How to change F30 BMW Differential Fluid

[@rickhundley3465]

Like others have stated. You've got to do a transfer case fluid change next! Your videos are the Best!!

[@joeomerta]

Can you get an oil analysis of the diff fluid? I'd be curious to see how "lifetime" fluid holds up after 30-50k miles

[@acrdn2tc]

Can you do a DIY on changing the transfer case fluid?

[@thejungatron6792]

Yes! I was planning doing diff fluid change this weekend. Good timing. 15 at 50k 335i RWD

[@stoss-11]

same lol

[@NJFPV]

I installed a Quaife about 10,000 miles ago. The one thing about having a dual purpose drain and fill plug is that you can't ensure that you get all sediment out when changing fluids. I'll be doing a change soon, but part of the process i go through will be getting a magnet into the bottom of the reservoir to find and remove any metal dust. That's the shit that wears everything down over time... Going to be a pain with the angle of the port though...

[@kasunwanni]

Always support Bryan! Learned a lot from this channel. So much knowledge :D

[@morbus74]

I've watched now your both videos, front and rear differential fluid change and i'm definitely gonna do those to my F30....although it seems really easy thing to do, thanks anyway for really informative videos 👍

[@MoeG96]

Hey Brian! Ur the best honestly I’ve been maintaining my bmw thru ur videos and im always more than satisfied with these visuals and instructions! Was wondering to, haven’t found a video on DIY transmission fluid change.. my car is at 160K and i was wondering if this is required to be replaced atm.

[@John-qc1zv]

GL4 75w85 or GL5 75w90 ? BMW say one thing and Redline, Castrol and LiquiMoly say another thing. Is it different from a RWD than AWD ?

[@maxwellkeeling3781]

If there is one thing Brian has shown us is that the F series is quite easy to work on but the OEM BMW parts are $$$ 😂. You can use other 75w90 full synthetic diff oils that are significantly cheaper (can usually get 1qt of top branded oils on sale under $20 CDN) but YMMV and the BMW stuff is high qualitia either way. 50+K miles is a long time and $140 US isn't a bad investment either.

[@kamma0618]

Would love to see a transfer case fluid DIY.

[@Sielent13]

Oil inlet screw opened, small doctor syringe taken, sealant injected in and oil about half a liter. The whining became less, only when downshifting is it still there. 3 4 5 6 you can't hear anything anymore in 2nd gear the noise has become less and in 1st gear you can hear it even louder at full speed, the jerking at 140 km is gone, which I had before at 120 km

[@RbNetEngr]

Thanks for producing another great DIY video. Man, what a bummer that the F30 diff doesn't have a separate drain plug. I mean...SERIOUSLY, BMW!!! BTW, that's a really cool light that you're using underneath the car. What is it? Is it just to provide better lighting for your videos, or is it something that would be good in the garage for the DIYer?

[@brianthiem9208]

would you guys be whiling to make a video on a big turbo n55 engine? or show the 335xi f30 a more trying to get ideas a bit for myself

[@Coslin]

Easy Peasy! Nice work!

[@highendtrends3508]

Great channel! Super helpful!

[@Drd4all]

Great video as always guys 👍🏻

[@hienhuynh9279]

Great instruction DIY and detail

[@stoss-11]

GREAT VIDEO I NEED TO DO THIS ASAP

[@minino1237]

Waiting for the transfer case fluid change video

[@that_ninja_jun]

How much gear oil did you end up using? Looks like about 800-900mL unless you guys edited and cut to the 3rd bottle?

[@that_ninja_jun]

For anyone wondering; i just did this job on my 2016 435i GC. It took about 800-900ML, so just a bit less than a 1L bottle. I bought 2 bottles just incase, but have about 10-20% left of 1 bottle and an untouched bottle for the future

[@Mcstikman]

@@that_ninja_jun Thanks, was combing the comments looking for this info👌

[@seollenda]

do we need to change the front fluid too

[@chrisbraganza8481]

Can I use Mobil 1 full synthetic 75W90 for the rear differential in my 2013 BMW 335i with an N55 engine instead of the expensive BMW 75W85 fluid?

[@JVR_Funwithdesign]

Yes, I used Redline 75W90 in my F22. As long as it's GL5 and in the weight range you are fine. The one fluid that I stick with OE is the transmission. I used BMW manual fluid and it was pricey but it's not something you have to change regularly.

[@georgesunnyt]

@@JVR_Funwithdesign it needs to be gl4 not gl5

[@dcmoore54]

Did you say about how much new oil it took? Sorry if I missed it in the video, asking for an OCD friend.

[@CastroJordan]

lol I believe the rear is about 1.5L and the front on xdrives .5L, but I would type your vin in at realoem.com and look it up to be sure

[@cre8tivegarage157]

Very informative content keep it coming very interesting

[@kenkobra]

Just an FYI to all. Buy your BMW parts that KIES doesn't sell from BMW dealerships on the East Coast as they are much cheaper than the West Coast. It's still cheaper if you include the price of shipping.

[@morbus74]

Hey Brian! Can you please tell me, is the same oil suitable for front AND rear..? BMW gives a different part numbers for front and rear fluids..but is it the same stuff anyway?

[@supremegt]

Nope it’s different

[@CastroJordan]

I wonder how long it drained out after plug was removed, because some guys refill until it overfills then wait until it stops draining the extra fluid. But clearly from the factory there is more fluid than that. In reality we should overfill and immediately get the plug back in trying to lock in that extra fluid instead of letting it settle right below plug.

[@gregcollins5865]

Diff oil expands over time.It gets carbon build up, normal molecular expansion, metal, etc.. So even if you let it drain for an hour, you will get plenty of drainage when you pull the plug in a year.

[@jojorodriguez3489]

Is it basically the same for g20? Make a video!

[@NinjaTactiks]

Silly question, but could you reuse the same extractor that you use to pull the old stuff out or should you swap a fresh one in to avoid contamination?

[@peterurban2650]

I think there will be very low percentage of contamination, but in order to have 100% new clean fluid I think you need to use some kind of machine which is used for automatic transmissions fluid change.

[@HoneyBadgerFarm]

Remember as well there is old fluid left in the diff as well.

[@BeeShopcs]

Hi, my car already 100KM 63Mile, do you advice to change the diff fluid?, known that dealer did not do it, as they said, its lifetime

[@CorbinWilliams]

My vehicle has 180,000 miles on it, never thought I could change the diff fluid until I found this video… Is this something I should do, or avoid it now that the vehicle is at such high mileage?

[@spacemonkey7461]

Do it

[@BapFootballHD]

just do it!

[@jetrider7558]

Just do it. She will run smoother. You will feel it.

[@CorbinWilliams]

Update my vehicle now has 220k miles on it. 2011 528i with the N52 straight-six.

[@josephbrown3647]

What are good options for Diff fluid other than the bmw branded one?

[@kenandrum5613]

Redline

[@magnetman3t725]

Would this procedure be similar to the GR Supra rear differential???

[@DrGrinsp00n]

What milage do you recommend doing this?

[@Drtbiker88]

Yeah can you do one to change the transfer case fluid? Seems like a pain in the neck

[@tackycomrade]

I have had my m performance LSD for about 4,000-5,000 miles now. Would you recommend I change the fluid soon as it has now been ran in?

[@TheDavididoff]

On a new LSD I would have changed the oil after 500-1000km. Then every year or 15-20K km. Because an LSD has lamella packages, which wear over the time. Not like an open Diff (shown here in the Video).

[@tarricknicholson6300]

hey Brian my f30 oil change and still showing low oil add 1 quart.

[@ShamoB58]

Redline is a good oil??? Works??

[@marwin56]

Is this the same process for a 6spd?

[@marckevinnn]

Anybody using Redline 50104 75w85 on front and rear diffs? any concerns

[@aalexx1900]

How many litres did go in?

[@steevynovirus_f3099]

How many quart i need for a 2015 328i xdrive

[@parthdinubhai]

Haha when ur at 70k miles and you couldn’t find a recommended service interval till now at 50k miles 😅

[@bosstone2004]

Will this be the same for an F36? I can’t find any videos for an F36 specifically

[@supremegt]

Should be

[@timothymountain7868]

My car is 5 years old and just passed the 15k mark. Was going to have this done but seen as I have such low mileage, I won't bother.

[@gidz001]

Thank you

[@musialik1997]

Are you going to change transmission oil in 8HP? :D

[@accordgris]

there is a bunch allready on youtube of those video's

[@maxwellkeeling3781]

@@accordgris but we want the BRIAN version :P The only other 'professional' one out there for similar services is FCP Euro but I think we are all here watching Brian's videos because...Brian haha

[@cheetse91]

Can someone confirm if it's 45nm or 60nm??

[@nys1032]

Thanks sir

[@BasRikken]

16 or 60 nm?

[@maliktennhue7594]

Never see you do a diy job and manual transmission

[@readmposter]

Finally! 😩

[@javiergandica634]

What do you think about the CTS Turbo Bov for n20 mottors?

[@xxthe_remedyxx5296]

Should the car be leveled for this? If you do this on ramps with the car tilted forward, you're going to fill the case with way too much fluid... Is that a concern?

[@ahmadshaha2481]

👍🏻👍🏻

[@leekeenwah307]

How many little

[@MegaTony805]

F32 2016 110k miles think it will be the first fluid change lol

[@philliptownsend2829]

Never this been early damn

Of course jesus works on bmws

Almost $70 for a little over a pint, absurd.

Is this a gear box oil change?

[@Firstmajortomlikestoticker]

diff fluid is dead Animal and Plant oil that is why it sticks...LOL
