Xhorse VVDI2 read dash, precode CS to key, add keys

Here goes an interesting topic... About Xhorse VVDI2 read dash, precode CS to key, add keys to VAG group vehicles.

All begin with a conversation..

Puzzles from user A:

Im new to VVdi2 so still learning what it can do .

have a citigo 2012 key to do.

dash is 1st 920 960 g I think its the same as the up and mi . 

I think its a marelli dash if I select the only marrelli from menu it does read something and the is hex in the window but then says fail. I struggle to know which dash type to select. 

Q1 will vvdi do this
Q2 which dash to select.
Q3 if it cant do it can I read epprom precode and use vagcom. 

any other tips.

Suggestion from user B:

Read dash ok as mm7 mk6 golf.

(Bug 1 failed to auto detect this dash)
Pre coded CS to key OK.

(Bug 2 failed to add key with any of the three methods listed.)

add key to dump method actually killed dash

and all keys failed to start.

Needed to put Back original dump back to dash to get key 1 to work again.

Finally solved by manually editing dump and overwriting key 2 (lost key) with the ID of the new key. It's ID appears in the dump in 3 locations simple search and replace worked well. Happy days. Remote added with VCDS. 

Conclusion:
It's my first run out with xhorse vvdi2. This is going to be a really powerful tool when the bugs a sorted. Bit scary to used while it is still buggy. Hope this help someone
