transmission fluid change even possible in E90 cars...?
...from a practical standpoint, that is. (Disclaimers: I have been working on various European cars, mostly Porsches, for 20+ years; please, no commentary on whether it is wise to change fluid at all/at whatever mileage/ what fluid to use if you do, etc, I am familiar with the controversies over the "lifetime" ATF in these and other cars).
I have an 07 328i automatic with 48k miles I bought a year ago as a CPO car. I planned to do a partial fluid change today, with a new ca$e of Pento$in ATF1 $itting at the ready. Having done this type thing more than a few times in other cars, I scoped out where I was going to put the new fluid in before draining the old. Unfortunately, the trans in my car looks nothing like the one in the DIY guide here. The typical 17 mm internal Allen socket plug was nowhere to be found. I can see what is probably a black filler plug at the rear of the unit (a protruding, mostly-round-with-two-flat-sides type), but it is mostly blocked by the rear mounting bracket for the trans. The impression I get is that BMW, like so many other manufacturers, has marched one step further towards making these cars unmaintainable by the home mechanic, even compared to the generation car in the DIY. I can see getting this done by perhaps supporting the trans from below the car, and disconnecting the rear support structure. But man, it shouldn't be this hard. Any constructive thoughts?

the at tranny filter is magnetic so no need to change it so no need to open the tranny pan. Do a flush ( inlets at the oil cooler so you can change the fluid in the torque converter too ) Did it a a BMW shop $300 tax in.

Are you sure it's 100% magnetic? It doesn't contain a paper filter element? Also, if so even magnets lose their pull.

Oh, I'm not going to give up. I simply hoped they would have given a modicum of consideration to normal maintenance, their laughable service schedule aside. They clearly have set this unit up to be sealed for its service life, which flies in the face of mechanical logic and the known breakdown properties of synthetic or conventional fluids (and, even more concerning, potentially means the service life is shorter than in needs to be, given the variety of service harshness the car might see.) I'll end up jacking it up higher and taking a more serious assessment of the rear bracketry and how it can be removed to get at the plug. |

Any Luck Yet?

Any luck yet with finding a way to reach the fill plug? This is my first post. I have been lurking since March when I got my first BMW ('09 328i, auto, sport, premium, xenons, PDC) with 8,000 miles on it. I'm up to 15,000 miles now and would like to do an ATF change at 30K along with the coolant and differential oil for the same reasons you have cited. It seems like the coolant and diff should be straight forward but the ATF is the issue. I cannot find a lot of DIY applicable to the later models, so interested in what you have found. |

Seriously do yourself a favor and spend about $125.00 and get the Bentley Service Manual for your car. Everything you can think of doing will be in there and its going to pay for itself easily. If nothing else, when you take some obscure thing apart and find it was removed the wrong way and it's $200.00 for a new one.
