A new pump can be very expensive but if you can trust a secondhand one it is worthwhile. The noises from the pump sounded like groaning sounds. This noise is worst when sitting in traffic in hot weather. When driving hard I couldn't hear anything. I did notice a lack of turbo boost when accelerating hard through the gears i.e. lots of boost for a few seconds then only half boost in the higher gears. With a new pump the boost holds on far longer and on through the higher gears. If you have noticed the same problems it is likely the pump is on the way out. I asked my SAABtech if it could be cleaned/repaired, he didn't think it was worthwhile. I tried to rebuild one my central looking motors and it failed again no more than a week later. Its just not worth the hassle. NJH. -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
