Hi I'm new to this site but have had a V70 for w few years. I have a 2001 V70 2.4 It has recently started giving me "Engine System Service Required" and "Urgent Engine Systems Service Required" messages. It is running like a dream but I have been told it could be the oxygen sensor, any advice as its a pig of a job to change.

My ODB is not picking up any codes (probably a bit old).

Many thanks

Mike

 

check or have someone check your alternator, autozone and advanced will usually do this for you for free
