Hi All,

recently purchased an 2018 Audi S4 B9, the issue i have is the start stop is not working - the A is crossed out on the VC. I am not sure if the previous owner maybe coded this out Via VCDS/OBD11.

does anyone have any information on how to revert it back? I do have access to VCDS

thanks in advance

Might just be the cold weather. My S4 hasnt auto stopped for a couple of weeks now as only doing short journeys during lockdown.

Check the temperature in the back seat. It does cancel the stop/start if it is higher than the front. Just reduce the temperature if it doesn’t work before trying other alternatives

Or lower, also, for those only performing short journeys, may I recommend a smart charger as start stop batteries can get 'grumpy' if they're not exercised enough in the cold. I have one permanently connected to my car...
