Love ur work grant!! Such an inspiration for the n55 life crew 🤌🏻

@JohnsonMotorsports Год назад

I appreciate that!

@yoBradyO11 Год назад

Bro i was just asking this question on the group's on Facebook lol. Then i came across your channel! I'm going to buy one of these cheap $300 eccentric shafts and give it a whirl! I've been living with my valvetronic motor tripping since 2018

@JohnsonMotorsports Год назад

Glad I could help! Should have part 2 of the video released this weekend.

@nathanbliss6788 Год назад

also consider doing the motor at the same time as the shaft because they will have reciprocating wear areas... good luck, i watched your previous videos on the subject and they are good..

@JohnsonMotorsports Год назад

That's the plan! I went ahead and swapped out the valvetronics motor as well.

@FiefysLashes Год назад

Omg so stoked ur going the f55 turbs 💪🏻 Can’t wait for that!! As soon as they stocked I’m on board too 🎉 All the best man 👍🏻

@JohnsonMotorsports Год назад

Thanks bro! Yeah, I really excited! I just pulled the stock turbo off earlier today. F55 should be delivered tomorrow.

@@JohnsonMotorsports Do you have the link to the eccentric shaft that you used? I have a early 2010 n55.

@nathanbliss6788 Год назад

you should replace the needle roller bearings and their shells also, they are not expensive but will definitely have wear in particular areas that will cause premature failure of the system. trust me ive done a few of these

@JohnsonMotorsports Год назад

Yes sir. Got a set from BMW and installed them with the new shaft.

@ShawnPier 6 месяцев назад

Are you saying the shaft doesn’t need to be replaced if you replace the needle and rod bearings, or will the shaft need to be replaced eventually anyway?

@JohnsonMotorsports 6 месяцев назад

@ShawnPier I think the shaft will most likely need to be replaced. I replaced mine.

Yes, a regular aluminum bolt.

@januelespinal6328 Месяц назад

Hey how's the eccentric shaft holding up from Alibaba? Could you send me the link?

@legoman911 Год назад

As always great vid 👍🏻 do you think the wear on the shaft could be from a lack of oil from oil squirter ?

@JohnsonMotorsports Год назад

It’s possible, however it could be due to oil change intervals as well. I picked up my car at 125k miles and the Valvetronics was already disabled at that time. So I’m not sure.

@Swag.864 4 месяца назад

Idk if u mentioned it on ur video but wat codes pop up on you before uchanged out the shaft?

@rafaluiz1679 Год назад

You will definitely fell more butt power after that swap.. The eccentric rotating more freely will cause faster rotating and a more light camshaft that equals more air(Everything that is more light equals more power...). After that repair on mine, and changing the DME that fried because the eccentric errors..

@JohnsonMotorsports Год назад

Dang! Glad I didn't end up having issues with my DME.

@SPADED707ish Месяц назад

@JohnsonMotorsports why did you have to remove those caps so slowly? Is it because of the tension they’re under? Sorry if this was already asked, I didn’t see this question, specifically.

@JohnsonMotorsports Месяц назад

Yes, because of the tension and to back the shaft out straight back.

@SPADED707ish Месяц назад

@@JohnsonMotorsports sorry, man. I asked this before I finished the video. I saw why you did it when you reinstalled the shaft. Thanks for answering my premature question though! 😅🙌🏼

@JohnsonMotorsports Месяц назад

Hey grant , it’s been about 3 months since you first posted this video , how has your experience been with the eccentric shaft from alibaba

It’s been perfect! No complaints at all!

@jesseboles2234 10 месяцев назад

after doing this job, do you think the shaft needed to be replaced or could you have replaced just the actuator?

@JohnsonMotorsports 10 месяцев назад

Definitely needed new shaft. I had tried multiple actuators.

@rogerjocom6788 6 месяцев назад

doing the same thing right now using your guide, but before I proceed with my wrenching. does the eccentric shaft have to be in a certain position before removal and also during installation?

@JohnsonMotorsports 6 месяцев назад

The BMW service directions advise to rotate the eccentric shaft to the minimum stroke position.

@ademfeka9633 Год назад

I find a eccentric shaft on aliexpress for 185$ and it saying 2 years warranty, but i want to ask do i have to program the new valvetronic or is just plug and play ?!

@JohnsonMotorsports Год назад

After you install the new essentric shaft you will need to run a Valvetronic relearn procedure through Ista.

@ademfeka9633 Год назад

@@JohnsonMotorsports thank you for answering i see on bimmerpost that after install you can switch ignition on and within a space of 15 sec depress the accelerator pedal down to full throttle 10 times and then valvetronic motor wil start programming itself !!!! Is that true or i need a pc program to do the insta.?! Thanky you for replying

@JohnsonMotorsports Год назад

@@ademfeka9633 Honestly, I’m not sure. I’ve never given that a try. Can you try now and report back?

@lookerxie6764 Год назад

Hey Grant, can you share what valvetronic codes are you seeing that lead to your replacement in this video. Thanks!

@JohnsonMotorsports Год назад

The main code is was getting was: 135704 - Valvetronic system: Warning threshold value, feedback control deviation exceeded.

@zlord1199 Год назад

I wonder if this issue is common in all early model F10 535i. I have 2012 model at 135k miles and mine is completely stock. Been wondering if my valvetronics and shaft will need replacement eventually

@JohnsonMotorsports Год назад

I’m honestly not sure. I would think If you stay on top on making sure the worm gear is lubed properly the essentric shaft would be good.

@f4rshigatsu680 5 месяцев назад

Hey I hope someone can help me. I did this 1.5 years ago without the special tool to open the springs like in the video and now i have the same problem again ... can it be because of that?

@JohnsonMotorsports 5 месяцев назад

I would think that is unrelated.

@samathman3937 9 месяцев назад

Do you know how difficult it is to replace the eccentric shaft on the N52?

@JohnsonMotorsports 9 месяцев назад

I believe the installation is similar to the N55.

@nicksteeb Год назад

I have an 2011 e90 n55. Valvetronic motor went out at 106k miles. How many miles did you have on your engine when it started skipping teeth?

@JohnsonMotorsports Год назад

Man, I’m really not sure. I purchased my car at 125k miles and the Valvetronics was deactivated.

@nicksteeb Год назад

@@JohnsonMotorsports ok thanks. I've got a 140k on mine now. Just did rod bearings, oil pickup, water pump, thermo, coolant hoses, wheel bearings. Going to see if I can get to 200k. Keep up the videos!

Valvetronics error codes and getting smoking at idle when the eccentric shaft jumped teeth.

@patrickconway2587 6 месяцев назад

what problems were you chasing by the way? i have alot of problems in the ~2500rpm range where i get misfires and sometimes the car will shut off after not being able to recover from them. i get valvetronic codes sometimes after it starts back up but not every time.@@JohnsonMotorsports

@SmileIso Год назад

My X3 N55 2011 have the doom fault code , 101F01, air mass plausibility fault. No leak found after smoking the engine, EVAP procedure (15mn idle with purge valve disconnected) done several times, I have rough idle as well. When I disconnect eccentric shaft motor on the top, idle is perfect, the car run perfect. I think of replacing eccentric shaft and the motor but still don"t see the relation between this eccentric and the fault code 101F01. There is no eccentric fault code stored in DME, I have reset valvetronic adaptation and run the 450 cycles several times, no luck. Oh one precision: The 101F01 does not show up when I disconnect eccentric motor connector. When I disconnect purge valve as well.

@lookerxie6764 Год назад

Hey Smile. I have exact the same car as you do, and also the exact problem you are having! While you are having the 101F01 error, are you experiencing any rough idle? I do have rough idle issue and misfire on cylinder 2...

@lookerxie6764 Год назад

I think when valvetronic motor is disconnected, the eccentric shaft will stay at its maximum lift thus more air will be allowed into the combustion chamber, and reduced pressure in intake manifold. Idle at this point is controlled by throttle body I believe. In such a case, both rough idle and 101F01 error are worked around. My car is able to adapt and smooth out with valvetronic motor connected once the following error message shows up: 133710 - Valvetronic, Eccentric Shaft Adaption Lower Stop Attained. However, if I clear fault code or reset adaptation, the rough idle and 101F01 comes back. I think valvetronic and eccentric shaft somehow still play a roll in our issues.

@@lookerxie6764 And yes, I have rough idle, mileage drop
