Have you checked behind the port to make sure it's all still connected alright?

 

[Scullies]

Check the fuse too

 

[GeoA3]

which fuse to check?

 

[GeoA3]

Have you checked behind the port to make sure it's all still connected alright?

yes

 

[Scullies]

I can't remember off hand but it might be #10, something along the lines of engine management.
Can you start the car?

 

[GeoA3]

yes the car starts fine all ok no problems,

 

[Lewis583]

As said fuse is the first place to check. Do you have an aftermarket radio fitted?

I'm on my phone so don't have access to fuse diagram but there definitely is one.

 

[GeoA3]

I still cant fix this problem!!!
I get this erros
the problem started alone I didn't touch any wire or something it was work perfect
yes I have aftermarket headunit but it did work smooth so its not the headunit
any ideas ? maybe change the ecu? the car starts and drive like normal

[@udi A3]

When you first install vcds you perform a device test, have you tried re installing

 

[GeoA3]

Yes when i press test i get this error " port status ok . Interface not found"

 

[@udi A3]

Hmm buy genuine

 

[GeoA3]

hmm is this a wire diagram for the obd port?

Try it on another VAG car !

 

[@udi A3]

I think your cheepo cable has failed on you try another cable or take it into a computer repair shop and see if they can check it out.

 

[GeoA3]

I tried to connect to other car seat Ibiza 2013 and its worked so the problem is with my car.

 

[@udi A3]
