Vytas Vytavicius:

Tango only need 9s12 eeprom to make and program key

Mark Taylor:

Vytas Vytavicius:

read Motorola 9s12 eeprom and you can programme with Tango

Mark Taylor:

I read it with VVDI

Vytas Vytavicius:

VVDI prog?

Mark Taylor:

Yes with wires…Eeprom

Vytas Vytavicius:

and when you put in Tango it says encrypted

Mark Taylor:

Yes it says need working key or ISN

Vytas Vytavicius:

i never had that but try to go on Tango forum im sure they found whats the problem

Mark Taylor:

I’ve been told it BMW updating the CAS unit

I just bought Merc clamps to put EIS in do they work

Vytas Vytavicius:

probably it been updated to latest ISTA-P, normaly i programme these with Avdi,not sure about claps for EIS,but i think the best tool is Smok Jtag to read CAS and EIS

Mark Taylor:

Thanks is there any thing to help that better to put wires on bit worried doing this

I have Avdi but if it’s CAS3+ start downgrading it

Vytas Vytavicius:

yes with Avdi BMW on line you can do, but battery charger put when downgrading

Mark Taylor:

Yes i know this my eyes are dodgy so putting wires on a worry

Vytas Vytavicius:

for me personally i use Smok Jtag and never had any problems to read, especially Mercedes EIS its to easy

for older Mercedes EIS its a bit tricky

but in uk probably its very rear older Mercedes

Mark Taylor:

Yes the solder so close together

Is VVDI2 worth getting

Vytas Vytavicius:

so do you done that BMW key, key was lost or just spare key, VVDI2 Xhorse its very good tool, i newer sell even i have Avdi

i have some cases than Avdi failed and VVDI2 done in secs

Mark Taylor:

What price of this

Vytas Vytavicius:

i seen one on on ebay second hand but full full 1500pnd, that is a very good price;

But i recommend you to have a brand-new one for sake of security, and professional tech support is very important. You can use Google and have a site xhorsetool.com and the like
