I also have this problem with a 1.5 Petrol manual Taroq purchased in July 2018 with extra 5 year warranty which we have used mainly for long journeys, holidays in France and to visit family in London and Cornwall ( from Bristol).
In Oct 2019 the car started to smell after a short journey having done 8508 miles so I too took it to Skoda dealer and reported strong smell within cabin and no change in performance. The technician reported that nothing wrong with clutch or performance so must be way we drive. On collecting car from the dealer the smell did not reoccur again although they say they did not do anything to the car.
Last week my wife was driving and having just entered a busy dual carriageway ring road she tried to change up but could not do so the AA confirmed that Clutch had burnt out with 11107 miles on clock. AA transported it to dealer who investigated and said that need to replace clutch and flywheel but found nothing wrong with clutch so must be the way we drive therefore not covered by warranty. We have driven Skodas from 2002 and had no clutch problems plus our main use cars Ford and the Kia had clutch changed at 150000 and 79187 miles respectively.
When questioned they say that these clutches are hydraulic so cannot be adjusted, if so where is the slave cylinder positioned, should they be bled at service and where is the fluid reservoir as there is no mention of it in the Owner's Manual?.
Also how have all the other owners resolved this problem and is the Motor Ombudsman independent are set up by these dealers?.
