V6 experts please help 
Just got another fault code off my sick C240, in my Autodata book it says:-
P0135 Heated Oxygen Sensor (HO2S) 1, Bank 1, Heater control malfunction
It seems that the C240 has 4 Oxygen Sensors, I believe bank 1 is the right bank?.....is Sensor 1 the front one nearest the engine or the back one?
Thank you
