So then you'll have to pay for a vehicle update, unless you can blag it under some other warranty issue. (if you're in warranty)....
Your sig says you have an E46 is that right?
Oops I need to update my sig
I have an E93 now!
The other reason I ordered from the dealer is I still have AUC warranty and 1.5 years of service package left to run... 5/2009 build date on my car (pre-LCI) according to RealOEM.
