Just signed up to see what I can learn. Proud owner of a somewhat restrained 2012 A7. I have no manual so i’m hoping to find some help on a few issues.

OK so simple stuff first…

I have a button with an uppercase A in bc a circle which I assume turns off the auto stop feature - but the engine never stops at traffic lights etc. Should the light on the button be on or off to enable that feature?

Then the more complex…

 

Thanks Jason. I will experiment again.

So having the button orange light either on or off doesn’t seem to engage the stop start feature - so I imagine it might be disabled on the console.

Current status is Stop start does not operate. I am used to having a working stop start on other vehicles so would ordinarily want it to work. I do hear people recommending it should be disabled to prolong engine life. The A7 has done 92k so maybe leaving it off is the right thing. Saving CO2 emissions is however also the right thing. Another consideration is that technically I have a three month dealer warranty and I would like to get anything that needs attention sorted out before that expires. Eg the convenience module in the other post.

Hi Chris  Re: Convenience System Control Module  CSCM

1: I have watched the video .  Thanks for posting , it was interesting . * However the cause of the problem was overlooked in the Fact he failed to notice the link ...at 12.4 on this video , when he does not notice the Fact he had a code which is consistent with a negative earth short which would impact on a base transistor in the module . The point is the fix he did will be a temporary  fix as, He failed to find what was causing the short in the circuit and so that fault is still there .  The fact he did not refer to the CAS system Car Access System in name was a bit suss 

2: It is not unusual for people to code this facility out , ie disable this feature for security reasons .Jasonj

 

 

That is a fair point and well spotted. Is there  a particular diagnostic tool I should but to gather these codes? My local audi dealer gave me a free dongle to connect the My Audi app but it doesn’t provide much information.

I should say that I am also seeing a fault on spoiler system - which I understand is controlled by a module in the boot - is this also the convenience module?

Brilliant! Thanks I’ll try that.

Will the Audi dongle the dealership gave me work with any of the scanning applications?

Found these instructions
