Hello, I have an Audi A5 2008 3.2 FSI QUATTRO Tiptronic with around 200 000 miles. I’ve just bought the car and I get around 13mpg (US) in the city. Mostly traffic, but in my opinion it is still horrible. I’m thinking about doing a carbon clean up, so I was wondering, what are you guys getting in mpg in the city? My urban is 33mpg. For the people that have done the carbon build up clean up, did your mpg improve? I’m also missing 3 out of 4 catalysts. No engine codes. Any info would be appreciated 🙏🏼
