E39 auto - oil change?
Discussion
I have a 2001 525i auto with nearly 50k miles on it. I know the gearbox and diff are sealed for life but does anyone recommend changing the oil in either or both? I ask because the auto box died on my E46 and was the better part of £2k to get refurbed/replaced so I'd prefer to take preventative action if it'll help.
Blimey this one does come up often
Bit of a how too (specific to E38 with a sealed for life box)

Oops! I searched for selaed for life going back a year but didn't get those. Thanks. Just spent 30 mins reading them and I'm still undecided. 
The idea of taking it to Dortmund is daunting at this time of year, but it sounds like the preferred option if I can justify the time. I have a good indy so will probably get him to do a fluid change if he fancies it then pop on the ferry next spring.
... maybe...

Thats the problem - strong opinions on both sidesLordGrover said:

I think the key aspect is making sure the damn level is right - I did several completely cold checks before I was finally happy the level was right ... maybe... Knew I'd find this link eventually which might be useful for those considering an oil change

Jeez !!
Ok, Bm say they are filled for life, if you're Ok with that then fine....If not, get to a good indy and get the oil changed, if you need the piece of mind then it has to be worth it!
Had several Tiptronics, none have ever given any problems and i have never changed the Transmission fluid in any!
However, my personal opinion is that if you have ANY reservations on the scaremongering about these Gearboxes, then have it done (particularly if the mileage is high and you intend keeping the car)
I suppose if your care & are enthusiastic about your motor, then you will have it done regardless .
