Hi,

 

Does anyone have any issues the petrol particulate filter thats in thr newer petrol focus or other petrol cars.  I read an old thread about warning lights been thrown up like dpfs saying the filter is nearly blocked and recommended to take them on motorways ect to clear them

 

Thanks

I've not had any warnings with my 1.5 Petrol car in the 3 years that I have owned it.

Some owners of the 1.0 engined cars do seem to have problems. It is a completely different engine though, not just a smaller one. Whether they are inherently more prone to getting clogged or the owners tend to drive in a different way I don't know.

If you do get one then the best advice is to drive it the way it was designed to and don't break into a cold sweat if the revs go over 2000 rpm. There needs to be a certain amount of heat going down the exhaust for the filter to passively regenerate, more than you would need for a Diesel car.

I have done some Live Monitoring of the Implied Soot Loads on mine and after a week of short town driving my Implied Soot Loads can go up into the high teens, but after a twenty minute run down the Motorway they normally go back to zero.

As far as I know that is all done passively through the way that I drive, I have never to my knowledge had an Active Regeneration.

Hi John,

Thanks for the reply and information very good to hear. Hopefully they dobt become as troublesome as the dpfs in deisels that were forced into motorways to clear them because the hole idea of small petrols for people are short stop start driving.

To be clear, if a car is only used around town or for short and stop start driving then the Temperature Gauge in the cabin may get up to normal but the Exhaust and GPF is unlikely to get hot enough and it will clog up.

If you stick around this Forum in the winter there will be lots of people complaining about their GPF.

Engine Emission Control - Gasoline Particulate Filter

GASOLINE PARTICULATE FILTER



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.
• 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.

Gasoline Particulate Filter Information Messages

 

Message	Action
Exhaust Filter at Limit Drive to Clean Now	Drive at a varied range of conditions, including highway conditions for 20 minutes or until the message disappears. Avoid prolonged engine idling. Select a suitable gear to maintain engine speed between 1500 and 4000 RPM.
Exhaust Filter Over Limit Service Now	Drive at a moderate speed. Avoid heavy acceleration and deceleration. Have your vehicle checked as soon as possible.

So basicly we are going to be i  the same situation as having a deisel woth a dpf having to run it weekly to make sure it doesn't block up if we do shirt trips. So people that have small cars for school runs or to get to mass and the shops are going to be up against issues like people with deisels . I wonder how long it will take for company's to start gutting them and a software update like the dpfs so people wont have these issues 🙄 id imagine there is a huge percentage of cars on the roads now with dpfs deleted due to them blocking up on people and the easier option is take them out regardless of how iligal it is and known they still pass mots/ncts.  I do see allot of exausts on deisels full of the black smoke in and  around it which tells there all gutted . I rememeber going looking at a car a few years back to a back street garage and it was the first thing I looked at and there were quite a few like that .

I don't know how effective the Active Regeneration is on GPF cars but I would imagine that if a car only does one or two miles most of the time then we are pretty much stuffed unless manufacturers have tweaked things since they were first introduced.

I must admit that when I found out my car had a GPF I was concerned but in my case there has not been a problem.

During the winter before last there were a lot of posts on here from people with the 1.0 engine complaining about the Drive to Clear warning, less so last winter. I don't know if that was because there had been software updates or because last winter was very mild.

I can only speak from personal experience, some other owners may have their own thoughts and post them.

My milage to work would be 4 miles to and then 4 miles back so I'd imagine I'd need to run it up a motorway on a weekend to be safe. Looking here there are plenty 1.0ltr focus for sale but no 1.5lt.  Personally I'd prefer the 4 cylinder 1.5 ltr as I'm sure its a stronger engine and has more power to pull a heavier car around putting less stress on the engine ect. But it seems to be the way they are all going 3 cylinder 1.0 ltr petrol engines on big enough cars. I parked beside a blue 2021 Ford focus st line today and I was amazed how stunning and neat looking it was .

4 miles id not too bad. Incidentally the 1.5 engines in the Mk4 Focus are the new 3 Cylinder Dragon engines. Loads more power and Torque than the 1.0 Fox engines and the difference in fuel consumption is small. You don't see a lot of them for sale though.
