The engine had been "harsh" over the last few months and sometimes the yellow engine malfunction light would come on and the car would enter limp mode, solved by switching the ignition off and then on again. This got worse so we investigated to find the problem was caused by the timing activators. We replaced 2 and the engine returned to health!
