p1235 is a boost pressure control solenoid error. It will either require a new solenoid or could have a split vacuum hose to it.
I've made progress...
Immobiliser issue is now resloved after a clean of the Inj. relay.
P1238 is fixed after a clean of the EGR.
Only problem remaining is the P1235 error....
Failed Component Code: Positive boost pressure governor deviation
Fault Symptom: Positive governor deviation above limit
Warning Lamp Status: Warning Lamp Illuminated
Fault Code Storage State: Error Present at time of request
Event Count: 40 count
Environmental Condition One: Engine Speed: 3058.9 rpm
Environmental Condition Two: Fuel Quantity: 46.43 mm3/str
Environmental Condition Three: Accelerator Pedal: 51.37 %
Environmental Condition Four: Rail Pressure: 1309.78 Bar
Environmental Condition Five: Turbo Pressure: 1529.45 mBar
Environmental Condition Six: Engine Temperature: 92.29 °C
This only errors when accelerating hard. Prior to that car appears fine. Where and how do I check for a split vacuum hose ?
