Audi Q7 2014 all keys lost

[z786]

Hi, i have the CS PIN and MAC from edc17 ecu
i input those 6 bytes and pin in ezs via AVDI, it lets me read VIN ID and also Key adaptation (login OK) but i cannot prepare dealer key, while reading ecu it gives up, any ideas how to go from here

thanks

6bytes not enough. Its bcm2 car. Itcould be as a6 c7 akl need bmc dump and elv dump

[rob h]

You could read the elv. J518
A bit of work getting it out.
You can load dump in avdi and get the 7 bytes.
There should be a dealer key option, or key to dump.
e8 transponders or org remote.



Try this dump:

[drugowaz]

So this is old type key or bcm2 key?

[z786]

I know elv has to be read. But I was being lazy mate. I've done a6 2008 and 6 bytes and pin did the trick

[drugowaz]

Its banana or smart key

[z786]

Normally flip key mate

2009 and up with 256kb module can not be done with 6 bytes only. Has to have EVL dump if you do not have key form delaer.
If you buy key form dealer, you can learn it with 6 bytes.

Also if EVL was replaced by Dealer in early models it will have module form 2009 and it will be same. Happen to me , had 2007 A6 and could not do it with out EVL dump.

Q7 till 2016 is same as old 2007 . 2016 and up is BCM2 cars.

Thanks buddy. I know the manual procedure just looking 4 short cut lol

[qeso705]

When car don't go to dealer anymore for keys just change immo data in ezs and gearbox for new one where you will know all 12byte and learn this key. With vvdi very easy, smok possible to without big problems but litter more dump playing.

There is no short cut for module after 2009 with 256kb file unless you buy key form dealer by VIN .

Its 10min job when you change immo data in elv. When you have 6byte from ecu which is 1min, obd2 1-16 together to ignition on and can direct on the left side of dashboard. Next change immo data in elv and gearbox when automatic and prepare new key and learn it.

Please tell me how you going to chnage data in EVL if you do not have access OBD ?

[qeso705]

With 6byte ecu cs+pin we have full access to elv. Communication with elv should be without ignition but in case when not just bridge 1 and 16 in obd2.

If you have smelecom tool...

then you are damn rich... $5400 @ Aliexpress

Hello, if i read ecu motor and have 1 key. Can I prepare a dealer key to learn it using vcds.?

With Tapatalk

[qeso705]

You can't. ECU contain only 6byte, you need 12 for preparation. VCDS don have possibility to calculate login on the way which need q7. You need more serious tools for starting keylearn procedure.

Better start digging for the elv!

[qeso705]

1)You can't scan for byte number 7 from megamos 8e. Trick with tango scan is that they know 11bytes and scan for byte number 12.
2)Get real tools and you will be able to do it when till 2009/2010 in 2min.

[drugowaz]

What is hood tool? Theft tool?

[qeso705]

What you mean?

[drugowaz]

Why is good tool by you that do akl from 09-14 a6 c6 q7
Read all cs needed add key

[qeso705]

You cant read all cs in 9s12dg256. You Can only change 6byte which you dont know for new but then any dealerkey want work anymore. For cs+pin read best option is smok uhds as it read edc17 only with direct access to Can. Change immo data with it possible too. only problem that you need after that manually put to anydump from elv new 12byte to prepare dealer key.

[drugowaz]

Change bytes where in elv or ecu?
How about all other modules CP protection?

I still do not understand how you going to write other 6 bytes to EVL.
On module with 256kb, made after 2009, You can not read /write EVL with 6 bytes only, No access , also VVDI2 not support writing of CS by OBD?????????????????

[qeso705]

Read and write not allowed but immo data change possible. Cp and cs are diffrent things. Vvdi should do it without problem as vvdi1 already have this option.

You are talking about immo data change , Adopt Module function , correct ?

[qeso705]

Yes. All the time.

Clear your pm :)

Hello a6 4f 2007 all key lost, i have key from other car but the key is locked and cant be unlocked without original ezs dump. Any chance to do it vice versa and add the key into ezs dump? I have FVDI2018 and xprog.

[drugowaz]

No..........

[TESTASTRETTA]

Can these immo data be changed by FVDI2018 or what tool i need to change ELV immo?

[PocketHero]

VVDI2, not the cheapest chinese clone

[TESTASTRETTA]

Ok thanks i plan to buy orig VVDI2 in near future if i will find enough potential customers in my region

[sdnatlst]

I have 2012 Q7 all keys lost,, what is best option to make keys for ir now a days,, VVDI 2 is enough?? can do it without removing the ELV ?? i dont mind to change immo data as this car will never go back to dealer for keys.

[drugowaz]

Only remove .

[sdnatlst]

Any guides on that?

[bauvaisis]

VVDI2 works great on these ELV and ID8E keys ;) . Best would be to read ELV EEPROM by OBD . Sometimes you do need a working key unfortunately . If it doesn't work, take out ELV, read MCU with XPROG or VVDI prog or other , and prepare dealer key with this dump then adapt key to car , finished ;)

thanks for the help, how easy is it to remove ELV on this model, any info or guides ?

[bauvaisis]

It's like on the Audi A6 or s6. Not the easiest job but can be done in 2-3 hours by going step by step
