anyone experienced the above or know what the cause is on an S3 or other.
Happens on cold starts only and lasts for maybe 2-3 seconds, and is maybe getting worse or I am noticing it more
Forum search referenced it as a “secondary air pump” whatever that is? But was not confirmed
S3 saloon as sig, 4 months old and just short of 4000 miles
