Managed to get out for a good motorway run and it actively regened down to 2.5g soot mass.

| That's my video and it only started sounding like that after an EGR delete. If the car is a new purchase then I would suspect that it may have had an EGR delete? |

Thanks, appreciate the update. Very interested to hear your outcome.
I'll write up more when I have the time, but I'm increasingly thinking that my remap isn't the best quality and perhaps an examp ... |

| I did wonder if that was the case initially, perhaps I read something along those lines. I have a blanking plate installed so I could remove that and see if there is a difference as the EGR valve does ... |

Had a chance to try the TPS reset today and have to say thanks, as that worked a treat. Only concern now is that I have to be careful to not speed.
Had to take the wife out to get some bits this m ... |

| I've definitely noticed some mpg changes. At some point I prior to the egr delete I must have reset the trip computer without realising, and at that point it was about 22mpg over the past 500 miles, w ... |

I’ve gone through that entire thread nearly twice now, so I’m probably as familiar with it as anyone could be without having contributed.
The reason I’m posting in this thread is that my carâ ... |

Thanks Aviator, that's very interesting to know.
I'm curious as to what the active regen behaviour is like with the EGR delete. I've only had the initial one which was immediately after the remap, ... |

Was this an active regen (started by the car) or did you do a forced regen via the gap iid, Aviator?
I find with mine that soot mass does seem to be dictated mostly by engine load. If I'm going up ... |

Hi All,
It was the cable/socket. I found two cables that clicked home more firmly and the IID was found on port 5. Possibly some usb cables were power only.
The update routine said to update t ... |
