Been suffering from this for about 12 months now once a month but recently more like once a week on my 66 plate 2017 TDi VRS 35k miles. Started 2 services ago nothing picked up during last dealer service though. Thought it might be battery related as havent used her as much during lockdown and WFH most days. But yesterday morning I got an orange emissions light pop up that wouldn't disappear. Got my mate (The Engine Whisperer) to plug in his box of tricks and pulled up a glow plug issue on cylinder 1 fault. He reset the light and it hasn't come back on, but the car was warm so will see what happens in the morning when I turn her over and will give Skoda a shout to get her checked out....
