I have a 5 year old Lexus 220d. It's low mileage (50k). It's developed a squeak/creak noise on the clutch when the pedal in pressed down. It was originally doing it when it was cold, it's now doing it warm too. It sounds like a creaky spring. Any ideas on what is causing it? If it's a big job the car's going - I've had enough of expensive problems with this car!
