Tried tubigrip and ibuprufen, but it looks like Brufen 600's were the answer. Well I've bid on the binnacle I found with 65000'ish miles (its a KMH speedo) and looks to be in really good nick. The seller has confirmed it's all in working order. If I win this one I will get it fitted and pull the old one apart to work out how to replace LED. Did read something on one of the VW forums about how to do it but seeing and doing is easier than reading.
