A3 Mark

Thank you.. great to know what has happened and what needs fixing. Much appreciated 👍 M

Thank you, yes agreed it's probably a clutch or brake master cylinder problem. Was keen to see if someone else has suffered from this and how the problem was fixed. It's very strange behaviour.

Hi, Yes it's a common reservoir on the car.

Hi, first post on here - hope you can help me diagnose whats going on with my daughters A3 - its a 2014 2.0 TDI. It had a clutch change back in August due to failing slave cylinder and all was good. However when driving it this week the clutch pedal is doing something odd. It not returning after the clutch pedal is pressed - this happens quite often - not every time I press the clutch - but certainly on every journey. And if I drive the car after braking from say 40-20mph a couple of times then the clutch pedal will move downwards when I press lightly on the brake pedal - but not touching the clutch pedal. I'm trying to figure if the clutch master cylinder is at fault or if its the brake master cylinder. Brake pedal feels ok - not spongy. Any recommendations appreciated Thanks M
