Now replaced coil and shifting attention now to the high use of fuel and dodgey emissions from the car .
Have decided to replace the two lambda sensors in the hope that this will remedy the problem . Does anyone know how to reset the cars computer system once the sensors are in place.? Dont want to go to a volvo dealer and pay the £25-30 for them to flick a switch ....if i can do it myself .

 

you need to find a mate with a diagnostic unit.. the codes in the ecu need cancelling...... i don't know of any mecanical ways of resetting...

 

thanks v70 man - will need to find someone in my area that can do this then . incidentally is there any link available that you know of where i can get a definition of the icons that flash up as a result of the computer system monitoring process?

 

i have heard that taking the battery cable off for several hours (maybe even 24h) will do the "resetting". not sure though.
