Mercedes sprinter 311 power loss

[Thomask]

Hello I'm new to this group, I need help with the problems with my sprinter 311 I've had it scanned and came up with loads of issues. The codes and issues are as followed

2244 no can message from control unit a1
2013 check component b14 can signal faulty
2510 check component y77/1 (boost pressure regulator) positioner signal faulty
2511 check component y17/9 (left egr positioner) positioner signal faulty
2067 b2/5 duty cycle signal faulty
2089 check exhaust back pressure (signal voltage too high)
2079 check component b28/8 (pressure differential sensor)
1436 check component b19/9 (temp sensor upstream of dpf) signal voltage too high
9186 canbus- can signal speed from control unit k1 is faulty
919e canbus can signal km reading
919d canbus can signal date from control unit ez8 is faulty
472d canbus message of component A1 implausible
7256 no canbus message from component n80 (scm mrm control unit)
4367 plausibility error between values of stop lamp switch and pressure sensor.
The van has not shown any warning lights on the dash I need to know which ones I need to fix first to get the vans power back as its in limp mode and for the rest to be done at a later date, thanks tom

Did you clear the codes and take a diagnostic read again? Could it be possible some of these could be old codes or you have a lot of issues. I would have thought you should have a EML light on. Is it working i.e. can you see EML illuminated at ignition on just before start? If codes all come back after clearing I would be thinking SAM or electrical issue. Low or bad battery might be an issue as well with some codes. Somebody else on the forum might be more familiar with an array of fault codes like this showing up.

The EML light comes on when ignition is on and goes off when I turn the engine on and I've not scanned it since the first one but will be getting done soon thanks

The CAN faults are usually from a low/dead battery so ignore those for now. It looks like you have DPF issues at some point.

Also that last one with the stop lamp switch can put you straight into limp mode.

Stumo called it better than I could Thomask. At least your EML is working as cowboys have been known to disable it to hide things, Get the battery changed or charged at least and then get the codes cleared and re-read again to see what codes comes up again.
