Mercedes Engine Brake Repair

One of our sports run buses has an engine hold back problem when coasting down hill. The Mercedes MBE 900 has an exhaust brake and an engine brake. Used together they really work well and you can feel it while driving. The engine brake is called a “Constant Throttle Valve” or “CTV”. The valve itself looks like a regular engine valve but much smaller that opens on demand using engine oil pressure supplied by the CTV solenoid.
