Fault code P0234 Megane 3

Postby SimonAshley » Fri Jan 13, 2017 11:39 am

Help .. engine warning light and service light have come on with messages Check anti pollution and check injection. Car runs fine though, no loss of power etc. Plugged it into a cheap OBD code reader and got code P0234 Turbocharger/Supercharger Overboost condition. Any ideas where I should start? It's a megane 3 2010 1.5dci coupe with 118k. Fully serviced. Any help appreciated. Thanks

I would start with the boost pressure sensor
