Hi could anyone explain how to force a regen on the egr? I keep reading it's possible on ccwa engine but can't find how to do it. I have insufficient flow so light is always on and want to try it before spending out on egr or cooler. Thanks
Noticed today that my mpg is very good not normal lol. I checked my dpf and it's at 22g with 1.6 ash what's a normal ? Has any one tried a terror clean ?
There is a post a3/s3 8p section on terra clean
