It's getting towed to VW tomorrow so hopefully will find out the issue soon.

Took it in for diagnostics at £75 - no fault found to explain the clutch. A leak was suspected despite reservoir levels being within limits, however no leaked fluid could be identified on any of the components.

A further hydraulic test was then advised and undertake (£105) to check for any leaks. Still no evidence found.

The next step suggested was to replace the slave or master cylinder. They have suggested replacing the cheapest first for which (over the phone) I was quoted £500 in total. They said that the other would need to be replaced if not as they could not tell which if any was faulty.

What causes these to fail at such low milage (I saw multiple cases listed on the car's review page at criminally low milage)? Should the dash indicate such a fault when it occurs?

They have advised replacement of the Master Cylinder (without stating why). Everyone else I've asked seems to suggest problems with the Slave are more likely. I feel like I am facing the prospect of a huge bill with the potential for the fault not be fixed until all other possibilities are exhausted.

The experience has put me off VW completely. I never expected parts to fail so soon after the warranty had expired and at such low milage. I never questioned the reliability of their cars before but this is a hard and expensive lesson.

Unfortunately for me, easier and cheaper may be a false economy if it is less likely to fix the problem (I know John and others have suggested the Slave is more likely).

I have received the quote for the Slave cylinder replacement(£996).

However, the VW and the Master Technician has advised the Master cylinder be replaced first at a cost of £508. Hopefully this is based on my best interests and the likelihood of it fixing the problem.

As the clutch went during driving without warning it could have been quite dangerous so we really need this fixing properly. If it's likely to happen again, I will 100% be getting rid of the car.
