The engine idle revs on my Peugeot 306 can vary from 700 rpm to 2400 rpm without any driver intervention. The idle regulator has been replaced but this was to stop the engine cutting out when dipping the clutch. The local Peugeot agents are unable to solve the problem, having had the car back half a dozen times. The engine management warning light comes on for prolongued periods when traveling more than a mile. Any one want to buy a pup? Or any suggestions how to cure. Thanks in advance
It now transpires that there are a multitude of people with ECU problems in 206's, and 307's as well as my own experience in a 306. It appears to be a universal ECU problem in cars less than 5 years old and Peugeot are continuing to deny responsibility or to fix with a re-call. Be warned.
