i have had this fault code
DTC P-code Description
16518 P0134 O2 Sensor Cir.,Bank 1-Sensor 1 No Activity Detected
So from the little i know, bank 1 is drivers side and sensor 1 is before cat.
the question is would this faulty O2 cause a strong petrol smell from the car, not under the bonnet just from the back and can some times be smelt in the car, droping from 150 miles from a £20 worth of fuel to barely 100 miles, and sometimes lack of power when accelerating?
A friend has a V5 2.3 mark 4 golf and gets 250 miles off £25 worth of fuel. i would barely get 150 from that now.
so is this F**KING sensor the cause of my problems? as i dont see it could be anything else as it has had an MOT and full service a month ago.
HELP!!!!
