I had the engine light on my 2009 blue eff e220cdi. The fault codes are P0471 (powertrain control module has detected that there is a voltage reading from the exhaust system back pressure sensor circuit)
and P2626 (O2 sensor in the exhaust)
From reading this forum I am led to believe it is the exhast pressure sensor. Would this be correct and worth the £30 gamble in changing it. Thanks.
