Dealer Re-programming entire computer system? Concerns?
Ok, so, when I bought my M5 a few months ago, the guy only had one of the keys - a Comfort Access key. Even though he assured me the other would show up, I went ahead and bought a new one a couple of weeks ago. Well, apparently it has to be programmed at the dealership (Comfort Access portion only), as they said that you can only have 2 active CA keys for the car, so they have to deactivate the one missing key, and program the new one in. Well, I've been there twice now, and both times they have been unsuccessful. My SA today told me that it they were having trouble deactivating the old key. He then asked if I could schedule another time to bring the car in, drop it off (and leave it - i've been staying and waiting the last 2 times). Said he would get me a loaner, but that they needed to completely reprogram the entire computer system - all the systems - basically start from scratch, with NO keys, and then add the two keys in. Said that this would be an upgrade to the entire system. So, I know others have taken their cars in to have the computer 'updated', and I assume that is what will be happening here, but I have a couple of questions:
1. Any concerns I should be aware of?
2. Is there any benefit (other than fixing my key situation) with having this update (my car is MY 2007). As far as I know, it hasn't been done before, but don't know that. Just wondering if things like SMG Updates or IDrive updates will be done.
PS. I told him to surprise me with a good loaner. At least something interesting.
