I've got a 08 Partner B9 that's currently in limp home mode.
When read with diagbox the code comes up as P0234 Turbo Pressure Electrovalve Control - Permanent fault, flow too high. (Anti Pollution fault on the radio display). The fault is there at every start up, and if it's cleared it comes back pretty much the first time I push the engine to 60mph.
The EGR valve was cleaned when the anti pollution fault first flashed up (it showed intermittently), but this was pretty clean anyway. After reading the code I've so far checked the hose from the MAF to the turbo (changed the orange rubber seal onto the turbo as it was damaged). Otherwise I've only checked any accessible hoses from the top. Also read on here about a 'breather' pipe from the boost pressure regulation valve that sits near the injectors - cleaned the filter and checked the pipe was clear. From underneath I can't really see much to check pipes into and out of the valve for damage.
Along with this fault I have a leaking injector (no fault codes specific to this). This has been tightened down but it's difficult to check the leaks gone completely due to all the muck still there.
Could the injector be throwing up the P0234 fault code, if not does anyone have suggestions as to what to look for? Thanks in advance.
