I have a stock 2020 gli. Well, it’s my wife’s but u know what I meanVW said 502 oil for my 18 SE and at 1000 miles changed the oil and never used 502 once since then. 131,000 heavily tuned miles later and going strong.
last oil change I poured in the vw502 5w40. All was fine. After the 24fx update, the car sounds and feels like it wants to stall during cold start. And for some weird reason her oil temps average about 10-15f higher than mine. Before 24fx my oil temps were about 5-10f higher than hers.
I think 24fx introduces an actual need to use the 0w20
