Audi Q7 EZS Key problem

[Mario3]

Hello Guys

I would really need some help with my problem here.

As the title says, car is a audi Q7 and problem is it wont accept the key. I dont know what happened to the car it just came to me like this. Number of keys stored in ezs is 0 !! so i thought all i have to do is learn it back, i got Pin, CS from ECU, but when i go to learn key (with FVDI or immoplus13.) it cant pass the security login. I searched all over the net and found a post where it says that the doesent work with flyfvdi, so what can i do here exept ori avdi license or maybe vvdi ?

I read the ezs with a programmer. The flash when i compared to another that i found has some info from the beginning 000-1F0 unlike the other one who has all FFFF in the same area, the rest is 100% identical. Can someone please confirm if this is normal

And regards the eeprom, pin, cs is the same as in ecu, but i found a key in the dump but when i connected it on the car key number was 0

So is it posible to enable that key in the dump ? and check ezs-ecu compability.

PS: Im not so experienced with this type of immo system so any help is appreciated

Here is what i got from this:

ezs hw: 4F0 905 852 B
sw: 4F0 910 852

Pin: 9916
CS: 54 67 E0 8C A8 CF
KEY ID: B6AF1208

Thanks

Any faults in the module? These fail quite often, especially on early Q7 models. Typically there is a 00288 fault for steering lock actuator. Do you have the software and hardware # from the steering lock box?

only managed to find out the m.a.c add.ress

The sw and hw numbers are in the notepad file in the rar that i uploaded and i wrote them in my post above. No i think there was no such fault. Problem is that the car is 50km teared apart...

With fvdi and immoplus sw i can get them to enter service mode and dash turns off for a few seconds then i get again could not pass login... with avdi sw nothing happens at all

Hmmm.... what i would do is get a second hand ezs + key + elv and just virginize engine ecu.
Second choice is to fiind software for EZS but i dont know what is inside of ELV if it is possible to virginise

I will do that if the repair solution wont work, but isnt the ezs and elv on this car the same unit ??

I thought of doing that but i would have to change the CS bytes of all units in the car... Its not a big deal but i have only fvdi for this and didn do it before so i dont know if it will work

Is the same, in ezs is also pc stored just for info

Hello.
Dear,the problem in your EZS eeprom dump,try unlock your remote by original ezs dump,& after found any eeprom with same info,and learn the remote to this dump,and after writer this dump to ezs by xprog-m,after you can adapt ezs to ecu or ecu to ezs by obd2 via avdi,no need write ezs flash cause your transmission control unite (09D 927 750 FS) under passenger seat,not require to any other operation mean (12 cs) to write in ezs.

Difficult to say where the problem is since you have a differnet situation. Try to read flash and eeprom from ezs and post here.
