A:You can use the 754J key currently on the market.

A:The adapter only charges a one-time fee, and it will be free for future use, and no points will be deducted.

A:It is planned to ship in early September, and it will be shipped in
the order of booking submitted by the agent, first-order first-served.

A:Because there is currently no third party that specializes in
cooperation, you can consult a third party who can provide this service.
The specific cost is negotiated between you and the third party.

A:It is more convenient, as long as people with a little hands-on
ability can do it, it is usually hidden behind the protective pad of the
car trunk, which is a buckle plastic box. You can take out the BCM2
circuit board by gently prying the buckle.

A:The Audi kit-free solder-free adapter kit consists of 6 parts. Its
core component is the orange BCM2 adapter. As long as this adapter is
available, the BCM2 data can be read by soldering wires, but the adapter
is not currently sold separately. In addition, in order to prevent
welding damage to the BCM2 computer, we strongly recommend that novices
choose a solder-free adapter.

A:No. The 2013-2018 A4L needs to read BCM2 data through the Audi free
soldering adapter, while the A4L before 2013 can obtain BCM2 data by
OBD, and does not require a set of data.

A:VVDI2 will also upgrade the software to support this function, while
it has to work together with VVDI Prog for reading BCM2 data.

A:A6L can't support yet. Currently, it only supports A4L, A5, and Q5 all key lost.
A6L supports reading BCM2 data in the all-lost state. You need to find a third party to synchronize the data.
