Hi i have a 2001 s60 2.4t,whilst traveling slowly and turning to the left sounds like abs is coming on,if i switch the stc off it stops no lights show on dash,it also has the emission system service required light on,had it in volvo garage they said it was front lambda sensor so i replaced both front and rear,it still comes on,if i reset it it stays off for a couple of days,any help on these items would be great,thanks.
