F80 M3 / F82 M4 first (1200 miles) service guide - what's required...

[sky03]

the diff oil is really problem right now. No one can be sure about this. On ETK it shows: 83222365988 which is synthetik MSP/A but older M cars use SAF-XJ.

Some of you ask can it be any problem if we put wrong oil.

Here is my topic, I am having a problem with the diff and it seems like they put the SAF-XJ. I am not saying that this cause the problem but I am having a problem..

IF a BMW dealer did the service... even IF they used the incorrect oil... BMW should stand behind your car and your diff. Even IF they need to "good will" a replacement diff. Sounds like you might need to get a regional service manager involved with your case.

Indeed the latest oil for the M4/M3's seems to be: p/n 83222365988

FINAL-DRIVE GEAR OIL MSP/A

Looking at your vibration thread... the firstthing that came to my mind was the cf driveshaft recall or even a bad center driveshaft bearing. I really don't see how replacing your diff fixed your vibration issue. ? Then again... there have been quite a few M2/M3/M4's with the diff's making that "crushed soda can" sound from bad ring bolts in the diff's inners.

PS: Don't forget to do a new break in on your new diff - and change the diff oil after 2K kms. Not high speed runs or launches until 2K kms.

Thank you for your concern. As you said I also didn't figure how diff makes it but, We checked center driveshaft bearing, before replacing the diff.

It seems like long process is waiting me. They said that BMW does not accept the "good will" cause the car had software tune, even this issue has no connection with the engine. Also the authorized service which made the mistake, looks like will try to deny/object it. Probably we will go to the court..

Always BMW and service deny and object these thing to extend the process, if car owners make even little mistake they just blame and deny the guarantee.

Like on this situation, if the car owner do this oil change mistake, they immediately cut the guarantee, but when the service do this, they just do nothing..

On the other hand, the car is in the other authorized service right now and they charged me nearly 1200 dollar to just say the "the problem is diff" even I said them this in the first place..

Now if I will have to change the diff + shaft, I should pay the nearly 8500 dolar...

There are a lot of different part numbers floating around for different parts, can we confirm the latest part numbers for the 6mt fluid, rear diff fluid, and the drain/fill plugs for each?

I need help with my 1200 miles service:
I had the service done this morning and the dealer used part # 83222357992 (SAF-XJ-832514) diff oil. From what I read here there is another oil part# 83222365988. Did the dealer use the wrong oil? should I take the car to another dealer and request the diff oil to be changed? Tx

Castrol SAF-XJ is fine to use. But most US dealers will use SAF-XJ+FM. The FM stands for friction modifier and will reduce/eliminate diff chatter while parking or at low speed turns. So it really depends on whether your diff is making noises and IF that bothers you.

One note... once a car uses the +FM fluid... you always have to use it in that diff. Most euro cars don't get the +FM fluid. I suspect that the +FM fluid makes the LSD less effective(at low speeds) but that's just a hunch.

I believe you are correct in saying that adding extra FM fluid reduces the effectiveness of the clutch pack in the diff, making the diff slower to lock up. I changed the Castrol SAF-XJ with +FM out of my 2013 E92 M3 for standard Castrol Castrol SAF-XJ and it made a significant improvement in traction.

Now I have the same problem with my 2017 M4 with poor diff lock up and I am tempted to swap out whatever oil BMW used at the 1200 mile service and refill with standard Castrol SAF-XJ and see if that gives any improvement.

I don't think there should be any problem with changing from SAF-XJ with +FM to standard SAJ-XJ. The standard Castrol oil already contains friction modifiers, BMW just chuck in extra to quieten down the diff pack to stop people complaining about the harmless noise that some diffs can make.


EDIT: I swapped out the standard BMW Final-drive MSP/A gear oil this afternoon and refilled with Castrol Syntrax 75W140 (the new name for SAF-XJ, changed years ago).
Blimey what a difference it makes, now the diff locks up *before* the DSC can interfere...gives way more traction and thus acceleration in the lower gears.

Does anyone know were I can buy the correct oil for my M3 for a good price besides going to the dealer?

Walmart sells 5qt jugs of LL-01 Castrol 0w40 for like $25. Probably the cheapest.

[Ddoherty]

thanks for replying Gatorfast, If I use Castrol won't that void the BMW warranty if I'm not using BMW oil?

Thanks

Nope, the BMW LL-01 certification (which numerous brands carry) is what is important when it comes to warranty.

[Ddoherty]

Awesome, thank you so much for the information!!!

For MY2018, is the 1200 mile service FREE?

I believe all services are free in the USA. Over here in Germany it runs about 700 euros for the 1,200 mile "break in" service. IF you have it done while in ED... you can pay for the service(as long as it was done by a BMW dealer over here) and then submit your repair bill to BMW NA, once back home in the USA.

I just took my car in today for the BIS and they said they don't change the diff fluid anymore...

Seriously? Can someone else confirm?

[Vectors2final]

Seriously...

I would love to get a real answer from someone. I might call BMW NA and ask, but I'm not sure how far that'll get me. I'd love nothing more to slam a service department for lying straight to my face when I asked the question.

Not to mention scraping my front CF lip while they drove it four miles. It's my fault for not doing a walk around before and after with the SA present. Luckily it's not noticeable, but if anyone is going to eff up my lip, it should be me.

I just scheduled my break in service for next week (2018 M3). My SA specifically said they would be changing the engine oil and differential fluid.

Might have to make a call and solve this another way.

[Vectors2final]

I stand corrected.

There was an additional page in my service paperwork that I didn't catch. According to that paperwork, my fluid was changed with PN 83-22-357-992 SAF-XJ.

I don't understand why the SA would go out of his way to lie to me? Deflection for an answer he didn't know?





Upon further review, I inspected the diff and it appears that the fluid was changed.

Probably just too lazy to check on it and give you the quickest answer that came to mind. Poor customer service. Give a big : on your satisfaction survey.
