Clutch Fluid: Service and Repair

Clutch system, bleeding

Special tools and equipment

- VAG1238B brake filling and bleeding appliance or
- VAG1869 brake filling and bleeding appliance

WARNING:

- Brake fluid is poisonous.
- It must NEVER be removed by siphoning with your mouth.
- If brake fluid contacts skin or eyes, flush or wash adequately to prevent irritation. Get medical attention immediately if necessary.
- Brake fluid must be disposed of properly.

CAUTION:

- Use only fresh brake fluid conforming to US standard FMVSS 116 DOT 4. Genuine VW/Audi brake fluid conforms to this specification.
- Brake fluid must never be brought into contact with liquids containing mineral oil (gasoline, cleaning agents). Mineral oil damages the pistons and cups in the braking system.
- Brake fluid must not be allowed to come into contact with paintwork because of its caustic effect.
- Brake fluid is hydroscopic (i.e. it absorbs moisture from the surrounding air) and should therefore always be kept in airtight containers.
- When carrying out the steps, make sure that no brake fluid escapes onto the transmission.

- The clutch system must be bled after carrying out work on the hydraulic clutch mechanism.
- Top-off brake fluid reservoir to "max." marking with brake fluid before bleeding clutch system.
