I have been following this thread closely as had loads of issues with popping and SOS warnings on my Mk4. Everything that can be replaced has been by the dealer but still getting pops and the odd SOS warning…I pushed them to do a full software update and they have assured me I am on the latest version 1941 (I know 1969 is now here) however if I check System Information software says 1668 but go into the engineering mode it says 1941…dealer says that I am on 1941 and 1668 is the “interface” version…I am not convinced. Anyone else have this issue? Never had any OTA updates or anything since purchased in November which makes me think there is a glitch somewhere.
