advance corrector - loity
I own a 1998 Peugeot turbo diesel and my brother owns a 1994 Peugeot turbo diesel both are fitted with lucas fuel pumps. On a schematic diagram for the electrics mine shows advance correction solenoid and advance correction relay, however on my brothers it shows advance corrrector/fuel cut off solenoid and advance corretor relay. Despite this both our fuel pumps look similar. What is the purpose of the advance corrector, how does it work? Is it something to do with the fast idle on a cold start or perhaps is it connected to to the post heat time out circuit? Please could someone enlighten me.

I believe it is used to alter the injection timing when cold starting.
I have a 1995 Peugeot 405 TD. The Haynes manual schematic shows an advance corrector relay and solenoid, but the Bosch fuel pump in fact only has a fuel cut off solenoid fitted. It starts and runs just fine when cold, so the advance corrector is obviously not necessary on this engine.
