2018 VW Tiguan DSG jerks when cold – normal or am I in trouble?

I've got a 2018 Tiguan with about 85,000 kilometers on it, and for the past few months the DSG transmission has been acting strange when the car is cold. The first few shifts of the day are jerky, especially from first to second gear, and sometimes I feel a slight hesitation when I pull away from a stop. Once the car warms up after maybe ten minutes, it smooths out and drives fine. I took it to a general garage and they said the transmission fluid looks okay but they don't really work on DSG units. I've been reading online and some people say this is normal for dual clutch transmissions, while others say it's a sign of mechatronic unit failure which is expensive. I don't want to just ignore it and end up stranded. A coworker who drives a Golf R told me about a sharjah volkswagen gearbox service  that specializes in DSG repairs and can do a proper diagnostic including clutch adaptation and checking the pressure valves. Has anyone here used a specialist in Sharjah for DSG issues? I'm trying to figure out if I should just do a fluid and filter change first to see if that helps, or if I should go straight to a diagnostic. The dealer quoted me 1,200 dirhams just to scan the transmission which seems crazy. Any advice from VW owners who've dealt with DSG hesitation would be greatly appreciated. Thanks.
