    Default Has Anyone Actually been Visually warned that a DPF Regen is Taking place & Completed

    How many drivers of Diesel Particulate fitted cars have actually been warned & seen the Visual warning (Glow Plug Light) on the dash illuminate & then extinguish once complete. ??.

    As per Handbook " Flashing, Dpf requires cleaning, As soon as traffic permits, Increase speed to more than 25 Mph for a brief period, The indicator extinguishes once complete"

    Now i have had the latest Regen software under the recall & i have never seen the glow plug light illuminate/flash, But it has done a regen, Noted by the heat & smell of the exhaust, Smoke & 0.9 Mpg economy at Tickover.

    Mine just seems to illuminate the Car with the spanner through it at startup & then goes out once running

    Another forum users input on the latest update software

    "
    Regeneration is the process which produces a high temperature in the Diesel Partical Filter to effectively “burn off” the soot particles. Achievement of the required DPF temperatures requires the engine to be operating at sufficient speed and load conditions to trigger and sustain the process. Generally the vehicle needs to be driven at a speed of 25 to 30 mph or more for a period of approximately 15 minutes to complete regeneration. Providing these driving conditions are achieved on a regular basis, DPF regeneration will be triggered automatically with no further intervention required. Some types of use, e.g. short urban journeys, do not allow complete automatic regeneration to take place.
    In this instance the driver should ensure that the vehicle is driven regularly within the required regeneration parameters for a short period.

    Vauxhall / Opel (1.9 Diesel)

    An optimised soot loading model for the DPF has been developed to initiate automatic DPF regeneration at a lower level of soot loading of the DPF.
    This reduces the likelihood of complete DPF clogging.
    Additionally, the impact of an aborted regeneration (driver switches off engine before regeneration completion) is reduced.
    Should the lower soot loading threshold be reached, the driver will now receive warning that a regeneration is required viaflashing of the instrument glow plug light. This will enable the driver to initiate a regeneration by driving to the required parameters when road and traffic conditions permit.

    Failure to achieve an automatic regeneration will lead to clogging of the DPF. If this occurs, the engine warning light will illuminate and the engine electronics will switch to the emergency running programme.
    The DPF will require a manual regeneration which can only be initiated by a Vauxhall Authorised Repairer."

    Thoroughly confused

    Nope. not once in 6 months and not far off 13000 miles.

    Mind you, mine's not a town car, so it might not be needing a regen quite so often.

    My car does do short journeys each day, 8 miles to work & 8 back Etc, But more miles at the weekend.

    This Car & Spanner light may well be a red herring, Although there are no fault codes stored, It does say Emmissons Control..

    Tonight the Car & spanner illuminated but still no regen like before.

    Perhaps the Ecu does need to be read by a vauxhall Specific reader to get the full picture ! But im concerned that i will be paying for a code read only to be told, " Nothing Stored Sir"

    Im also having the Car remapped tomorrow & did not want to have to go back to Vauxhall & for them to over write the map

    Never seen an indication in 21,000 miles except for as you say, smell & increased fuel consumption

    Spoke to a different chap today at Vauxhall & apparently the visual display that a regen is taking place has been removed. To many people were going to the dealerships complaining of an error/fault, Light displaying Etc.

    Personally, I would rather be aware of a Regen taking place & stopping Etc, It helps with preventitive maintenance, i.e keeping driving whilst it is in progress to enable it to complete properly !!!

    A backward step in my book

    But with the amount of people not reading the manual, I bet they had thousands asking what the light was, I think they made the right decision, although I understand your point.
    Now I need a turbo to keep up!
