i have a error i can not get to the bottom of, maybe someone can throw some light on it,
error p2527 exhaust gas recirculation positioner or component short or open circuit, i have replaced erg switch y27, andstill error checked pin 1 and pin 2 and i have 12 volts, as mb star says i should have,
i think maybe someone has connected the vacuum pipes up on both the switch over valves incorrectly, any one have a good photo of there correct connections, thanks
