hey guys,

does anyone happen to have any idea what the part number for a bosch replacement o2 sensor is?(I have a 2001 2.0L S60 T), it seems its a bit hard to get hold of one of these things over here in sunny england.

also does anyone have any information about replacing these things?, Ive been to my local Volvo garage a number of times recently about my check engine light, paid them lots of money to change accelerator sensor, throttle body, and ECM, and dont really want to go back to them, they dont seem to know what they are doing :/ , the car was ok for a few weeks but now when I warm start it throws another check engine light at me again, Im guessing from what I have picked up on here that it might be the o2 sensors, if anyone has any ideas, they would be most appreciated

Cheers
Dave
