Ran with the exhaust brake on auto the last few days. Exhaust brake definitely kicking in but as someone stated, have to be above a specific speed or rpm. If leaving it on auto helps keep the turbo vanes clear of soot, then I'm all for auto. I'm not much of a mechanic, especially on diesels so I will listen to the "experts.". LOL

I run mine on just about all the time. Reading the owners manual, the auto mode was to be used in conjunction with the cruise control. I used the auto mode when coming down from Eisenhauer Tunnel into Silverthorn. Set the cruise at 55mph and double tapped the exhaust brake to auto. Never touched the brakes. Same coming down Vail Pass. It is sweet!
