What are the exact symptoms and behavior of the issue you're seeing? I do know of a fix that was pushed out in Germany, but will refrain from commenting further until you can please share details and if I feel it's applicable I can comment on further.

Hi


Basically the fault is the Active Cruise will not turn on, you just get the error message up on the dash I have uploaded a picture of the dash board message

In Germany apparently there is an update to this, so I would double check with your dealer.

The update is 90L1 apparently any idea how I find if the one in Germany is for this?
Below is the email I received today they don't think there is an update

Thank you for your recent email to Andrew Doyle, Director of Audi UK. As a member of his Executive Office, Andrew has asked me to investigate your concerns and contact you directly.

I was naturally concerned to learn of the difficulties you have experienced with the adaptive cruise control on your vehicle. I appreciate that expectations of reliability and build quality are high when customers purchase an Audi and that any failure is therefore disappointing. Whilst we take pride in producing our vehicles, like any vehicle manufacturer, we cannot guarantee that the many components which go into the complex build of an Audi will never fail.

Having spoken to our Audi UK Technical Team they have confirmed that the Factory are currently looking into a software update to rectify the issue with the adaptive cruise control. We are unable to offer any time-scales regarding this at the moment and I sincerely apologise for any inconvenience caused.

I have spoken to Claire Hughes, Assistant Service Advisor at Shrewsbury Audi who will be checking the information related to the future field campaign and update for your vehicle, Claire will contact you as soon as there is any further information.

Thank you for taking the time to contact us and I hope the above will prove helpful to you. In the meantime, if I can be of help with anything else, please contact me on the details below.


Kind Regards
