Does my Mokka have an O2 sensor issue?
I have code 89 on the dash, amber and tool. Vauxhall Mokka 15 plate Is it the o2 sensor?
Our answer:
Hi Carmen,
That could be one of the reasons for the errors, but there's no way to know for certain until you get the car plugged into a diagnostic computer at a garage.
