Hi,

Does anyone know of any problems with the cruise control system on A8s? Recently my cruise feature has failed to work. Is there any way of resetting the ECU? It's not adaptive cruise control, just standard.

I have tried disconnecting the main battery for a minute or so to see if the ECU resets itself, but to no avail. Have I inadvertently turned it off in the MMI menu or something!?

Any advice or guidance would be gratefully received!

If the engine ecu stores a power train fault the cruise deactivates automatically so for example a common issue is the brake light switch and clutch switch for manual versions however the A8 is auto with two types of gearbox multittronic and ZF.
