1200 mile service

[VO1M]

Apparently the 1M will require the 1200 mile service like all M cars - probably because of the M differential rather than the engine which is similar to the Z4 35is.

And maybe transmission too?

Maybe because it's also an M car? Why everybody keeps doing as if the 1M Coupé isn't a true M car? And don't come with : because it's not an NA engine...

I think most are finding it difficult to adjust to BMW's move from NA engines.

Felt the same way about NA until I drove the 135i.
Would like to know what is recommended at 1,200 miles for the 1M.

If they do in fact require a 1200 mile service, I suspect it is mainly due to marketing and not necessity. Basically a way to further separate M cars from regular series vehicles.

The different piston rings arguably require a break in oil change from tighter tolerances, but otherwise there is no meaningful hardware difference between a 135/335 and 1M powerplant. I don't recall if the M differential requires a fluid change on the M3 at 1200 miles, although somebody could check this out over the M3 website.

It's not an M car cause it rides to high and the exhaust note isn't right. I'm going to go cross shop a WRX

The 1200 mile service for the M3 includes a change of the M diff oil and the manual transmission oil (http://www.m3post.com/forums/showthread.php?t=265139/), so I suppose there also will be a 1200 mile service for the 1M.

Thanks for the clarification South. The tranny change on the M3 is only for the 6MT as I recall (bad things happened when a few dealerships changed the fluids on the DCT).

I am unclear why the M3 6MT would require a fluid change whereas our regular 3 series manual tranny does not (and in fact there is a written warning on the tranny indicating it is lifelong fluid). I can't imagine the differences are that substantial.

[Dackelone]

^^I also think on the M3 trans you need to clean the trans filter too - when you change the fluid. I don't remember on which trans though!

I also think both trans (DCT and 6MT) need a trans fluid change though. Some dealers just do not know this - they think its only for the 6MT.

I hope BMW would splurge for an engine oil change too @1,200 miles.

I'm pretty sure the DCT does NOT need a fluid change. When the first U.S. M3s arrived there where a number of complaints on the M3 board about transmission failures after dealerships mistakenly changed DCT fluids (since they were unfamiliar with servicing the car).

Anyway, it sounds like the M diff needs a change. This topic is of concern to me since my dealer is far away, and I don't want to have to drive hundreds of miles to simply get an oil change that I can do myself.

Ahh, the DCT transmission oil disaster. You're right, I edited my comment to make clear that's 6MT only. Not an issue for the 1M though.

Yep, the manual transmission filter needs to be cleaned.

There's no problem about changing the fluid of the DCT as long as the correct fluid is used. There were some bad incidents in the early days of the M-DCT where dealers would (wrongfully) replace the DCT tranmission oil and used the fluid for the 6MT.

If it's covered under the free service program, then there's nothing much to worry about except you gotta hope that the techs will do things right. My M was overfilled with oil on that first service because they had no idea how much oil it really need back in 2008. Ridiculous but true. In fact, I was overfilled twice over my service history via 2 different dealers.

YuP! Just did a quick search on the M3 forum and you are right.

I guess the trans filter taht needs to be cleaned is on the 6Mt M3's. I wonder what the 1M tranny will entail for service.

Humm this is interesting because it would (for me at least) put a serious question mark on the feasibility of a European or Performance Center Delivery. I live much more than 1200 miles away from South Carolina and having to schedule a 'pit stop' for the break-in service in the middle of the trip back home would definitely complicate things! . It may be less of a problem with ED but could still be depending on the size of the 'European tour' you would want to do...

I didn't realize that transmissions are so sensitive to the type of gear oil used. Maybe I should stop using Mobil 1 in my chain saw and follow the manufacturer's recommendations.

Manual transmissions are extremely sensitive to the fluid used mostly because of the fiction materials used for the blocker rings and synchronizers. They require a precise lubricant to maintain the proper friction to slow down or speed up the syncro assemblies to engage the driven gears to the main shaft at each shift. This friction matches the driven gear to the speed of the main or output shaft so the "gears" (actually the engagement teeth) don't grind at each gear shift.

In addition to allowing the fiction materials to maintain a precise amount of friction, it has to eliminate friction in the bearings and between the drive and driven gears.

It's also even more critical for the DCT because of the wet clutch.

Well the X5M/X6M's dont require a 1200mile (2000kms) running in service, so im not so sure this will get it either!

Rumour has it that the N54 (is) block in the 1M is a 'de tuned' version of the 450bhp unit that'll find its way into the F30 M3!!! That one will no doubt need the 1200mile running in dervice because of the different internals it will recieve...............to cope with the extra output

[VO1M]

As implied in the begining of the thread, BMW UK have confirmed that it will require the 1200 mile service (dealer bulletin).

OK - thanks! My master tech said otherwise, but if there's a bulletin now......
