2017 T6 150 DSG Engine Control Module Error

[Gambler71]

My California is still in warranty until May 2020.

Last Monday I took my vehicle to the VW Van centre in Hereford for a full service (~12.5k miles on the clock),
my local van centre in Cheltenham closed a few months ago.
The only critical item was an upgrade/update to the ECM. Drove down to Plymouth on Wednesday evening,
approximately 160 miles or so and a couple of short trips around Plymouth. On Thursday afternoon the orange
engine light illuminated on the dash and remained on. Friday morning I drove out of town to Snows VW centre at
Plymouth with the aim of getting them to put it on the analyzer to check out any error. On the way out to Snows
the light went off, but I thought I would still get it checked out. Let's say Snows were less than helpful due to a
service manager with a very large ego. Why oh why is the first thing out of their mouths, "Well it must be your
driving style sir"? Just ignore the information I gave you on the service and the update to the control module.
Anyway, my experience at Snow's is probably a very long post in another thread.

Two questions please:

While my van is still under warranty, and in good faith I had taken the vehicle in due to the fact that the engine light had been on, the Service Manager threatened me with a bill of 90 odd pounds, + VAT, if the if they put the van on the analyzer and found no fault codes I would be liable. Is this really the case?

Arrived home this afternoon and looked at the codes with my obdeleven. Any ideas what this means below before I waste a couple of hours on the phone with VW on Monday?
