P1920 Volkswagen Code - Engine Mounting Control Solenoid Open Circuit / Short To Ground

P1920 indicates an issue with the Engine Mounting Control Solenoid, specifically an open circuit or a short to ground.

Symptoms may include increased engine vibrations, poor ride comfort, or a check engine light.

Possible causes include damaged wiring, a faulty engine mount solenoid, poor electrical connections, or a malfunctioning engine control module (ECM).

Inspect the wiring and connectors for damage or corrosion, test the solenoid for proper continuity, and use a multimeter to check for shorts to ground.

While the car may still be drivable, ignoring the issue can lead to increased engine vibrations and potential damage to other components.

Repairs typically involve fixing or replacing damaged wiring, connectors, or the engine mount solenoid itself. In rare cases, the ECM might need reprogramming or replacement.

Repair costs can vary but typically range from $100 to $300, depending on whether it's a wiring repair or solenoid replacement.

A weak or failing battery can sometimes cause electrical issues, but it is not a common cause for this specific code.

Clearing the code without addressing the root cause will only temporarily turn off the check engine light, and the issue is likely to return.

Yes, if you have basic automotive electrical knowledge and tools like a multimeter, you can inspect and repair wiring or replace the solenoid. However, professional diagnosis is recommended if you're unsure.
