My 2007 E60 has just had a battery replacement. I did not go to the dealership, but instead when to a specialist battery supplier. No problem with the new battery. HOWEVER I rang the dealership today to ask them about todays announcement of a recall for a battery terminal issue. I mentioned that I had just recently purchased a new battery and they told me that I had to return the car to the dealership to have the new battery linked to the car's computer so that the car recognises that a new battery has been installed. There was mention that the charge rate will altered after the car's computer recognises the battery.
I would like to know whether all of this is true, and if it is, what is the point? I'm all for technology but you would think that the car would be able to recognise that a new battery has been installed.
I wouldn't be Suprised. The iDrive system in the E60 is quite complicated. The reason BMW states your supposed to mate the battery to the DME Is that it has a varying charging strategy for the battery and over time apperantly that changes as the battery gets older. A new one should work fine without it, but might not last as long. I would hate to have to pay $300+ for a new battery, but I've read some dealers still charge $100 for the mating.
I miss those days. That's why both my vehicles are from the 90's. The best BMWs were from the 90's hands down. That and the E30. Even my wife's 2001 minivan is more complicated and has more sensors then my 98 E36.
