🔌 Function

Controls the flow through its circuit on engines fitted with the compression brake, opening and closing on the control signal it receives.

⚠️ Common Signs of Failure

• Compression brake weak, slow to come in or not working at all
• Braking effect on some cylinders only, heard as an uneven note
• Fault codes logged against the valve or its circuit
• Valve found sticking or seized with varnish and debris
• Weeping around the valve body or its seals

🛠️ Service Notes

• Check oil condition, supply pressure and the electrical feed before condemning the valve - dirty oil sticks these open or shut
• A second control valve, 23509305, is listed against the same six TAD and TWD engines at 0.286 kg, so check the number rather than assuming either will do
• Renew the seals and any single-use fixings when the valve is refitted
