[vwpolo]

ive had an engine light come on twince now and had it read to be bank i under freshhold , on my 1.6 petrol caddy and read some forum post stating that changing the o2 sensor may or may not fix this any help or ideas ? im thinking maybe a cat change or full exhaust would this maybe fix or will sensor need changing. no air leaks around manifold which somebody told me to check

Get it scanned. It could be any number of things. Scanning the ECU will point you in the right direction of the problem.

I've had the engine light come on twice now and (had it read to be bank i under freshhold)??????, on my 1.6 petrol caddy.

I have read forum posts stating that changing the o2 sensor may or may not fix this. Any help or ideas? I'm thinking maybe a cat change or full exhaust change would maybe fix this or will the O2 sensor still need changing.

Have found no air leaks around the manifold which I had been told check
