Hi Experts,

 

I have a 2005 skoda octavia 2.0FSI (petrol) which displayed the yellow/amber warning lamp. After a quick scan with my "ebay" scanníng tool it showed this error "P2203 NOx sensor circuit high bank1". There is no noticeable change in performance or idling and the only thing that has changed lately is that i have started to fuel it with only Shell V-power 98 petrol rather then any other garage 95 or 98. Could it be this? or is there more to it? 

 

I have also attached to pictures

 

Your advice would be priceless.

Erase the code and see if it comes back, it could just be a dodgy connection to the lambda probe.

Thanks for the quick reply, I erased it last night drove with it this morning no problem, but it lit up when driving after lunch again.
