Audi A6 Particulate Filter warning light
The particulate filter warning light came on two days ago. I read the manual which suggested running the car in fourth or fifth above 2000rpm for 15 minutes and the light should clear. Tried this with no joy. I'm not sure how long I can go on trying to do longish runs to 'clear' the fault without causing more serious damage.
I alternate between supermarket fuel and BP. Would regular use of fuel additive help. If so any recommendations as to which to use please? And any suggestions as to how to clear the problem please? Thanks

If you are worried, get it to the dealer for a forced regeneration. If the DPF is too blocked, then extra fuel injected to the engine to regenerate it can sink to the sump, raising the sump level until the engine runs uncontrollably on its sump oil and blows up.

My engine managment light as come on in my car and it says on my dash "antipollution fault." It's a Peugeot 307.
The diesel particulate filter (DPF) light is coming on in the dash but there appears to no DPF fitted.
Why is DPF light coming on?
Flashing DPF dasboard light came on at 23400 miles on 15/02/12. Mazda dealer diagnostic check showed that they had not reset the car computer(?) after the service in July 11, no actual fault with DPF....
