I had the Engine Failure Error & 3 Beeps Etc, This appeared after going through Floods.
The overboost valve had never been relocated so assumed that.
Dried the overboost valve out & relocated, For a few days no error but then it came back & performance was intermittent.
Had the error codes read off the Ecu & P0235 Overboost was there.
Ordered a new overboost valve & fitted Last Mon.17th Dec.
Since then No error/3 Beeps but the Performance did feel flatter at times ( I just thought it was me !!)
Tonight coming home V Cold -1.5 Deg Start to overtake 4th gear & Engine Failure 3 Beeps, So it would seem the overboost valve is not at fault !.
I again checked for leaks Etc on Hoses but could not find any.
I unplugged the Egr valve & drove the car . No errors but the car did not have the usual surge of power when it is running Ok.
Re-plugged the Egr valve But this time blanked off the Egr so it was sealed off completely. Drove the car, Again not the usual surge of power but no Engine failure error or Beeps.
So i appear to be left with 2 items that would make performance inconsistent & cause overboost !!.
Faulty EGR Valve or Faulty Wastegate Actuator ??
Can i drive around with the Egr Blanked off for a few days to see if the error re-appears ? If it does this can only surely mean the wastegate actuator is at fault !!.
If it was the manifold Pressure Sensor that was faulty , This wouldn't make the power flat/inconsistent as it only Monitors pressure/warns, It does not bleed boost off Etc so the car would drive consistently below the warning threshold ??
Ideas / Input ??
