Hi all,

70k km Grand C-max 2019 1.0 EcoBoost, getting this message for the last week or so, comes and go after I drive for 10-15minutes, does it need a much longer drive to clean filter or something else to be checked?

I dont drive the car everyday and only do short trips most of the time (5-15 minutes several times a week). 

Thanks,

anything you do is going to be purely short term, the cause is lack of use. 

 

the vehichle needs to do longer runs. 5-15 mins isnt even getting the car to normal running temp. never mind burning off any accumulation in the exhaust system. 

 

the car simply isnt suitable for your needs, unless you are able to take it out every weekend for a good run. 

 

if you are insitant on keeping the car and cant change your routine, you can find someone to remove, and map out the filter. but then you risk failing emmisions test and mots. 

Change gear a bit later, that will help you.

Revs clean the filter out not miles

Run on E5 too, it will run cleaner and soot up less

Sounds just like the thing a Ford Model: Zeroy  would need 🤣

Do what is says in your Handbook.

A GPF is different from a DPF, it needs the extra heat you get when driven hard but also the Oxygen that you get when taking your foot of the Gas so you need to rev it high and you will get the Oxygen when taking your foot off. Diesels run with excess Oxygen so they Regenerate differently.

Driving like your Granny is in the back will not do that and don't over rev it until it's up to temperature.

Gasoline Particulate Filter - 1.0L EcoBoost™



WARNING:  Do not park or idle your vehicle over dry leaves, dry grass or other combustible materials. The regeneration process creates very high exhaust gas temperatures and the exhaust will radiate a considerable amount of heat during and after regeneration and after you have switched the engine off. This is a potential fire hazard.

To reduce the risk of causing damage to the gasoline particulate filter:

• Do not crank the engine for more than 10 seconds at a time.
• Do not push-start or tow-start your vehicle. Use booster cables.See  Jump Starting the Vehicle . 
• Do not switch the ignition off when your vehicle is moving.
• Do not ignore warning lamps, indicators or information messages.

Gasoline Particulate Filter Regeneration

Particles in the exhaust gas collect in the gasoline particulate filter causing a gradual restriction over time. This restriction is removed through a regeneration process controlled by the engine control system. The regeneration process converts the particles in the exhaust gas into harmless gases.

Regeneration occurs during normal driving, to varying degrees depending on how you drive. Passive regeneration occurs when you drive at moderate to high speed but if you generally drive short distances at low speed, the engine control system could actively raise the exhaust gas temperature to remove the particles that have collected in the filter to make sure that it continues to correctly operate.

To assist passive regeneration, we recommend that you make occasional journeys that allow you to:

• Drive at a varied range of conditions, including highway conditions for a minimum of 20 minutes.
• Avoid prolonged engine idling.
• Select a suitable gear to maintain engine speed between 1500 and 4000 RPM.

If the filter is saturated or is approaching saturation, a warning lamp illuminates or a message appears in the information display.

Note:   A warning lamp illuminates and a message appears in the information display on some vehicles.

If you do not take action when a warning lamp illuminates or a message appears in the information display, you could cause damage not covered by the vehicle Warranty.
