Brake Servo Change Over Valve. Porsche 970 Panamera 3.0L Diesel 2009-16 ❭ 97060512300
- Porsche 970.1 Panamera Diesel V6 3.0L 2011-13
- Porsche 970.2 Panamera Diesel V6 3.0L (250Hp) 2014-16
The Genuine Porsche Brake Servo Change Over Valve is an original equipment braking system component designed to regulate and control the vacuum supply to the brake servo on compatible Porsche models. Manufactured to Porsche's exact specifications for fit, performance and durability, this precision-engineered valve ensures the brake booster receives the correct vacuum assistance, providing consistent brake pedal feel and optimum braking performance under all driving conditions.
Fits:
- Porsche 970.1 Panamera Diesel V6 3.0L 2011-13
- Porsche 970.2 Panamera Diesel V6 3.0L (250Hp) 2014-16
Diagram Ref No 22
Manufactured from high-quality automotive-grade composite materials with precision-engineered internal valve mechanisms and durable sealing components, the brake servo change over valve is built to withstand continual vacuum cycling, engine heat and prolonged exposure to the engine bay environment. Designed as a direct replacement for the original component, it integrates seamlessly with the vehicle's vacuum and braking systems to maintain factory-correct operation and reliability.
What This Product Does:
- Regulates the vacuum supply to the brake servo.
- Maintains consistent brake booster assistance.
- Supports optimum brake pedal feel and response.
- Helps ensure efficient brake servo operation.
- Controls vacuum flow within the braking system.
- Assists reliable braking performance under varying engine conditions.
- Restores factory braking system functionality.
- Forms an essential part of the brake servo vacuum system.
Symptoms Of Wear Or Failure:
- Hard or heavy brake pedal.
- Reduced brake servo assistance.
- Inconsistent brake pedal feel.
- Hissing noise caused by a vacuum leak.
- Illuminated brake system or engine management warning light.
- Vacuum-related fault codes.
- Increased stopping effort.
- Poor brake response during repeated braking.
- Engine idle irregularities caused by vacuum leaks.
- Visible damage or deterioration of the valve housing.
Why Replacement Matters:
- The brake servo change over valve is continually subjected to engine vacuum, pressure fluctuations, heat and repeated operating cycles. Over time, the internal valve mechanism and seals can wear or become contaminated, reducing their ability to regulate vacuum correctly or causing vacuum leaks.
- A faulty valve can reduce brake servo assistance, resulting in a harder brake pedal and increased effort required to stop the vehicle. Vacuum leaks may also affect engine performance and trigger fault codes or warning lights. Continued operation with a defective valve can compromise braking performance and driver confidence.
- Replacing a worn or faulty brake servo change over valve with a Genuine Porsche component restores correct vacuum control and brake servo operation. Manufactured to Porsche's exact engineering standards, the Genuine Brake Servo Change Over Valve provides precise fitment, reliable performance and long-lasting durability, helping maintain the safety, braking efficiency and refinement expected from your Porsche.

DOT 4
Having an extremely high boiling point and lower viscosity than required, it meets and greatly exceeds regulatory standards. Also suitable for vehicles with ABS.
Vapour Lock formation
This sort of habit leaves room for the Vapour Lock, the formation of vapour bubbles due to boiling of the brake fluid that replace the normal fluid and are compressed, thereby sending the brake pedal to its fill stoke (spongy pedal). The origin is incident in the porosity of the tubes that make up the braking circuit, which in time draw moisture into the fluid, drastically reducing the boiling point. The result is a reduced braking efficiency.
Brembo Premium Brake Fluid
Brembo Premium brake fluids have a higher boiling point that exceeds the standard, thus offering superior resistance to the Vapour Lock and ensuring braking efficiency even at low temperatures. With high anti-corrosion properties and resistance to oxidation, Brembo brake fluid also allows for long-term unaltered chemical/physical characteristics of the fluid in operating circuit; therefore, preserving its integrity.

Brake fluid is one of the most important fluids in a car as without it, stopping the vehicle safely would be impossible. The Brake fluid transmits the force exerted by the driver on the brake pedal onto the wheel brake.
To ensure perfect operation of the brakes, the brake fluid must be changed regularly during inspection or maintenance and tested with the correct brake fluid tester.
Brake fluid should be changed every two years.
The higher the DOT class, the higher the boiling temperature and wet boiling point. Higher DOT classes tend to allow longer maintenance intervals. The DOT standards are based on the American FMVSS-116 standard of the Department of Transportation (DOT).
Boiling Point and Viscosity
Dry Boiling Point - describes the property of the sealed new brake fluid. In this state, the brake fluid is almost anhydrous (substance containing no water). The dry boiling point is usually between 240 and 280°C.
Wet Boiling Point - determines the property of the brake fluid at the end of its life cycle, at a water content of 3.5% the fluid should be replaced. This defined wet boiling point must not be undercut.
Viscosity - describes the flow rate of the brake fluid. The lower the viscosity, the faster the brake fluid flows through the brake system, and the faster the brake signals are transmitted.
Important Notes
• Brake fluid is poisonous and a hazardous waste.
• Be careful when changing. The fluid weakens paints and plastics.
• It must not come into contact with eyes or skin. Always rinse spilled liquid with water.
• Do not pour the liquid into drinking water or mix with used oil.
• The colour of the brake fluid reveals nothing about its quality.
• Brake fluid should be stored in its original packaging and in a dry, cool and well-ventilated place.
