I tried bba , but they don't supply volvo throttle bodys anymore.i cleaned the throttle pot, even though it wasn't that dirty and had volvo download some new software.The car has been driven everyday for over a week and it drove perfectly and better again the ets light stayed off.The volvo dealer was a small bit reluctant to do the download at the start but then agreed.The download is only a faction of the price of the throttle pot,so I would recommend trying it before purchasing the throttle pot. Thanks for all yer help.
