I have a lml with 23,000 miles. It's drank a half a tank of def fluid in 1,000 miles so I took it to the dealership. They ran a soot test on it and said it had 44 grams of spot build up where it was not being burnt out. They also hook a tech 2 up to it and said that they could find no issues. Any one else had this issue?

indirect injector is bad. pull the pass side fender well out and in the down pipe towards the bottom there is a mini injector that is connected to a small fuel line on the pass side rail. Its supposed to operate at 50-60psi. they get messed up all the time and leak. If you pull the injector out, tap it against the pipe and i think you'll find that some fuel drips out :thumb:
Basically the injector is leaky and when if you try to do a force regen to clean the soot mass, it leaks bad enough to keep it clogged up. I worked for GM and its a pretty common thing
