Driver Complaint – Intermittent poor performance and engine management warning light illuminated with fault code P1125 in the system memory.
Cause/Symptom – Incorrect calibration of the engine ECU causing detection of a turbo overboost condition/wastegate concern.
Rectification Route – In this instance there were no issues with the system, a software update to the engine ECU was carried out by the Vauxhall Dealer and the fault and the code was removed from the system.
