How do you reset emission warning light on 2000 Volvo v70?

Answer 1

Try This. It worked for me.

with the ignition switched on

press the read button on the end of the stalk then press fog light switch twice this will put you in "in vehicle" diagnostics mode

in the messages pane scroll though all the checks by pressing the read button til you get to the end

hey presto warning light out

The 2000 year model does not have a read button on the end of the stalk. That was not brought into production until the 2001 V70
