Could this be the same issue? I was driving for a couple of hours, first timer on the Autobahn so between 130-145 km/h, full blast aircon for a few minutes and then just on number 1 (simple system, no climatronic).
I noticed clear water dripping when we stopped, under the passenger seat. Then when I drove off the orange warning light came on, advising me to search for a garage…
I’m in Berlin right now, not really keen for a visit to a foreign dealer. Car drove the rest of the trip (+300 km) just fine.
If it’s condensation then the warning light should be activated by something else I presume?
Some condensation dripping is normal, but your warning light needs attention I fear. Can you call VW assist? That would remove the need to go looking for a garage initially.
