Should I worry about an engine fault?
HI there, I drive a 2014 Opel Mokka and since Christmas every time I start engine CODE 89 comes up on the dash. I brought it to my local dealer and they didn't know the cause but say its something to do with emissions of engine. It's fine when car is warm and when you start engine again when car has been driven the code doesn't come up.
Regards Ian
Our answer:
Hi Ian,
It's completely unacceptable for there to be an engine error code on a 2014 car and the dealer not to sort it out. We recommend you bring it back to the Opel dealer you bought it from and insist it is rectified. That car is still under warranty after all.
