Update on Volvo.
I have looked at wiring etc, all looked good or so i thought, bonnet up and i went to the ignition to turn on and read some data, as i turned it on some white smoke started to appear from under the bonnet!!!! heart stops panic!!!! turned ignition off quickly ran to front and could see a red glow around oil filter/breather, pulled battery off smoke stopped,panic over, had a good look air filter assem out so could see better and on filter housing there is a heater for the breather could not belive it now waiting for £145+vat of parts then fit and see.
