I've bought a 2004 Doblo which can't go faster than 110km/h because the turbo is always on. Engine light flashes one second and the car goes in limp mode.
I've read a lot on this forum and it seems to be 'normal' that a 1.3JTD has this error. It can be a seized waste gate or the sensor.
I installed MultiEcuScan and I have driven on the highway with my laptop attached to the ECU. The boost sensor fluctuates between 1030mbar (idle) and 2911mbar (when accelerating at traffic lights). Light goes on at 2496mbar.
It looks perfectly normal to me (except everything above 2,5bar ofcourse) so does this mean that it cannot be the sensor and it must be a seaized wastegate?
Therefor I took off the hose from the turbo to the actuator and connected my compressor to it. The wastegate rod moves about 11mm when I apply 3 bar pressure.
So can I assume that the wastegate isn't seized either?
edit: it looks like it's getting better.. I am not hittin the 2.9 bar anymore after the compressor trick
edit2: I can go past the 3000rpm! Hopefully it stays like this! Is there any way to keep it working? Some additives or fluid?
