AUDI A3 2005 need CS and pin

[super jumbe]

EEPROM 93C86 thanks in advance.

[super jumbe]

Got the pin from ECU and got CS but not managed to get the 7th bite, I know AVDI can read CS and Pin by OBD, any one got advice the next step to programme all keys lost on the table thanks.

China abriites also can get last byte from key. Not everytime from first try but work.

[super jumbe]

I tried FVDI not worked for me, I read some were I need to buy from Smok VW0010 A3 93c86 CAN OBD, can not see other option.

Do you have Autel & the APB112 emulator? You can use this to sniff the 7th byte without a working key.

[super jumbe]

No Autel pal, I wonder what the locksmith used before Autel/smok came out?

[the_big_d]

Zed full has a sniffer that can also do it but never personally tried it. Used Autel a few times though & every time found the 7th byte within 30 seconds.

You can manually try 7th byte with Tango, using cluster on the bench. You'll need Tango, a diagnostic tool capable of watching the immo status of the cluster for 'floating code OK'(terminology used from SuperVAG, others may use a different naming scheme for the live data), and a coil to attach to the cluster. Keep trying bytes with the Tango Search Comp Sec function until you get the floating code OK data out of the dashboard. You will need to put the cluster back in the car for key learning.

Do you know even smart pro has no option to read immodataon Audi A3 2005, but as Manta say FVDI you got to know how to use it, any one can give instruction or video how to read immodata with FVDI will realy appreciate thanks.

Yep a lot of these old Audi platforms were abandoned in favour of working on new stuff. Every tool supplier is guilty of chasing the new cars instead of fixing old ones at times.

No tool can read A3 2008-2012 dash.
But I've found once a 2005 was also blocked expect like this.

'Super Jumbe' is a mean bugger and won't invest in tools. My advice is past job on the guy who has :)

[super jumbe]

Why would I invest on old cars when I have started my locksmith after 2010, I am investing only on new cars full stop, back to Audi A3 I managed to get 7th bite and programmed 2 keys car started everything looks good only one issue, on cluster it says (SAFE) car was bought from auction is there a way to solve safe mode?

[evgeny87]

"car started" and "cluster say SAFE" is possible only with immo off.

[super jumbe]

Pal immo off will triger indicators and alarm on, not safe.
