i think you should change sbc unit
pumpe work long and you have low pressure

Vheck with the dealer, many are under extended warranty coverage.

Pump working very well with a lot of pressure.
The only trouble is C235C and I want to escape it.

there should be a ten year warranty on your sbc system

get it changed as the back up system is not that good if it fails

i have seen dealers here change them with 300,000 miles on taxis free of charge you can do reset with diag but why when you can get new fitted free

There is no way to change unit at dealer.

On the other hand SBC unit working very well, the only problem Is dtc C235CnotC249F

Hi all,
I have same problem, but my DTC is C2359.
First I tried to clear it by "W211 SBC recovery by OBD" tool, but didn't help, because this tool can clear only the DTC C249F.
I checked this DTC's (C2359-C235F) in DAS simulation in developer mode
SBC_DTC_C2359.jpg
and I guess this DTC's mean that one of the pressure sensor is wrong.

But I will check it on the weekend.
If somebody has any new information or idea, please don't be shy to let me know! :-)
