Audi issued a tech doc that says because of the tolerances of the turbo, sooting like this is normal and won’t cause any damage.

Did you find the cause of the soot, sounds like a similar problem I have at the minute

Hey just purchased a 2017 A6 Avant on Sunday and loved the drive home, but I’ve noticed some black soot to the left of the turbo just behind that looks to be coming from somewhere on the turbo, has anyone seen this before? Or is it normal? ive got it booked in at Audi on Saturday for a general look over anyway so I’m going to get them to check it out but I’m impatient and want to know if it’s something to worry about now Uploaded some pictures of what I mean Thanks Keal
