[Waterloo]

DOC looks good with a light dusting of soot on the inlet. Outlet of doser looks good and free of any oil tracking. Makes me think I will be back to the previous truck sooner than later.

Not so funny story. The mechanic got called for this DPF full light. He forced a regen with the dash switch then went back to diagnose a trailer light problem and asked the driver to get in the cab and operate the light switch. The first thing he does is canceled the regen!!!! The mechanic restarts the regen 3 times before realizing that the driver is stopping the regen!! Come to find out he does this all of the time because the engine is to loud to use his cell phone. Can I disable this feature?
