2009 Freightliner Cascadia

http://www.demanddetroit.com/locations/default.aspx This is the link for all Detroit shops. Your zip code will find you the nearest authorized shop. Good luck!

 

If you ever get to Vancouver BC the guys at Cullen Diesel Power (Detroit/ Allison) are the best shop I've ever dealt with and their diagnostic skill is amazing. They never throw parts at the problem. They find the problem and then fix it.

 

with key on motor off flip over ride switch count # of blinks ck. back with list will try to help call 800 445 1980 DETROT

 

with engine running brakes set and wheeels chocked get your mechanic to climb under truck and try to wiggle engine harnesses to see if he can make motor cut out . my 2009 needed a harness it went to different shops 9 times until i lucked out and broke down near a shop that knew cascadia's well they change 6or7 harnesses a week. BTW there was a recall on window gaskets on windshield upgraded ones dont leak u will need to get computers under dash checked and fuse box for water damage

 

Same problem in my truck and it was DPF problem. Hope it help you.

 

The company I work for uses Valley Power Systems, specifically the Ontario shop:

They have a few locations around the So Cal area though.

Edit: Also to add, the windshields leaking is definitely a major problem, I just had to call out Safelite to reseal a windshield on one of our newer trucks. The design on these windshields was supposed to be "the next best thing", but instead they just leak constantly. We have had at least 3 or 4 trucks that have had wiring shorted out from water pouring through the windshield area.

 

Thanks to contributors to this thread. Very useful info.

 

Welcome to the DPF problem club. Had similar problem manual regen did not solve it, good I had warranty on engine. Freightliner fixed that. Since than working on auto mode.
