do I need to go to volvo, whats the best way of checking it?

Volvo are not likely to much help for you.

As you are not complaining about the way it drives I doubt there is a need to replace it. Just give it all a good clean to make sure it is not sticking. Oil deposits will have it stick and hard to move.

Before you strip down the distributor can I suggest you try the following: buy a bottle of injector cleaner, disconnect the distributor feed gas tube from the filter - there will be a small escape of gas, do not smoke when doing this, probably best done with a cold engine. Pour half the can of injector cleaner into the tube, then reconnect. Start the engine on petrol, switch to gas and stop the engine as it splutters with the injector cleaner going into it. Leave to soak for an hour or so or even overnight, restart the engine on petrol then switch to gas - it may stall and you may have to repeat this a couple of times until all the cleaner has cleared and the flow of gas been re-established. I have just followed this procedure on my S80 factory bifuel with astonishing and pleasing results - it runs more smoothly now than it has since I bought it in Feb. Without the time and aggro of removing the distributor.

I think this procedure both cleans and lubricates the unit from the inside.
