Common C2727 Misdiagnosis on the Rolls-royce Wraith
A catalytic converter is often condemned on the Rolls-royce Wraith when C2727 appears and an efficiency code is present. Before replacement, verify that the upstream oxygen sensor is not slow-responding — a lazy O2 sensor mimics catalytic inefficiency perfectly.
DIY Repair Guide: C2727 on Rolls-royce Wraith
Battery terminal cleaning on the Rolls-royce Wraith is a 5-minute job that resolves a surprising number of C2727 intermittents. Use a wire brush and a bicarbonate of soda solution to clean corrosion, then apply a thin coat of petroleum jelly to the terminals after refitting.
Preventing C2727 on the Rolls-royce Wraith
