I went down to Mississippi to purchase a 2004 Freightliner 144 super high roof for a song this week as a non-runner. Been sitting 3+ years, the guy bought it off his business for a swap project before figuring out how temperamental the MB diesels are. He tried to figure out the van itself before giving up.
The symptoms:
Cold start, immediate stall in 1 second. That's as far as he got.
Cold start with EGR and/or MAF unplugged, it will start and idle. Throttle works, but no power and excessive smoke due to lack of boost.
Warm, it can start with them plugged in... but no throttle response.
Had 60 codes in the Common Rail system alone, and another 30+ showing on the regular OBD generic system. Everything under the sun was listed, but I attribute a lot of that to low voltage... the battery was D-E-A-D from the constant start-stall until it wouldn't crank and then sitting a few more months after that.
I cleared all the systems and got it idling... Every now and then, the idle sound changes and there is throttle response, albeit in LHM (3k limit).
I finally got the CDI system to show a code (no MIL - yet), and its P2355.
I won't have any time to look at it again until at least Monday, but I am thinking to pick up an EGR gasket and see about cleaning the EGR valve. It looks new-ish, but you never know what 3+ years of sitting will do.
There is no turbo boost, either indicated on the scanner or feeling with a boost hose off. In fact, the scanner shows vacuum when off-idle.
Other issues of note: It was initially parked due to trans LHM (2-R lockout). CAN bus-faults listed are no comms with A94 (CDI control), P15 (instrument cluster), or A2 (ESP control unit). I am not sure if those are due to low voltage issues yet, or something else. Initial tests show the N2/N3 sensors are reading accurately, and the rear wheel sensors are reading accurately as well. The fronts, however, registered no changes with the vehicle stopped or in motion (one was negative rpm, the other low rpm, both constant values). Obviously I'll be checking and cleaning ALL the grounds Monday.
Anything else I should be looking at?
