HELLO Scotty , i wonna know smth.
My audi a6 usually shows the dpf is blocked (reason quality of diesel or smth else) , and i have found a solution , driving 20 min with 70 km 2500-3000 rpm ( italian tune up ) and then it goes away .
I want to know when its gone it means its clear 100% ? Or its clear only 10% or less , becouse im thinking to clean it to a specialist , ive heard from my friends dat car drives more smooth , fast and consume less fuel ?
What u recommend me to do clean to the specialist or italian tune up ?

Driving the fast does help but those are these are extremely complex cars and you need a pro Audi mechanic with a dealer scan tool to really make those things run correctly and check all systems they are not do-it-yourself repair cars and they're extremely expensive money pits as they age
