Hello everyone, I have a fabia 06 plate 1.2 htp and over the last few months the orange engine symbol comes on intermittently (on for a few days then off for a few days). The fault code states "bank 1 too rich". A local garage have looked at it several times and they can't find a problem so just clear the fault. I took it to a skoda dealer who diagnosed it was a servo pipe which was replaced. The light came on a week later so back to skoda who said it was a cam sensor and replaced, week later light back on! Took to another garage who said it was likely to be the oxygen sensors, has new ones fitted. Yes you guessed it - a week later the light is back on. Can anyone help shed some light on what else it could be so I am not bled dry of money?

Many thanks

Ps I have read all the other links too.

I would try the coolant temperature sensor next, it's cheap and they are known to give problems.

Thank you sepulchrave, I thought it might be an exhaust problems.
