EGR TROUBLE

Join me, DiagnoseDan, as I tackle the challenge of diagnosing a BMW diesel that's throwing some puzzling EGR fault codes. In this episode, I walk you through every step, from verifying the initial complaint to the nitty-gritty of pinpointing the issue. While that check engine light might play hide and seek, the stored fault codes have a tale to tell. With a mix of technical know-how and a dash of humor, I'll show you the hurdles of dealing with an elusive EGR valve problem and the crucial role of a meticulous visual inspection. But here's the catch: what's really causing these fault codes? And how can you ensure the EGR valve is installed without a hitch? I've got the insights, but the final solution? Well, that's a secret you'll have to watch the video to uncover. Let's roll up our sleeves and diagnose it together!

The cars are so well made nowadays,that it's amazing, they inteligently manage to carefully design and make a simple 2 bolt EGR valve that you absolutely need a 1000 euro computer to allow you to tighten those 2 bolts, just amazing

[@JamOwnzU]

I am a technician and so when you asked the question "Should the EGR valve be open or closed during DPF regeneration?" and I didn't immediately know I thought huh? How come I've never had to consider that before? Good question. But what I do know about EGRs is they allow spent gases to occupy some of the combustion chamber therefor reducing exhaust temperatures and NOx emissions as a result. What I know about DPF regeneration is the temperatures are extremely high to break down the hydrocarbons clogging the filter. Logically then: The EGR should be closed during a DPF regen. But I imagine there are specific circumstances in the mapping that will allow for it to be open maybe some of the time. Good video again Dan. You're a legend and obviously really know your stuff.

The best and most interesting technician on youtube , need more big dan , 1 video a day should keep everyone happy.. thankyou sir..

[@Diagnosedan]

Thanks for the great comment!

[@ambitioushunter]

EGR valve should be closed during dpf regeneration, then all heat will come thru dpf to help gain particulars burning temperature. Another great video Dan!

[@ALLin-one1]

Yes am with u with the answer

[@Diagnosedan]

Thanks for the comment 😉

[@wilco3365]

When the egr valve is open, the temperature of the exhaust gas will decrease. With a closed valve it Increases wich is necessary for the regeneration (around 600°c i believe)

[@Diagnosedan]

Thanks for watching!

Something new you learn every day. I wonder how many people have been fitting them wrong all this time. 👍👍👍👍👍

[@Diagnosedan]

I was thinking the same🤣

[@royjennison3916]

Dan , you are 100 percent right in your diagnosis , and fitting of this part , i am a BMW tech of 30 years , as you know BMW are on a masive EGR cooler recall , the last few EGR recalls have being change the Valves and program the car , then was change just the EGR coolers , now it change EGR coolers with valves as well , i suspect the cat will be due for that recall .

[@Diagnosedan]

Thanks for the comment 👍

[@intelligentauto737]

The EGR and the Throttle Body are active during regeneration, (I’m not going to say open or closed as their positions change) the reason for this is to control the level of oxygen entering the combustion chamber which then controls exhaust Temperature during regeneration.

[@payaso2297]

[@FoookOff]

EGR stays closed on my 3.0 TDI.

[@Infiniti25]

@@FoookOff intentionally?

[@shueibdahir]

Stays closed on my 2.0 TDI PD BMP. Infact my EGR is programmed off so it stays closed and is blocked off. It still regens and reaches temperatures of 800c. The only time my regen can't initiate is when there is an EGR code stored on the computer.

[@SA-he5ej]

I like how you explain everything. Unlike other channels like this where i get bored, this is quite enterntaining and informative.

[@aminmombini6882]

hi Dan, in answer to your question, to regen the DPF , it need to be heated about 600 degrees, and it would be done by injecting fuel ATDC ,it's like to make stroke in the DPF,so the EGR should be closed , to not cooling down Exhust temperature.

[@tecnaman9097]

You've been watching the Hydraulic Press Channel Dan. And the EGR valve should be closed during regen. Thank you for another entertaining and informative vid!

[@jonathanhelmbold1162]

During the DPF regeneration cycle, some diesel gets sprayed by the injectors on the exhaust stroke, to help burn off the soot caught in the DPF. EGR valve would need to be closed. Always love your videos man! Greetings from South Africa!

[@RealButcher]

Thanks man, Interesting those EGR valves. When I bought my iQ in 2010 the EGR was draining from before the catalyst, from the exhaust. These were the then " older" model iQ's (till second half 2010) . After some strong discussion with Toyota Holland they replaced the EGR valve, that now was draining after the catalyst. All the newer models from second half 2010 had it in this way. The older models had some problems due to the placement of the EGR valve. I think owners in England went to court about this. Cars would randomly stop having power and go in limp-mode. After a lot of discussion here in Holland with Toyota, they exchanged the valve and catalyst. For free. It has never been a recall action. Weirdly.

[@danielsoderstedt1941]

There are regular car technicians, and the there is Dan. 👍👍👍

[@Arlo10]

I can watch your videos for hours, and learn a lot from you, thank you Dan 💐

[@HobbySMD]

Dpf regen happens by injecting more fuel post (after tdc). This will make exhaust heat. Egr is allways closed under regen to get maximum o2 in to combustion. A leaking egr valve will make combustion colder and less clean, making life for dpf hard..

[@GarthGoldberg]

Dan, I've been sitting around waiting for you to ask for help.

[@Diagnosedan]

[@gerigesquiere66]

With an EGR on I got DPF regenerations each 250km. With EGR Off i have a regeneration each 900km. In a normale case when regeneration is active the EGR is close. An open EGR make a lower inside burning temperature. For a good DPF regeneration the DPF needs a high temperature. Thanks for the video, Dan. To check regenarations I have connected a warning licht to the rear window heating connection. So I have allways a completed regeneration. If lamp is on i drive till the lamp is off. Takes +/- 10 minutes.

[@notrut]

My petrol Skoda Octavia EGR valve was sticking/jamming last year and my local garage took the top off to reveal the same problem ... Soot & Carbon. After a vacuum, scrape-out and lubrication everything was fine .... but only for 3 month. Than I broke down at a particularly bad junction, and had to be recovered with my Dog in the car .... EGR was the fault code. A new EGR valve installation was £303 in rip-off UK ...

[@unclemarksdiyauto]

Interesting that KZbin just notified me 4 weeks after you uploaded this video! Not sure what’s up with that! Yep all notifications selected! Thanks for the video Dan.

[@leiflillandt1488]

After looking at this video a second time, I start to understand what's happening. One thing which isn't mentioned is that when the valve is stucked, the engine die after some seconds, and in the meantime it run very rough. When you try to start several times, may be the engine keep on running. In my car, X3/F25 30d 2011, it got stuck this week (fault code P042E). Long story short. There is a plastic cover above the gears compartment, by removing that I could see that the axle/valve was stuck in open position. This time I could move it up and down by the hand. I put som grease on the moving parts, and I will drive a little to see what happens next then I put the cover back. There was no soot at all among the gears! The car has been driven 246,399 km, but it is "new" for me. The adventure goes on... 🥺😉

[@Jake-sq7ve]

I'm so glad I found your KZbin account a few years ago, everything you do seems so easy and professional. I work as an educator in car mechanics and sometimes I make my students watch some of your videos and answer questions, keep doing what you do! Best regards, Jake!

[@jacabaca7440]

During the DPF regeneration process diesel fuel is injected into the cylinder after combustion has taken place on the exhaust stroke (post injection) so it is pushed through the open exhaust valve into the exhaust system. Here it is burned with air to generate the heat required to burn the carbon (soot) in the DPF, so the EGR would be closed to increase the temperature. Keep it up Dan, great videos! Even a school boy would understand what you're talking about...:)

[@Diagnosedan]

Thanks for the comment 👍

[@rbspider]

The EGR on my 84 Lincoln Mark VII would get stuck open and I would have chunks of carbon holding the valve open . When stuck open the car would not idle. Never figured out what caused the carbon. I think it was related to slack in the timing chain , causing the vehicle to run rich. The work around was a screen that caught the carbon .

[@elvisvwvw]

love it when istructions says refer to service manual by the car manufacturer!

[@TheDisgruntledMechanic]

Thanks Dan! Always learn something new when watching your videos!!

[@Diagnosedan]

Thanks for taking the time to leave a comment Mike!

[@Capitanvolume]

I've had this problem on the street sweepers in our fleet. Lots of low load operation means that soot builds rapidly. However the egr valve is over 500 dollars and the labour to clean is only $180. So we are clean them out.

[@Diagnosedan]

Makes sense if the egr valve is that expensive

[@armyvet92]

Another AWESOME video Dan ! Thanks for all the lessons you provide us all !! Much appreciated !

[@Diagnosedan]

Thanks!

[@Hotaru_T0m0e]

Excellent! Do you think this is the reason that a special key is required? To ensure that the engineer is alerted that there is something special in the assembly procedure? I see no other reason for the manufacturer not to use regular bolts.

[@markw4710]

Excellent point. I was cussing the manufacturer when I initially saw those security bolts thinking to myself, 'why, just why?' Your observation probably explains the very reason.

[@Diagnosedan]

Yes that's the reason!

[@Garth2011]

The axel or pushrod on that EGR valve has a manufacturing flaw where it meets with that "fork" arm that the gear operates. The soot was collecting in that area causing it to bind within the fork. Amazing that the pushrod seal allowed all of that soot inside the mechanical area but if that was its design then the fork and pushrod meeting point is a dumb design. If that seal is supposed to keep out the soot from the interior parts then, the seal simply failed and likely due to heat and not so tested seal materials. Maybe the owner needs a few trips on the expressway !

[@Diagnosedan]

Thanks for the comment

[@alrifainidal]

Great video Dan. The EGR valve should be closed during DPF regeneration

[@Diagnosedan]

Thanks for watching

[@doctorrobert60]

That pressure test on the old EGR valve did a great job of cleaning out the "junk"😜

[@wildmandon1]

Maybe, if you didn't have a scan tool that offered that feature, maybe you could retract the plunger with the tool you used to test it with? Even if you retracted all the way, it would seem you would have adequate clearance for mounting.

[@kitookepeter6889]

Hi am peter , long time, the EGR is actually active during DPF regeneration because once the RPMS increase the exhaust gases have to be recycled ,so with its duty cycle it opens and closes as the dpf is regenerated. thnx allot

[@Diagnosedan]

Thanks for watching

[@guitarplayinman100]

I had this on my 2011 520D , new EGR sorted it, FYI there is a couple of EGR cooler recalls of the BMW B47 engine [ my Current one] , cooling fluid leaking from the EGR cooler onto a hot exhaust manifold can cause a fire.

[@Diagnosedan]

You are right👍

[@mikechiodetti4482]

Great video, the install tip and the question. I would think the valve needed to be closed during regeneration so maximum heat can burn the particulates in the filter.

[@luisann7958]

Hello Paul

[@Mobilemechanicuk]

Hi Dan a potential cause for the parasitic draw could actually be the egr too As its commanded shut after engine is off then it will often try to satisfy the position sensor by trying to release the egr, this is the reason you sometimes hear a loud buzzing from the failed egrs with electronic actuators. Its not something I've proved like but I know the egrs are required shut during start up to allow the maf and intake calculations to be accurate without unmetered egr flow. The current draw could be similar to when a starter goes duff. You still send the same power that's required.... but it does nothing and if the computer is trying to close a stuck open valve by commanding the motor to give the spring a little push for a while after cars of it could create a draw. Just a thought. Hope your well. Haha get top Don to send me freebies and ill love them long time hahaha

[@Diagnosedan]

Thanks for the feedback

[@comment943]

I love these videos and your diagnosis are alaways great but you surprised me that you made a mistake in that you never checked to see if the egr cooler was blocked or leaking coolant as this is a very common problem on these bmw/mini engines there is even a quilty enhancement for that issue at the moment

[@Diagnosedan]

If the egr cooler is blocked i wouldn't have the faultcode egr flow to high. The car is not loosing any coolant and everything was dry inside

[@comment943]

@@Diagnosedanhi Dan love your videos but didn't say it was blocked I said you should have checked it while you had the valve out and yes they can start blocking up and sooting up the egr valve that was your fault sticking egr return spring valve ya ? When the soot builds up after a period of time they over heat the egr cooler then crack and leak coolant I see it every day unfortunately anyway keep the videos rolling 👍

[@polnashautosgarage0001]

That's a cool one Dan,Best option was to replace,otherwise,eventually,the carbon soot would have found its way back to the drivers

[@petargalic4765]

Well done Dan. It's understandable why you decided to change that egr valve for brand new, you own the shop and by trying to clean that valve and possible problems down the road equals doing same job twice hence losing time and money, probably having unsatisfied customer. On the other side that valve looks pretty simple, if that was my car I would try to soak that valve in some kind of solution that dissolve carbon deposits, little bit of compressed air and some kind of fine brush.. To answer your question - should valve be open or not during dpf regeneration - I think it should be closed because regeneration needs higher exhaust gasses temp and recirculation is doing opposite thing by bringing O2 down in combustion cycle, narrowing conditions for harmful NOX gasses to be produced.

[@Diagnosedan]

Like i say in the video, if its your own car you are working on you can try to clean it 100%.

[@kain0m]

@@Diagnosedan The problem is that the black soot doesn't cause issues (soot is actually a lubricant). It's other, harder deposits such as oil ash that form a hard high-friction layer which lead to sticking valves. And that layer is virtually impossible to clean off. We've had many issues with sticking VTG systems due to such deposits forming between the center section and the variable guide vanes. Especially after regeneration, when there was no soot inside the VTG, they tended to start sticking. In the end the supplier of the VGT had to modify the tolerances and the material spec of the vane actuator shaft to fix this issue.

Great vid again, and the shop looks cooler than ever👍 That's quite interesting, didn't know the EGR valve had a service mode on BMW? Have an old Mercedes (220cdi/W211) i like to screw around with. And i can tell you that the EGR valve takes two minutes to remove with a T30 and E10 bit. No cooling lines to clamp off. And it is a "caged" type so the valve isn't just hanging out in the open like that. And to answer your question, EGR is closed during DPF regen. as many of the comments is claiming. But not completely, i'm guessing the EGR position sensor is around ~2,5%.

Common issue on European Fords when the egr valve /motor is changed is mechanics doesn't calibraye it and it slams the valve over and over until the steel shaft fatigues and shears completely off.

Always good to see your videos, I hope ya get time to post up more often😃
