What a breath of fresh air actually watch someone with great insight and knowledge take a job on find the root problem and fix it properly there are too many guys out there with diagnostic devices just want to plug it in clear faults then hope its fixed when faced with a problem beyond their skill set want to throw their hands up in defeat well done lad another great educational video.

I hear ya.... respect to the technical minded amongst us. 👊

[@Bond2025]

*ALL* Vauxhall diesel cars sold in the UK from January 2013 to January 2014 had faulty DPFs fitted and should have been recalled. In mid-2013 there was a queue of 600+ people around the UK waiting up to 4 months for one and being given hire cars by main dealerships - paid for by Vauxhall/Opel. It was a really big problem. Then they lied about emissions and when cars went in to dealerships for services, they altered the software and forced regeneration every 300 miles to try and hide it.

For DIYers remove glow plugs with a torque wrench set to about 10 nm more than tightening torque, if it wont come out stop and soak with penetrating oil for a week and try again with a hot engine. If still stuck go seek an expert who can fix it when it snaps. You could also test braking point on a plug that did come out easy, and set wrench a bit lower

[@davidg.johnson7208]

I have a 2011 (diesal) Sprinter 3500 that I had the emission system replaced after a Mercedes Benz class action lawsuit/ recall a couple of years ago, so the DPF filter is practially new but I am at a Sprinter service center right now with emission problems; check engine light and limp mode. They plan to replace some sensors and the DPF filer. Waiting for Sorinter parts. I found out that you cannot let vehicles with DPF filters idle too long. The DOF needs the heat of long driving to burn off the carbon. Letting a cold diesel engine idle for too long will cause a lot of carbon to build up in your DPF filter!

[@karlburke276]

You forgot to mention it is always wise to do glow plugs on a hot engine, sometimes they seize in place and are a nightmare to remove if they snap in the head.

[@jamesieadams]

When I am diagnosing and cleaning DPF I go around saying every step in an Irish accent😂 Jimmy, thanks for the help! I love saying “manometer” with that beautiful accent!

Did whoever changed the DPF register the new one to the car iv learned so much from your videos great video glow plugs stress me out

[@MrZimmaframe]

Hey Jimmy you will have officially made your 1000th video in just 23 more uploads 😄, crazy. You should make a "Rise of the Soot Soldier" skit 😂, it would be so funny.

I've got a job monday for an acid clean on a car that's had a dpf delete . They complain of a smell . The interior reeks somthing chronic, i know that Its probably fuelling for a regen sometimes if the maps no good i reckon . Sounds like the sort of job to swerve . Ill send him to you 😂

[@islandhopperstuart]

Please can you explain the relationship between glow plugs and DPF blocking. Great video: thanks!

[@terford1995]

Not efficient burning of the Diesel and therefore more soot

[@timbo19751975]

​@@terford1995 what ????

[@timbo19751975]

The glow plugs are used to ignite the diesel thats injected late that generates the extra heat to regenerate the dpf

[@richiec9077]

The glow plugs are required in the regeneration process of the dpf, so if any of the glow plugs activate a fault code in the engine management system the car will then stop performing dpf regeneration. The dpf will become blocked if you keep driving the car with the fault code present and or the fault not rectified.

[@bigfilsing]

I too would like to know how he arrived at the conclusion the glow plugs were bad ?

[@Tony-fh2wi]

Jimmy the force regen is same mechanism on electronics of the won regen from the car, make regenerations with the car in place is the bad point, all force regenerations was to make driving at low speed, betwen 55 kmh to 60 kmh and > 2000 rpm. Gpod job!

[@guygfm4243]

Love the way you work, thanks for sharing.

[@ORileysAutos]

Thank you! Cheers!

[@donatas85]

Even without the glow plugs a regeneration on the highway with high RPM could have saved the old DPF filter and regenerate naturally (driving on high RPM like 3000). That is what I did. After that I changed all the glow plugs, because the regen in the city could not be properly performed because of one faulty glow plug (that is why my DPF got full in first place). And the funny thing is that most of the repair shops don't know that glow plugs in EURO 5 diesel are essential to DPF regen :D I almost have taken my car for DPF removal and reprogramming :D

[@ekimthims1]

Had forced regen done by garage on astra 2.0cdti to solve limp mode + service vehicle soon message.. result was a melted fuel tank because of heat..cost 400quid.

[@thindo]

As you just demonstrated I think it pays to ask the customer the history of the cars problems whereas probably the other mechanics just assume

[@williampatrickfagan7590]

I was under the when that GLOW plugs were only employed when the Engine was being started from COLD. THat USED to be the case when i was a young fella. HA that changed?

[@barryjackson8512]

DOF delete is the best thing for any diesel

[@09014791]

Hi Love your videos I have an issue on my van hoping you can advise as its back and forward to the main dealer and they just change the oil. Drives around 4000 - 8000 miles and goes into limp mode with code p119f - oil dilution showing at 10% diluted. It's a 20 plate Toyota proace 2.0 d4d and the dpf differential pressure is at 23 milibars at idle increasing drastically as the revs climb. This was extracted using autel scanner.

[@paultraynorbsc627]

Good shout on forced regen oil change oil dilution

[@steveguest8028]

Good video Jimmy

[@DjToxicCandy]

So does the auto or forced regen use the glow plugs to increase the combustion/exhaust temperature? If so I'm wondering if faulty glow plugs may affect the regen process and produce more soot?

[@richardmalone3172]

Another informative video. Thanks mate.

[@paultro8457]

Over here in the states I have a GM Buick Encore that is that exact vehicle. Haha Well, that one is diesel and mines gasoline. But the dash and everything else is the same. Not a bad little AWD suv. What make and model is the car you're working on?

[@ORileysAutos]

Vauxhall Mokka

[@Chris-q7c]

Why is there a need to change the oil after a forced regen? My Audi A6 does a regen every few hundred mile as described in the handbook for the car.

[@mattheww6167]

Another great video from a true professional! If i can ask a question I've recently purchased a 2013 VW Golf diesel, when i change the oil, do i need to re-set a service reminder? I've not had a vehicle with a DPF before. Many thanks

[@ORileysAutos]

Yes, absolutely

My Insignia is regenerating every few miles, however according to my launch diagnostic its not requesting one?

Why is forced regen worse than ecu regen? Is it because of no airflow around DPF shell

You'd need to check the pressure sensor circuit and pressure readings

Jimmy eco is for Aircon not stop start 😮😅

[@hadiamrane]

Yes it is. We have citroen that keeps blinking "eco" on the dash when we come to a stop and then the system activates and it keeps the "eco" light on. I'm pretty certain they use the same system as the PSA cars. Only PSA uses the term "eco", other cars use the logo with the letter "a" and a circle. Maybe look at the cars manual to have a better idea ;-)

[@MrAvant123]

To be honest if you NEED a forced regen you probably shouldnt have a diesel car in the first place, because your driving profile is wrong. I have a neighbour who was complaining about his diesel, but in reality he rarely does a journey above 10miles and mostly only potters around our country lanes. My diesel regularly gets subjected to 200 or 300 mile motorway thrashes !

[@ORileysAutos]

It's extremely rare I see a car that has actually driven so little it needs a genuine forced regen.

[@williampatrickfagan7590]

1/4 Inch ratchet tells you when to stop tightening, that and years of experience.

[@Bond2025]

Turn the auto-focus OFF and we will be able to see what you are filming without all the messing about. Don't forget you get TWO different types of GlowPlug for those engines, with and without a pressure sensor. The one with the pressure sensor is around £130+VAT in the UK. That's even more from a main dealer. The glowplugs do not just work to start the car, they activate when you change gear too, to burn off excess diesel and prevent a puff of smoke. The glowplugs ONLY need changing when the car shows the error message "SERVICE VEHICLE SOON". There is no error code for the glowplugs failing apart from this message, but the pressure sensor failing will show an error code.
