BMW 530d F11 Diesel Fumes in Cabin - EASY FIX!
Вставка
- Опубліковано 2 жов 2024
- At low speeds I have noticed a diesel/exhaust type smell in the cabin. It comes through the ventilation system, so this is how I fixed it - very easily & cheaply.
This is a common issue on many common rail Diesel engines & is all about the fuel injector ‘leak off’ or fuel return line connectors. All easily accessed at the top of your engine 👍
A very, very helpful video. For the record, if you just leave it, after a while the diesel turns into a black baked-on mess that is far harder to remove. You tuber Legitstreetcars (?) refers to it in a past video as Black Death. On reassembly it looked as if removing the leak off connector is a two step process, lift up to unlock and then remove. Of course the same symptoms could arise from leaks at the lower copper sealing washer but you had just changed those, as you said.
Naaah I think the black death is actually the gunk that accumulates around a broken/improperly seated injector and then spreads around - ruining and killing everything. Either way - leaking injectors are NOT GOOD - no matter which end they leak from.
Thank you for video. I have BMW 520d F11. Where did you buy this product do you have LINK?
I have the same car and same question. Where do you get them or what are the dimensions of the o-rings? Thanks
Nice job well done 👍🏻 Nothing worse that stinking diesel fumes in ya motor 🙈 Looking forward to seeing the next fix 😆
Good advice, as usual. Please, get a detached microphone... Thank you.
Any idea what the BMW part number is? I’m having trouble finding it at my local supplier and don’t want to have to go to the dealership $$$$
Perfect little video for a Sunday morning 👍🏻

Hi - I have an issue of spent fumes entering the cabin when I come to a standstill. There's an error code - Auxiliary Coolant Pump short circuit to ground - I have read that if this fails, it can let fumes into the cabin, so logically this might need replacing. Do you agree? Any idea where it is??? I have an F10 530D pre-LCI (2010). Many thanks.
I’m not too sure I’d jump to the conclusion of those two being connected. Definitely investigate & sort out the short on the aux pump, but the two areas I found created fumes were:
1) the injector leak-off tubes weeping diesel
2) the EGR bypass cracking on the underside, next to the EGR cooler - very difficult to see unless it’s removed for inspection, or perhaps with a borescope
Very useful video. Can you please let us know where you got the o rings? This would be very useful. Thank you

Excellent Video! Can you do a video demonstrating how to change the injectors? Cannot find it anywhere on the internet. Much appreciated :)
It’s actually very easy on the N57 engine. Unplug the electrical connector, undo the HP tube connector, loosen the C shaped clamp holding the injector down & then undo the bolt holding the injector down. A bit of a twist (use a spanner on the metal injector body if necessary) and it should come out.
@@Nut_Job. Thank you :) Turned out it was my turbo that's gone, too complex for me haha
Helpful and well filmed - will check immediately on my 2012 N57 - but the channel "content" seems to have subsided. My guess would be a new wife (understandable with a BMW) who's not too keen on letting the guy enjoy cars along with some publicity. Oh well.
Haha, great comment 😂
Did the smell burn your eyes? Mine is very strong.
The leak off system is to help bleed the injectors and lubricate the tight tolerances in the injectors moving parts internally.
Nice vid. But wouldn't it be better to replace the entire hose/pipe? My thinking is if 1 of these seals is kaput, then the others probably aint too far off either.
In the end, that’s what I ended up doing. I was just trying to avoid spending £50 for the sake of some o-rings… but it was easier to just replace the full fuel return tubing 👍
Handy. Might change mine seen as the cost is miniscule and doesn't take much time.
I have a 2013 x5 35D .... Could this be the cause of the exhaust smell coming into cabin only when outside temperature is cold??
It could be, and you’ll be able to check quite easily if there’s any diesel pooling by your injectors. I also actually found that my EGR was leaking exhaust gases (see my other video on the EGR) which was the main source of cabin fumes 👍
With milage have your car?
Good morning and Thank you for the video, an easy fix!!.
Did this cure your problem or did it return? many thanks.
The O rings I bought we’re perfect so I bought a new fuel return line from Autodoc. It cost about £45 from memory, so felt it was worth it.
@@Nut_Job. Thanks
👌👌👌🇮🇳
Is this the same procedure for the f10 520d because I get burning smell from the ventilation when I turn it on ?
It could be many things tbh. It will need investigation to see where the smell is coming from & don’t ignore it because you don’t want something burning getting worse
@@Nut_Job. do u think it could be the injectors leaking same as your car?
Not another fault😲😲😲😲
Thanks a lot. Will take a look at mine. Keep em coming!
Lovely Jubbly Mr NutJob.
Super got a m57 engine
My injectors has same fluid around them can this cause oil consumption? Why is this happening ? What consequences it has?
No, not oil consumption but you will have diesel fumes smell & it will probably affect your fuel economy a bit too. It’s also not good having fuel splashing around on top of the engine either.
Nut Job Leaking fuel injectors can cause Oil Thinning
At engine shutdown the fuel pressure should maintain operating pressure or just below that for a substantial period of time. Fuel injector pintle, ball or disc seat leaks as well as the bottom O-ring leak on a side feed injector will cause fuel to escape into the intake manifold. From the manifold the fuel will run down to the intake valves. If an intake valve is in the open position that fuel will enter the cylinder where it will leak past the rings and eventually mix with the engine oil.
Oil thinning can lead to engine bearing damage and scorched cylinder side walls. In some cases it can even lead to an explosion inside the engine. It has been reported that leaking fuel injectors caused hydro lock because so much fuel has accumulated on top of the piston that when the engine was turned over the engine locked because it could not compress the liquid in the cylinder. Hydralock can cause bent connecting rods, broken pistons and blown head gaskets to mention a view. All very expensive repairs
I Have Strange Knocking noise Some times When engine is Warm Knocking noise My friend has same car and he never has that noise 🤔 Do you ever noticed knocking tapping noise Its there is the normal Diesel trrrrr sound and then i have this outstanding knocking taping noise ...
All of that is correct, but this video is not about injector leaks... it’s the fuel return line which is leaking. This is very low pressure & only leaks onto the top of the valve cover.
Nut Job Aham got you , Then no idea why it eats oil and has strange noise, my car has an additional cooler on top, When they removed it last time Because changed Glow Plugs , i had Air stuck in system for 1 year , they did the Ignition on temp high fan low etc , but it didnt worked , then i told them change the coolant They did it as described by bmw With the equipment which Push coolant in and Suck air out , still didnt solved it and after one year me Taking off cap , constantly the air gone . When engine was warm and i putted temp from low to high i heard water gurgling noise and my water pipe never went lose it was hard all yime even after 1 week without using it . I think the heater core had air in it... So Im afraid to remove that cooler

This was injector test but engine was cold , sound is only when warm what you think?
Very handy vid
These cars could easily be built to last much longer
I’m certain of that. It just doesn’t suit the manufacturer though does it? 😒
@@Nut_Job. nope but great vid im having fumes coming into the cab of my 318 n47 i think its the gasket between the turbo and the dpf wish me luck
@@freeman1352 did you fix that?
@@poe3958 yes it was the gasket these cars are piles of scrap nothing but trouble
@@freeman1352 the gasket between the dpf and the turbo?
Always relevant concise content..however, please address the woeful audio levels..
The audio sounds fine on my phone?
@@Nut_Job. Please get a good external microphone. And check audio levels on different parts of the video (you nearly made me deaf when you put the engine on). Great content though...
Great fix mate
Wish my 550d engine would be same space ...
It's the same 3.0 R6 engine mate, only with more turbochargers
gangstarapakira :) there is much less space I have an extra cooler on the top off the engine, My Inlet pipe also different my Intake is also different its metal, Its not same at all, pistons,Injectors the engine it self not same at all,, check part numbers alone, if your engine fails can you buy a naked engine block from 535d or 530d and used in 550d? Dont think so. But i guess u also have a 550d thats how you are so Informed ,, I fix my car and its totally diffent brur
@@bmwsincekid Main engine block is ~98% the same. There are some differences but mainly in covers, pipes etc. It can't be the same because of €. BMW makes almost the same parts in so many versions, so customers have to buy new parts. If u want to see tight engine compartment then check m57 in e46. It's hard to put ur hand between engine and wheel arch
My E90 has that smell at low speed, think I'll have a go at it's return seals, but I won't be using anything sharp to remove the old rings, the T-pieces are made of plastic (if they're the same as the ones used on the M47 engine and could get damaged, as could fingers! The safest way is to pinch the o-ring on one side and push, it should then loop up just enough to get hold of, hard to describe it in txt but it works
Excellent video.👍🏽 Where can I purchase the seals from as BMW sell the line complete? £74!
Mine O rings sit on the stem and have a different pop up connector 2010. Bought them from Hayley Group 50p.
You make me want to drink coffee
Surprised when the car went back to bmw for the recall they didn’t spot/point it out or address the issue. Looks to be a common problem
I think you’re putting too much faith in BMW... I seriously doubt they look at hardly anything beyond the actual recall notice (despite what the report states when you collect the car)
Nut Job yep haha what was I thinking? I’d be interested to get your take on the car /brand since you’ve had your fair share of problems - in comparison to say the rangie or any other car you’ve owned
You've just gained an extra 1 MPG 👍
😂👍
Fantastic videos, but this car seems to be endless trouble!
I know... 😂
Good for channel content, but bad for a daily driver....
Normal for high miler Bimmer. I used to have periods of boredom and surplus cash. A 120K mile 550i cured both those problems
