1.5 Tsi Power Cutting Out

Missph
in Skoda Karoq

Featured Replies

The 1.5 TSI is a Miller cycle engine rather than the traditional Otto cycle. It relies on precise engineering tolerances. This problem doesn’t seem to affect all manual 1.5 TSI Karoqs nor does it seem to affect DSG versions. It also seems to affect vehicles that are brand new so that would rule out lack of maintenance. What do people think about this : that small number of engines might have critical components and sensors which individually are within tolerance but the collectively the tolerances are not really matched. Statistically this is a possibility. Thus leading to the engine software being unable to manage the engine in certain specific instances. The engine management software and DSG control software obviously communicate with each other and possibly pre-empt the stall or cutting out and change down or disengage the clutch. Just a thought.

      Almost all of us reporting this problem seem to have a mid to late 2023 or 2024 1.5TSI manual Karoq, so this will be the evo2 engine, ie new version without the engine cover. So I think Bigjohn may be

      Although I have had my Karoq for 9 months, I have only had this engine cutting out problem on three occasions. The first two happened while I was talking to others in the car and the engine cut out as
