Remember that Reading OPC are PCGB, or at least are owned by PCGB, so by going to Porsche UK, you are in fact, complaining to the same company.
I've never heard of no goodwill for a car that wasn't purchased from a OPC before, but can see their point. It's a tough market at the moment.
If it's a major fault (ie. over £1k), then I suspect PCGB/Reading will offer something anyway. It's a 56 reg, so can't have been long out of new car warranty?
Wrt to getting a reduction. You rarely get anything after the event, so best to negotiate this once you know what the problem is. The problem (as you say) is that you won't get your car back until it's paid for and cars stored at OPC for any length of time tend to come back a bit neglected, so make sure you've got recent photos of your bodywork.
