but surely if the EGR was faulty the car would be playing up in some form or other - the car runs sweet, starting, accn, etc etc. Passed the MOT with flying colours including emmisions... | |

When they clear the code the light goes out for 30 secs (or so) then code comes back and then light comes back on. | |

So - I've changed the EGR with an EGR that was 2nd hand but guaranteed to be working BUT ECU light is still on. Paid for the Tech 2 to be plugged in again to see if the fault had to be cleared through this (having been unable to clear it through >30 cold starts and having disconnected the battery several times and for several days) and..... the Tech 2 now reports "P1405 EGR Valve Feedback Incorrect". | |

That 30 on/off - is that just turning the ignition on and off rather than starting the car 30 times? | |

quote: But on later systems you cant clear the code by disconnecting the battery. :thumbs: Some say 30 ignition on and off's do it, but it doesn't on mine. Apparently a set number of cold starts are needed without the fault occuring before the ecu clears it. | |

Can yo uclear it by disconnecting the battery for a period of time? OR do you need a diagnostic reader? | |

not always 100% ture, sometimes you need to clear the code before the EML goes out | |
