Issue with E70

[MONAX]

Hello everyone!

A couple of weeks ago I traded in my e53 for a new to me e70. Love it, It is a 2008, space gray metallic, black interiors, it's a beauty; however,

For the last couple of days it has been doing something that has me worried... about 90% of the times when I start the X there is a loud noise coming from underneath the X, almost like 2 metals banging together pretty hard. Exactly at the same time, there is slight lurch forward that is noticeable to my and my passangers. Now I have read on some of the postings here about the famous lurch forward, but haven't read a post that correlates it with the noise (almost coming from the tranny, which is kinda scary!). Also, when driving around town when I am coming to a stop most of the times the X comes to a stop but right at the very end it lurches forward again (I believe the some of the posts I found on the search talk about this)...

From the posts I read, the fix for the lurch is to bring it on the dealer and it would be a software update? is my understanding correct? or is there something else?

Also, has anyone experienced the noise I am talking about combined with the lurch when you start your X? Hopefully someone out there can relate.

Thank you for your time! appreciate your feedback.
