A4 B8 BCM2 file repair

[darrenhyland]

Can anyone check out this flash and eep file from a 2011 Audi A4 BCM2 module 8K0907064E. Battery went flat with key in ign and data corrupted with no ign etc working. Tried a hard reset etc but no joy. Attached is flash from D70f3380 and eep 95320 both read with vvdi prog. Elv was also acting up so if someone can check my dumps for errors and repair then I would be very greatfull. Thanks.

Eazy bro. Get a BMC2 unit from scrap, pair with the car, make new keys, done.

Can I match used bcm offline.....I have vvdi2, svci2020, vcds etc or can I write eep and flash dump from other module to my bcm2 and then virgin and match?
