At this point I didn't know there were two fuel pumps, but on finding there was another on RH side I checked and that pump is absolutely bone dry.

Hope this helps.

You should only have one pump (on drivers side), but 2 float sender units, these are connected inside the tank. The pump scavenges the passenger side of the tank and pumps from the drivers side.

If the passenger side of the tank is full and the drivers side empty, you either have a fault on the transfer pipe work (pipe popped off or kinked) or the pump is knackered. The high pressure pump on the engine can often suck the fuel through if there isn't too much engine load.

That assumes I'm taking about a D5, if it's the VAG 2.5D I don't know if they use the same pump method.

Thanks again for info. However this is a petrol car.

I'm fairly sure it's the same pump layout as D5.
