Audi adieu

Thank you for taking the time to clear up.

Thanks Steve Can I ask where you got this info from ? when I googled what gas it said r134a in a 66 plate ? It would explain why there is no plate information saying what gas it is in the car though.

Hi, new member here. I’m having an issue connecting to the low pressure port on my 2016 A3. Having delved around the internet it seems I might need some sort of adapter ? My 134a gauges fit fine to an seat Leon but they simply won’t stay on to the port in the Leon. Anyone else topped up their ac themselves ? TIA
