Good new B&Gs... The 511B Error code the MSD80 cars are getting is a know erroneous fault caused by an error in a diagnostic software. SI B 24 11 06 Below is the SB.
So, for those under warranty, if you think your dealership is smart enough to know you are running the Alpina code, don't flash. (just kidding) It stays in you flash history, but very unlikely anyone would ever notice because it just looks like a normal flash. My car already has three different assembly numbers applied to the EGS. Two from the dealership and one from me . I actually flashed back to OEM today to see if the code goes away and ended up pulling off to the side of the road and flashing it back because the OEM code sucks so bad I couldn't stand it.
