thanks for the posts got a couple of directions to follow-up now, first stop check earth wire and have coil driver at ecu checked, thanks staggers. if nothing shows itself snoopy your up next, by way of background while our mechanics and auto electricians are pretty good up here I wouldn't describe them as leading edge,( had car booked in auto electricians after being at mechanics seemed fine until I told him it was a Volvo, he started to tear-up and call out for his mommy not a great start)
If it alright with you snoopy I try to contact you when my mate gets back from Perth with my ecu's and follow-up with options with your Volvo tech's (i assume I use the message icon at bottom of your post)
really like my Volvo, but after all this think ill give it a name, maybe something classy like my mother in-laws name in Swedish
