Hi
First of all (and I have also mentioned it in the video), I want to apologise for misleading you at the start of the video, by saying we will be fixing the 40 Mph speed limit, which looked like a limp mode condition...
Throughout the diagnose, I decide to tackle the fault with the throttle body, which although would not be causing the limp mode condition, it definitely contributed for it...
So, I made this video for the throttle body problem only...
The limp mode, I believe is being caused by the DPF, and that is something that deserves his own video...
Now, the issue with this throttle body, is a common thing, on all BMW 730d, 530d, 525d... basically all the ones with the base M57 engine...
Follow me on this video to find out the problem and how to possible fix it... yes possible, depending on how damaged it is, it might not be possible...

Thanks for the detailed fix action. I had the same issue on my 2009 530d and your solution worked perfectly for me. I used a dremel tool to make the cuts on the casing and it worked well. I cleaned out all the oil, saw the break in the PCB and soldered a thin wire across the two solder pads. I did have one issue when I was testing it with the cover off - the black gear went spinning off and it took about 10 minutes for me to find it (lodged in the fan casing). But then Voila - no error anymore. Hopefully my DPF will regenerate tomorrow when I take it for a drive...
🤣🤣🤣
Glad you found the flying parts...
Thank you for watching and for your comment!
Great video, man! Exactly the same issue with my throttle actuator. Fuse blown and circuit board was really burnt at the spot. Soldered up with a thin copper wire. Now it works great again. You saved me a lot of $$$ 😉
That's great!
Thank you for watching and for your comment!
I reparied the oily throttle valve . I have opened the case with an screw driver. The case of the electronic I didnt seal it. Now i have the Problem 3F77. Is it important to seal the case of the electronik of the throttle valve?
You saved me. I manage to take the case apart without cutting the corners. Just made my way with a sharp straight screwdriver, slowly bending the edge, then it poped out.
It was full of oil and it was coroded in the exact location like yours, I fixed it with a small wire, then i seal it with a glue gun... so it wont corode again that spot, then i lubricate the seal, and pop the case in. I hit it with a small hammer on the edge to make the cover thight again so it wont leak oil. Everything works fine for now... we will see in the long run. Thanks buddy!
😊
That's great!

Hallo warum muss nach der Reparatur der Platine der Drosselklappe die Abdeckung abgedichtet werden? Ich habe nach der Reparatur nun den Fehler 3F77. Motor geht nun ständig in den Notlauf. Die Abdeckung habe ich mit einem Schraubendreher gebogen und auch nicht abgedichtet.?
Great work as always. Your knowledge is great and thank you for taking the time to share that knowledge with us. It's a pleasure. Also the dpf problem can also be caused by the faulty glow plugs and glow plug module I had the same problem on my 525d. They have a similar engine so that might be something worth looking at.
Hassan Raza
Hi
Thank you for your comment...
The glow plugs on there own are not critical for the DPF to regenerate... but they indeed play an important role...
It might be though, that on some cars, or even on some BMWS, depending on the engine ecu software, they are actually imperative, and need to be fully working...
I will be soon posting another video on this car, regarding the DPF... stay tuned...
Thank you for watching!
Tahanks for this video, it resolved my problem in e87 118d. Car lost power when driving in every gear but not every time, it was horrible to drive... I've the same electronic fault like in yours video but error in computer was: 43E2, 43D1, P2620, P2621. After repair car drive normal and have no errors:)

Hi
Thank you for watching and for your comment!
Cheers for great repair video at component level brilliant, the blocked dpf ihave found is related to faulty glow plug/plugs that don't allow it to run a regen because it can't generate enough heat in cylinder and thus raise exhaust temp cheers sandy
Hi
There is more that just that...
I will be soon publishing the video for that one...

Just did mine , same throttle actuator used on many BMW . Mine a 635D same issue blown fuse , when opened found lots of oil . Soldered jumper wire , cleaned pcb with contact cleaner left to dry and is now working again. 3mm hole drilled in bottom to allow further oil to escape!

Really appreciated!
Great video!!! I have the same problem and I would rather try to fix it before investing in a new one. Will tackle over the weekend.
One bit missed as of could show the exact location for drilling, but thank you anyway.
Drill and the lower point when the throttle body is in place... so any oil can drain...

Hello, in the BMW E65 730d facelift, after DPF burnout, there is a jerk every time when extinguishing. When the car is turned off in other cases, this symptom does not occur. While driving, there is a wave of revolutions as if something is choking this car, and what is responsible for the frequent initialization of DPF burnout
Absolutely unreal ! Enjoyed video now I know how to solve problem
😊
Hope you get yours sorted!
Thank you for watching!
Great job, Mine is E60 530xd LCI with removed DPF(Hardware + software) and this error came to me too. The symptom of the car is that in low RPM when the gas pedal is pressed the engine sound like is dying, like the air is not enough and the car does not accelerate as expected. I'll try to fix it and will share the result.

Hi Bro, nice video. Could you Tell me which Fuse i need to use.

Excellent video buddy, I will check the solder tomorrow.. My issue is the car wont start and is throwing up the same code for the throttle body. mine a 2006 x3 2.0d but looks the same part. mine too was full of oil, I didn't think ti check it with the cover off 👍👍

This should not prevent the car from starting... unless is stuck closed...

Hi mate great video! I have a e90 330d M57 motor with the same 43E2 fault and engine shakes when shutting down. I opened the TB and found the exact same spot to be blown like in your video. Since I am no soldering expert I can get a micro pen type to do it but what is this wire you used to make the new bridge? Where can I get something like that? Thanks a lot !
Hi
Just use fuse wire...
Thank you for watching and for your comment!
@@LMAutoRepairs I feel stupid now... Thanks a lot for the lightning-fast reply! I will try it out and report my findings. Btw what is the best spot for the new "drain hole" you drilled? Is it the corner directly under the pcb and the shaft?

Yes... pointing down when the TB is installed... make sure you clean all the oil from it...

Hey, my digital microscope arrived and I have figured that my fuse is blown in the exact same spot! Amazing! I'm now wondering, I've never soldered before, do you have any guidance or videos on how to do this? Do I need to remove the PCB board from the enclosure? Any advice would be amazing and thanks for this video!
Hi
No, you don't need to remove the board...
I some videos on soldering... but nothing too detailed...🙄
Thank you for watching and for your comment!
Hello mate, great job, great channel!
Could you help me please?
Got same error on my e60 m57, fix it by soldering that blown contact, but.... Got now 4687 Throttle valve actuator : electric or mechanical defect (position sensor error, control deviation, motor overcurrent) ; Test condition met ; Error currently available, but not saved yet (Entprellphase) ; Error did not cause a warning lamp to light up; Error in "Entprellphase". I'm using INPA. Please ca you advise me what to do, what's your opinion? When you install back the gear wheel, throttle position must be close, or doesn't matter Thanks in advance
Hi
The cog system is spring loaded, if I recall correctly... so just put everything back in the rest position...
Try to do a learn to the throttle body...
If you have other issues with the component, like a bad motor, or something else on the pcb, then this fix might not work...
Thank you for watching and for your comment!
This Video is Long time ago thanks it works on my e87 bmw👍👍but stil give 483D Function Throttle Body but i dont check if it rigt position with you hand Maybe You Can Help Me👍👍👍you stil Life Right😂
Hello, this was a great video first of all. i had the same code (43E2) on my 320d e90. did everyting what i saw in this video, and the fault is now gone. but now i have another fault which seems to be related with the throttle body aswell (the fault code is 4687). btw the 4687 code only appeared after i fixed the 43E2 code. any ideas? i want to try finxing it myself, but im afraid ill have to buy a new part
Hi
It still a code related to the throttle body actuator...
First, does the code comes back when cleared?
Second, after the repair, is the throttle body working the way it should?
Thank you for watching!
@@LMAutoRepairs yes, the code returns almost instantly after me clearing it, but i actually did not test it in the way that you showed me in this video, ill have to check. I think the actuator is too far gone for me to fix it, well atleast i tried :) thank you for your reply!
@@erlandaspilypas727
No worries...
👍
Another great diagnosis. Enjoyed watching that. 👍
Thank you, for watching and for your comment!
Hello, nice job. My car is throwing the same codes. I'll check the Throttle body but can you give any leads to the 41BA code for the backpressure sensor? Is it the sensor itself? I can read the pressure in the DPF on live date and it's about 15mbar on idle, so I'm assuming the sensor is working
Possibly...
But is it working under pressure?
Are the pressure within acceptable values?
You need to check all those things...
15 mb at idling is already slightly on the high side...
👍👍👍
@@LMAutoRepairs Well I'm driving the car mostly in the city, so it doesn't get the chance to do a regeneration as often as it should and sometimes the pressure goes up to 60mb! I'm thinking that there is something adding to the dpf getting clogged up, like injectors, burning oil, egr etc. Injectors seem rather fine on live data, and the EGR seems to operate normally but anyway, I'll try and work on that throttle body and see if it get's rid of the pressure sensor code as well
👍
Hi
I fixed it with my microscope goggles and it was actually the same spot. Will take it for a run now. Next time do t cut the edges no need. Just use a wrench for water connection and pull it of pass by pass. Hope it helps. Tell U after the test run
👍
Thanks!
Well it worked so far. I don't have any surgin between 1500 and 2000 rpm but still don't have the power as before. I have like a spot on the gas, like a kick down, that it do shift down but the gas doesn't arrive. It's a e61 if you have any ideas. But thank you so much for all your help.
@@DesignByAntonioForteza
Well... scan the car and look at the live data...
Otherwise is pure guesswork...
I Would and I did but it only gives me the throttle but now it is ok and must go back to my think tank
could you tell me what my gearbox error means on my 730d e65. 51AC - No message (throttle valve/accelerator pedal) from engine managment; - intermittent
By sheer fluke I stumbled across this video whilst trying to discover the issues with my throttle body and will attempt the fix tomorrow.
I was though wondering without correct fusing is there any risk to the ecu as I assume the plug goes directly to it.
And as oil doesn't conduct electricity what was the likely cause of the original one giving up?
If using fuse wire would anyone like to hazard a guess at what rating the original trace fuse was 🤔
It is working. Great job! Thank you so much!

Hi there! Is M47 throttle body interchangeable with N47?
I've repaired it the same as you, however I still get an error code for the throttle body and the actual motor get very hot. Do you have any suggestion?
You might have other issues...
Make sure the body valve is moving OK... and not getting stuck...
Other than that, could mean yours is beyond repair...
👍👍👍
@@LMAutoRepairs Looks like it, I've repaired it the same as on your video and it's working and moving as it should. It still throws up an actuator fault, not the same one as before, but just another one. Looks like it's a replacement for me
@@LMAutoRepairs I repaired my old one and then got a used unit and same happened and repaired the used unit and still the same, looks like I'll be getting a new one. Either way, thanks for the great video 😊
Another bad design by BMW, thanks brilliant piece of work done, it might explain my fault codes 00483D throttle valve actuator fault and possibly linked to crankshaft sensor signal fault 008E91. Mines misfires at starting whether cold or warm and there's a slight hesitation when switching off. Will definitely investigate inside the casing of the actuator. How did you clean the oil gunk out from the casing, any special solvents?
Alcohol...

Would acetone be ok

Hey mate I took my throttle body off my x5 e70 diesel and it was full of oil I cleaned it using contact cleaner and noticed I had the same fuse piece broken like in your video so I shorted the two points and the motor responded but now the car will not start...I think I blew a fuse please tell me where the fuse is for the circuit that plugs into the throttle body please
Hi
Have a look here...
fuse-box.info/bmw/bmw-x5-e70-2007-2013-fuses-and-relay
Great video! But what if the oil creeps up the board and short it again (even with the small hole), then the fuse probably wont blow and the short will go into the DDE and short it instead..? Sounds scary 🤔🤔
Use the correct rate fuse wire...
Thank you for watching!
👍👍👍
@@LMAutoRepairs Would it be possible to solder in a "external" fuse, so you solder wires to the points and then solder a normal pcb fuse to the wires?
Do you know what amp fuse it needs? My throttle body isnt working either, and it has a good amount of oil on the outside (oil + dirt), so i guess it has the same problem.
I have soldering equipment but not for tiny stuff.. So im not sure i will be able to solder anything really.. It looks really small.
@@LMAutoRepairs I fixed my throttle body yesterday but used a normal wire. Would be great to know what amp it needs. Planning on using the fuse wire from a glass fuse. Do you know what amp would be enough? Thanks!
Started the regenerating for dpf after a few km's. So ut works great now, saved me some money!
is the "fuse" you soldered, between the ground and the power pin,? i have 6Mohm between the 12v and ground pin..
Thanks bro. It's saves me 200euro.

LM Auto Repairs at least throttle position?
Hello,
I have similar problem on my BMW E65.
Present codes: 4677 Throttle-valve actuator, 4877 Throttle-valve actuator, 0043D1 Throttle-valve actuator, activation, 0049E7 Throttle actuator all are DDE codes.
I have managed to remove EGR and Throttle Body. Cleaned everything and put together. A reason why I was removing to inspect why Throttle Valve doesn’t move when engine is being switch off and just shake the whole engine. I can move Throttle engine valve by hand.
Have done a test with ISTA+ against Throttle Body and valve doesn't move at all.
What could be a reason why doesn’t function?
How can I test is wiring or fuses are ok? I didn't dear to remove that cap from throttle body without testing out all possible solutions.

Hi. What is this throttle body for in diesel engine?
Slawek h
Hi
I will be soon posting another (and last...), video on this car, regarding the DPF, in there I will be explaining it...
But basically, this have two main functions on this engines at least...
One, it closes when the engine is turned off, starving the engine of air, allowing a smooth shutting down... another one, is when egr air is going into the engine, this closes slightly, reducing the amount of fresh air, that also increases the combustion temperature, which helps on the regenerations of the DPF...
Hope that answers your question.
