Starting the engine of my Vauxhall mokka the E89 code appears. When I drive the car a few miles switch the engine off then restart it again the fault disappears. Is this an O2 sensor fault
Our answer:
Hi Bill,
You've not told us the model year or any engine details, but, looking at the error codes for the 2012-2015 1.7 diesel Mokka, we discovered that error P0089 means a performance problem caused by the fuel pressure regulator. It's best you bring the car to a good mechanic to have a look at it.
