i have been dealing with my sprinter cutting off under heavy load for years now. After replacing some injectors and still having the problem i learned to drive in a way where it rarely happened. Last summer it started happening more frequently. it got to the point where if i stomped on it i could kill it every time. another injector replacement, & new fuel lines, fixed the problem for about 2 months and it was back. this was while i was living in PA with no emissions tests.
Now im in colorado and my van will not pass the test on the dyno because it throws a CEL mid test. all the emissions are well within spec. they could also make it die on the dyno by stomping on it. I took it to als autohaus, who has sprinter customers, and it was there over a month where they could not figure out how to prevent it dying under heavy load. I didnt have time to start poking around with it myself at that time other than giving it a scan with my autel which showed a fuel pressure exceeded code (dont have the exact code, as i erased it and do not have my photos from that time)
at the mechanic
2 injectors were replaced 1 & 5
the fuel pressure solenoid at the back of the rail
fuel filter
van still dying
high pressure fuel pump was replaced and now it does not die when you stomp on it, but it failed the test today on the dyno. CEL thrown mid test again.
i cannot replicate this CEL on the road. i can gun it and the van accelerates and does not throw a code. i see no fuel leaks and there are no air bubbles in the lines
a scan today showed these codes.
CR Fault 3
N3FFF unknown fault
P2203-32 external quantity control by ASR
P0500-1 Vehicle Speed Signal can data invalid
ABS Fault 2
C1104 wheel speed sensor
C1105 wheel speed sensor
EGS Fault 2
and when i try to read these codes it shows none
last time on the dyno the codes thrown were wheel speed and the fuel pressure exceeded.
