2006 freightliner columbia with a mercedes motor om-460

can anyone help me diagnose this problem with my 2007 Columbia with a mbe 4000 when running on flat ground the truck will run good 75 plus Mi hr but wen it his a hill or mountain it will derate itself and loose power even bobtail freightliner cant figure the problem they replaced the boost sensor which was bad and checked the egr valve and turbo all checked out ok

 

My old one would slow down going up a decent size hill empty, so I feel your pain.
Best bet is to put it on a dyno at a Detroit shop. I can HIGHLY recommend Insterstate Diesel in Altoona,Ia. Jack there know his stuff. He works the 4pm to midnight shift.

S60's, N14's and 3406's fell victim to astringent EPA regulations that exceeded the engineering capabilities of the diesel combustion engine, not because they were "cheap". In fact, they were all champs. How you think you could possibly compare an MBE 460 to any of those motors just because your in Europe is laughable, at best. Perhaps your unaware that these motors are made in Sao Paulo, Brassilia not Germany. The principal, perhaps, that Volvo Trucks NA and Volvo Trucks EU are not the same animal by any degree, should be observed. The MBE 460 we a fleet welcomed, fuel sipping, budget economy engine that could barely climb a hill. At 1550f/t you need a good run with all 460HP to hold the hill. It is better than the 2,000's model 360HP Mack trucks. That was its appeal. That's all there is to say about that.

 

Sounds like injector failure

 

If you get a sec can you email that info.? For some reason those links are not coming up.

thanks

 

Doubt he will as that member has not been online since 2015.

 

I have one of these freight liners with the Mercedes Benz engines and had the injectors changed, just changed the ECM and the truck will still just start backfiring at unsung like the lifters tapping very loud, etc. if you #### off the engine for a bit around thirty minutes and start it back up everything is fine. Can anyone give me any advice on what the issue is or what I should do next I’m trying to get grained hauled to the elevator and need this truck very bad

 

Hi there I am tryouts by to find out some kind nfirmatin for a backfiring problem I am having and the abscess mjectors and ECM has been changed. When it starts backfiring you shut off the ENGINEERlrUG me and let it set for 30 minutes or so and it runs great again. I would appreciate any help anyone can offer. My email isrobertdupont2018@outlook.com thanks so much in advance

 

I have a 460 MBZ 2005, I have a Diag, SID064 fail 08 fault 01, I like to know what this means, if someone knows could help me out; thanks.
