+1 The value of a forum isn't just the narrow question and answer for the guy with a problem. It's a community for all and over the years with the use of the search engine, it should be possible to find previously contributed answers from a growing fund of Volvo knowledge. To make sure the answers are applicable it is vital that questioners return to the thread to post the outcome. Anything less is just selfish!
Also, while I'm ranting. A signature with the appropriate car spec would be a polite way to help others know what car was being discussed without having to trawl through the earlier part of the thread which might be pages long.
There, rant over.
