick the 5F

 

[Mister-E]

Well. Then just untick the 5F

Done that and course the error no longer comes up, thank you. Now just left with the one fault. Probably nothing to worry about but would love to know/understand what is causing it.

Excellent result! Thank you for the feedback!

Now just left with the one fault. Probably nothing to worry about but would love to know/understand what is causing it.

I'm afraid the fault will be there forever. The A/C obviously expects to have some communication with Radio/Infotainment which currently doesn't happen.
Please keep eye on "Fault frequency" - to see if it steps up along with ignition cycles. Just curious to know....

The priority "6" of the fault is very low thus no action required.

Yes that's what I thought in regards to the level, so not worried. Thanks for your help.
