Engine MIL illuminated – Peugeot RCZ
A customer of ours has a 2013 Peugeot RCZ and they are complaining of a lack of power, poor starting and the engine malfunction indicator lamp (MIL) is illuminated. There are trouble codes stored relating to the variable valve lift system.
The symptoms you describe are known to affect the RCZ with EP6CDTR (5FG) engine code and are due to damage of the variable valve lift shaft drive gear. Check the condition of the variable valve lift actuator, and replace if necessary. Inspect the variable valve lift shaft drive gear for damage (see Fig 2.1). If damage has occurred to the variable valve lift shaft drive gear, a new cylinder head is required to rectify this fault.
