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

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."
