P054B MINI Code - Cold Start Exhaust 'B' Camshaft Position Timing Over-Retarded Bank 1

Quick Answer

The Powertrain Control Module (PCM) monitors the Variable Camshaft Timing (VCT) position for an over-advanced camshaft timing during cold start up. Common causes include Camshaft timing incorrectly set, Continuous oil flow to the Variable Camshaft Timing (VCT) piston chamber, VCT solenoid valve stuck open. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
