Who makes the clutch? Where was the work done, if you don't mind me asking? Hyundai Ioniq 5 Ultimate. The family car.
2009 Rimini Red SE TD4. Gone.
2006 Tonga Green i6 HSE. Gone.
Audi A5 convertible, my daily driver.
1972 Hillman Avenger GT, the project.

Problem wasn't an issue before new clutch and flywheel fitted, it is a problem now, garage admit it's an issue.
Garage needs to change clutch and flywheel again at no further cost to you. Landrover - turning owners into mechanics since 1948

2014 Orkney grey Freelander SD4 GS.
2004 Zambezi silver Discovery 2 Td5 (Gone)
1963 Surf blue Morris Mini Minor Super de Luxe (my little toy)

Luckily I have a good relationship with the garage and they've always been very quick to address any of their faults. Yes, this may be a bigger issue to locate and deal with but I will be going back to them with the even stronger conviction that the problem does lie with the new clutch. Many thanks to all.
