Audi recommends adding this to a full tank of gas (two tank fulls) for injector cleaner:

amazon.com Volkswagen-Fuel-Additive dp B00PV72MQ2 (you have to reassemble the link by adding the / back in for each space)

I have used it effectively to remove carbon from the injectors that were causing cold start misfires. (There is an Audi TSB for this treatment.) According to my local independent Audi repair shop, this is different that the typical Techron type cleaner. He says it outperforms anything else he has tried.

BTW, the retail price is $19 US not $29 that Amazon is selling it for.
