How To Remove and Clean an EGR Valve

For anyone doing this, bottle brushes are brilliant to agitate the cleaner.

good video¡¡¡

Good video, thanks. Is there any way I could mess this up if I try this on my 2016 116d M Sport or is it pretty straight forward as your video? And does it need lubricating after cleaning or anything like that? Apologies if that sounds daft. My engine doesn’t seem to recognise I’ve pressed the throttle until a couple of seconds after and sometimes have judder issues at high speeds so hoping it’s this. Cheers

is this the same for the Mini N47 1.6 engine?

I think i need to do this, i have a 635d... sluggish acceleration, almost like an acceleration lag sometimes 🤔

Oven cleaner... is made... to break down carbon...!! Why haven’t I ever thought of that before?? 🤦‍♂️ Thanks, you’ve just got yourself a new subscriber! 👍

Would removing the valve affect the software at all? I’ve been told mine needs replacing and then it will need a software update, Would like to try to clean instead.

Actually did this today after seeing your video. Mr Muscle worked a treat! Dont know what differences I'll notice if any but it defiantly needed doing as it was pretty thick in there. 👍

will to car pass an mot with no egr ??

What u just done there does it make a noticeable benefit of the car

How often cleaning?

Legend, well done fella.

George what happens if you drive the car with the egr unplugged from the engine bay? I’ve got a N47. Thanks

Great video! Thank you!

Probably better off just replacing it.

George, I just bought M47 BMW e46 Coupe 2004 , from my friend , and my friend told me 2 years ago he had a problem with his EGR system. Actually his EGR cooler was destroyed, by the hot fumes coming from the EGR , I guess. He changed it for the Mahle EGR cooler, but since he did that in a BMW service in Italy, I doubt he told them to clean his EGR while they are operating on it. Many people told me if I clean EGR and intake manifold , I could get some "leaks" in the system after that, since "the car filled the holes he has there" and now when you clean the manifold, you will actually "open those little holes" .... Sounds to me like stupid logic, what do you suggest? Im not planning to delete the EGR, but do you suggest a good old cleaning of the manifold and EGR valve? I can see in some videos that you are cleaning the EGR only, even though we can see the end of the intake manifold looks gross while you are getting the EGR back in place. Will it help my car accelerate a bit better?

Be advised that oven cleaners damage aluminum, it even states on the package. I've seen lots of people clean EGRs, Turbos etc with it... Do it at your own risk. Better buy the specific product for EGRs, Turbos/vanes, MAF etc etc.

You can use petrol to clean very good shits from diesel. But the best thing is to take out this shit EGR valve,because only thing wich this valve doing is clog your engine with garbage 😏

Does the EGR apply to diesel engine only

Nice video man, cheers.

If i do this along with intake manifold and intake ports. Clear the codes. Im hoping its fine. What do i do about MAF sensor code?

If I've cleaned the egr same way as you did on same car on video and still no better doses this mean I need new egr valve

I did this and the carbon on my car was ridiculous it’s was maybe double even triple what’s in this video and it was also rock hard like literal hard Plastic and not soft at all. Anyone know why?

Car runs beautifully even before cleaning the EGR and it’s only done 130k miles. (Basically not even broken in the engine m47)

You can buy special spray for decarbonization :)

Hi can you walnut blast the EGR valve?

I’ve got X3 e83 3 litre D ... where’s mine on it ?

This build up in sut ... does it effect the power of the car ? did it with this bmw??

Hey George, any reason why you didnt clean the other end where the valve attaches to? Looks thick with carbon too? Why did you not clean that at the same time?

So if you remove and delete the egr do you have to have the car re mapped to tell the car it’s not their ?

Any issues with oil consumption on a series 3 2006 2.0 tdi. The step son bought one with 100k and its using a bit since the service. Done the vortex as per your video. Any tips?

Hi thank you awesome video and content... Can you please have the EGR DELETE video please

I think it maybe best to just clean the EGR valve after reading someones comment about a blanking off an EGR valve on a Freelander.

it's probably best to leave the EGR system as manufactured in a direct firing diesel engine. EGR reduces the temperature of combustion ( and hence the NOX pollutants ) by introducing inert (spent) gases into the combustion chamber in carefully measured amounts by the engines computer. When you remove it, you may notice some increase in power or economy due to the increased cylinder heat and hence pressure. This apparent short term increase in performance is why many mechanics recommend the procedure. But this increase in heat and pressure also causes premature failure of the direct firing fuel injectors since the tips of the injectors are directly in the combustion chamber. New injectors cost between $500 - $1000 EACH normally. It will also cause failure of the injector to cylinder head seals - usually a copper washer arrangement - and this results in mixing of coolant into fuel or fuel into engine oil ( or both ). This may entirely destroy your engine due to cross contamination, as well as causing the famous "run away diesel" phenomenon where the diesel revs out of control and blows up despite being turned off - due to it running on it's own fuel soaked engine oil. This is apart from the premature failure of exhaust valves and piston rings and turbochargers due to the abnormally high temperatures. A cynic might conclude that a mechanics real reason for recommending the disabling of the EGR system is the guarantee that he will make $1000's of dollars from the poor sap who does it when the engine goes pop.

Good video George! 👍😎🏴󠁧󠁢󠁥󠁮󠁧󠁿

Before doing this job get a new crankcase breather tube The old one will be brittle AF and snap when you take it off or put it back on. One of the two hex bolts holding the EGR will be rusted and impossible to remove so you'll need a removal tool or carbide drills. George shows utopia, in reality it's not like that at all.

Another good video, have you (or could you) do one for your Vauxhall corsa C?

Good video dude, need to do this myself!

What happens if you add the oven cleaner without removing the EGR valve?

Is the m47 engine reliable,?

They are all different in different texts so this barely applies to anyone

Really appriciated it 👌

Hello I did a egr cleaning it was so much dirty, but I didnt feel any difference?

Any advice on how to remove the egr value on a n43? 1 series 120i model 🤞🤞

it's very easy on this vehicle.

I bet the intake needs cleaning as well bro, I just did both on mine, both were full of carbon. As well as in the cylinder head whilst you at it.

HI THANK YOU FOR YOUR VIDÉO NICE JOB, I ‘M LOOKING FOR A X5 F15 TUTORIAL HOW TO REMOVE EGR AND CLEANT IT DOES ANYONE HAS ? THANK YOU

God i did this 100s of times @ BMW

I used the back of a junior hacksaw blade to wire off the carbon and then mr muscle , finished off with some cheap coca cola and rinsed with water. Came up better than new

Nice video! I have the M57 at it seems to be less room to actually get the EGR valve off after loosing the bolts. Any tips greatly appreciated. Cheers
