Xhorse and Autel which is better to add key Audi encrypted BCM2? Software version 0711 is very risky.
You will need xp400 pro. XP400 will not read bcm2 encryption. XP400 Pro has some advantages over xp400 might look the same but it reads more chips and unlocks locked keys etc.
Autel works fine on encrypted BCM2 but requires using diodes (Normal rectifier diodes, 1N4001-1N4007).
Here is a programming instruction.
But Autel has a risk of breaking BCM2.
Here is an example:
Tried to read encrypted BCM2 with IM608 and XP400 Pro. It identified correctly, read some data, tried to calculate and came back with network error and now the BCM is dead.
BCM2 recovery will not work as the file Autel saved is ‘not supported’.
BCM part/hardware number
8K0 907 064 KE, 0711
It read a 1kb data file and 41kb immo file and then lost communication after that. Autel didn’t make a backup as it died in the reading process.
Time to get a new BCM2. Buy a new BCM and dealer key and ODIS.
Xhorse VVDI2 or VVDI Key Tool Plus all day for those. Xhorse is much better for VAG.
Vvdi2 or Key tool plus with BCM2 adaptor. No soldering is required. Works perfectly. Done BCM2 AKL with in 30min all job.
If car won’t crank, boost the car to get more that 12v and learn the same key again. Also clear dtc after learning.
Chek example:
Xhorse VVDI Key Tool Plus Read Audi BCM2 Data without Soldering
VVDI2 and VVDI Prog also can clone locked BCM. Just need to buy this same HW /SW, load service data, and read it again and decode.
