7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Can SW be restored to original Ver after an update?

After a software update, can the original version of the software, prior to the update, be restored? This in case the new software version causes problems.

I made a reasonably hard low speed left turn and I got this triangle warning with the words "drive Moderately". THe next time I started the car the message was gone. (Steering fluid was full)

Indie using analyzer said "steering angle sensor" needed to be replaced. Warranty company said its covered but wanted software update 1st to see if that fixed it. Of course warranty doesnt pay for software upgrade. Dealer wants $180 to update software. I dont mind that but they say they cant restore the original version after the steering angle test. Also they say that sometimes all sorts of other incompatibilities with modules occur when updating software that I would have to pay to have replaced.

Is this BS?. CAn software be restored to prior version. I dont mind paying the SW upgrade, but if there is a problem Id like to restore back.

Any insight would be appreciated. And if restorable, is there documentation I can point to to show the indie tech?
