Cured mine and can cause no harm, give it a few miles to take effect,Did not read all the thread but I assume you changed the filter

 

When I was a member of a BMW X5 forum, someone had posted that "officially" BMW refers to lifetime as being 120,000KM (75K miles). He had even posted an internal document that supported this - in German but translated.
The reference is based on new owners, who tend to sell or trade-in their BMW's before 75K. The brand cares little about what happens to the vehicle after that. Not their original owner - not their problem.

 

I really wish this were common knowledge among all owners, not just the enthusiasts. 75k is a little more generous than I expected.

 

Check the fluid level, change the pan/filter and like was said, change out the rubber bits, the seals between the metatronic and the trans body. All in one shot, so to speak... All inexpensive stuff.

I also use mercon sp, and it seems to work... the dude that I purchased all the new trans parts from recommended it. The guy in California from ctsc,,, can't remember his name at the moment...

 

Agreed.
Probably would have saved many a transmission.
I am using the Mercon fluid, and it has been in my transmission for a number of years now. Transmission has never exhibited any issues from using it either (6-speed). I went through hell with my transmission and the journey was well-documented on the site. Search for my post about critical intel on these transmissions. But that was a long time ago and after I finally figured out what my issues were, I have been a happy driver ever since.

I would like to mention that the metrics used by them in determining the EOL of any particular model does not stop with the lifetime fluids either. At 75K, the plastic parts all start to deteriorate, pot-metal parts like door handles, etc., are fatigued and the rubber used begins to deteriorate as well. Basically, they would be happy if the entire vehicle turned to dust at 75K. This is because they have absolutely no interest in what happens to the vehicle after the original owner has disposed of it. It is the original owner that is their customer - not used car buyers. The only caveat to that is the vehicles they certify used. Those would still be well under 75K mind you but I would suspect that part of that service is changing all of the fluids and maybe even swapping in new engine parts made from plastic that are critical to getting the vehicle to the 75K mark for the second owner. I also suspect that this is not just BMW doing this but rather all Euro and many domestic brands as well. Used car buyers are of little interest to any of them. When I owned my 1985 Porsche 928S, I got to a point where I needed to replace the rotting and leaking power steering lines. They are a combo of metal and rubber. Porsche sold me a set for the princely sum of 300.00 a piece. When I exclaimed at the price, the parts counter guy basically said, just because you landed a 928 for 10K, doesn't mean that Porsche will discount the new parts in kind. We were both laughing about this BTW - he wasn't being an a-hole. Just gotta keep on, keepin' on I guess. We do get to drive high dollar cars for peanuts so there is that. My 2003 cost me a whopping 8k when I bought it many years ago.
