The def pump and injector have nothing at all to do with regens. This truck has a burner for DPF heating, rather than using post injection. Think of it as a large, somewhat temperamental reddi-heater. They need regular maintenance. You often need dealer software to decipher that is wrong. A...

It's my opinion that the steering/suspension on these is not as sturdy as it should be. I've seen lots of problems with bushing wear, steering box wear, etc. The ride quality often sucks. The interiors are made of brittle plastics that are easy to damage when taken apart and reassembled...

The variable nozzle turbo controller is a servo on the bottom of the turbo. It moves a linkage that turns a plate and a bunch of vanes in the turbine housing of the turbo. If allowed to sit, you'll sometimes get some rust on the linkage. Spray the pivot points with nickel antiseize. Granted...

If it's going to be sitting, I'd lube up the vnt linkage with nickel antiseize. Sent from my XT1585 using EO Forums mobile app

I would not use any additives. Sent from my XT1585 using EO Forums mobile app

Def degrades very slowly when it's cold. If it's cold in the winter where you live, then I wouldn't do anything. Sent from my XT1585 using EO Forums mobile app

In the external fuse box, the MAIN 1 fuse sends power to the STARTER SW fuse in the cab. Also in the external fuse box is the STA/GLOW fuse which powers on of the start circuit relays. Sent from my XT1585 using EO Forums mobile app

Have the threads in the cam housing pulled out? If those pull out , everything goes haywire. Sent from my XT1585 using EO Forums mobile app

I would just follow the guidelines in the owner's manual, and I would not use any fuel additive that mentions removing water. Sent from my XT1585 using EO Forums mobile app

Do you know what P0088, P0087, P0182, P0335, and P0340 all have in common? They're all for sensors on the same branch of wiring harness. 335 and 340 are for crank and cam sensors. These rarely go bad. I've never replaced one. Same for fuel temp sensor, 182. Yes, they're shotgunning parts at...

One big problem with this engine is that it doesn't have replaceable cylinder liners. It's not easily rebuilt at the end of it's life. Recognize the point when it starts to go downhill and sell it while it still has some value. Sent from my XT1585 using EO Forums mobile app

So, 150-250k before it becomes a smoking crater. Hmm.

What the average mileage people are getting on MBE900's before giving up on them? I don't know if this has been answered in here..

Tires will not affect it. You are capable of rephasing the shaft if it's wrong, if you have the tools. Post a pic of the shaft separated by the slip yoke, let's see if it's correct. Sent from my XT1585 using EO Forums mobile app

Also make sure the driveshaft is in phase. I started a thread about it recently. If this is wrong, high rates of transmission bushing wear is possible, which can exacerbate speed sensor faults. Sent from my XT1585 using EO Forums mobile app

No idea. If you're successfully retrieving the burner event log, then you're successfully communicating with the burner control unit. One should be able to clear P2030, but there generic burner fault code the BCU sends to the ECU (P141F) will not clear if the DPR history isn't cleared first...

Jean pm'd me, and we talked about some options. Sent from my XT1585 using EO Forums mobile app

You need an actual diagnosis. There are myriad problems with these transmissions, but often it's simple sensor or wiring problems that are relatively easily fixed. Loss of speedo suggests possible output shaft speed sensor failure, or wiring faults. You need an actual diagnosis. Sent...
