*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.
Props to the less knowledgeable mechanic for actually being honest with the customer and saying "I'm not sure what caused this to happen and you're better off seeing someone who's more knowledgeable on these issues". Too many "Self made" mechanics in a van think they know it all and will plow on charging the customer for investigating a fault they know nothing about. Great video. Just subscribed and look forward to more in depth videos in the future 👍
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.
Thank you
As a self employed mechanic your vlogs are a great source of info. And just goes to show cut corners you get burnt. Literally 🙄
Thanks
I hear ya.... respect to the technical minded amongst us. 👊
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!
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
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
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.
Just shows how complicated modern cars are
Thank you for your video
Guessing isn't an option anymore
Guessing can get expensive
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!
Wow what great knowledge, and explained in such a easy manner, hat off to you sir, we are humbled by your professional capabilities.
Thanks a ton
Love the way you work, thanks for sharing.
Thank you! Cheers!
Another informative video. Thanks mate.
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.
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.
Top job Jimmy 👍
Thank you
DOF delete is the best thing for any diesel
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
most mechanics are just fitters.. fit this and hope it fixes the problem)
You are a technician!
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
Good video Jimmy
Good shout on forced regen oil change oil dilution
Another great vid. 👍
Thanks again!
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.
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 😂
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?
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
Yes, absolutely
Hi what does it mean if your outside air temp is high ? Couldn’t find the video Tia
Hi there. I have an Audi A4 b6 1.9tdi 2003-2004 and have a dpt light on. Bought I launch 129 tool. Problem is it got a catalytic converter on a diesel engine not a DPF. What do I do?
Why do we have to change the oil after a forced regen?
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.
Please can you explain the relationship between glow plugs and DPF blocking. Great video: thanks!
Not efficient burning of the Diesel and therefore more soot
@@terford1995 what ????
The glow plugs are used to ignite the diesel thats injected late that generates the extra heat to regenerate the dpf
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.
I too would like to know how he arrived at the conclusion the glow plugs were bad ?
What sort of miles or Km on the cars look like these items. Could be changed bit earlier. People with vehicles in remote areas like outback Australia would service these items if they knew.
Why is forced regen worse than ecu regen? Is it because of no airflow around DPF shell
Of course the darn squirty can junk made it's way down the threads AS you Unscrewed it .
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?
Vauxhall Mokka
Wish you were in my region co durham england pissed off being stitched by so called mechanics still have my mokka in limp mode
Belta watch 👍👍👍
Thanks
Mine astra 1.7 cdti offten regenerate by her self ( every 40 to 60 km) . We put endoscope in dpf and dpf is white like brand new. What is the problem ?
You'd need to check the pressure sensor circuit and pressure readings
Tha cross a jaazus on it bays..
Zafira insignia astra mocha high fire risk.
What….?
At least the mechanic knew he was beat instead of just chucking more parts at it..
Yeah suppose. My 11 year old son could have diagnosed this though
@@ORileysAutos tbh I commented before watching the hole video stage why he couldn't diagnose the glow plugs and oil change.
I did you what you told me and put pat fluid however problem is still there any other ideas before i go mental and start spending thousands or a dpf delete
What codes are you getting?
Dare I ask, but how much is a new DPF ?
Hi, where are you based? I just bought 2011 sprinter 316 cdi automatic. Its due its service and would appreciate someone like yourself to do it. Thanks in advanced
Biggleswade
Gutted. Your 235 miles away. Thanks for getting back to me though 👍🏻
Jimmy eco is for Aircon not stop start 😮😅
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 ;-)
You can see on the rev counter though it's a stop start
I will have to pay tax on any payment received from server company. This adds another layer of complication when filing my tax return
wHERE DID YOU FIND OUT THAT IT WAS A FIRE RISK, DID YOU HAVE A FEW FIRES YOURSELF
General knowledge. Vauxhall are a bit famous for catching fire
Omega isn't that bad got a set of stubby ratchets actually no too bad tool probably better than lazer but maybe not sure
Dont get a diesel if not doing more than 12k a year or buy an old 1.9 pre 2009 passat golf or skoda pd and look after it will do starship miles. 😊 I had an old 1.7td astra isuzu engine bombproof not common rail but pre combustion chamber in head much better design I think.😊
its funny that vauxhalls dont like being cars these days ,the last decent vauxhall was the hsr chevette
Luuby..
Jasus mother Mary be wit us
Maybe you should do CZcams, we could take the Mick out of your accent too !
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 !
It's extremely rare I see a car that has actually driven so little it needs a genuine forced regen.
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.
And the moral of the story is :::::: don’t buy a diesel :::::::
I’ve owned 3 DPF equipped diesels. Combined mileage on them about 120,000 miles. Not one DPF fault or forced regen ever needed
@@hughmarcus1 And !
The catalytic converter get clogged too
Cars from 80s and 90s were much better. Far less electronics and no emissions crap. They could be fixed at home with just a few basic tools and didn't cost a fortune every time there was a problem.
@@felixalbion I totally agree I still have 90s diesel no problems at all
