Motor control system failure code
Well had my 156 1.9 jtd 16v for just over 2 weeks, on the drive back it sprung the dreaded error but i disconnected the battery and that cleared the code and all seemed well until today when it appeared again. Thought I'd investigate it and had a old vag-com lead that i used on a old Audi and it worked a treat , the code was;
P0238 Manifold Pressure/Boost Sensor G31:Signal Too High
I'm guessing it's a overboost which was suggested when it happened the first time. Could it be a sticky vane/actuator or sensor?
