Skoda Yeti will not change gear when engine is on

[MissChief]

And yes, I'm aware that the cost is excessive.

I would absolutely be looking for some sort of goodwill, if it wasn’t used, and the dealer will have noted the mileage and I’m sure will know exactly what was done, if they had or did anything whatsoever regarding the clutch then I’d be speaking to the dealer. Seems highly coincidental.

Any suggestions on lines to use?

are they saying fluid has been lost from slave cyclinder - maybe they got it wrong, interesting history

My problems started when I was doing fast gearchanges during full throttle runs testing the results after re-mapping during which time the DPF was throwing off loads of heat.

They returned with the new cylinder when doing the same thing, then after re-bleeding etc and driving normally it behaved and the problem returned with the warm weather, it is not present today at 5°C.

Having looked back through historic threads on here and other Skoda forums I see a lot of people have had the problem but never found the cause because the dealer had replaced everything either all in one go or on a parts bingo basis, master cylinder, bleed block, slave cylinder but also rushing them for a new clutch and dual mass flywheel for the latter.

I will be changing my clutch, DMF and concentric slave cylinder next week, after 3 months of trying everything to avoid pulling the 4wd transmission unit out I no longer have a choice as I have to bleed the clutch after every short trip into town, a 100 mile round trip involved losing the clutch on the way & having to bleed it, the same on arriving at the destination and once again during the return leg.
