| Post subject: | Buying a Cayenne 955 |
I'm thinking of buying a Cayenne 955 to use and as I won't be doing many miles per year, 1-2,000, I wondered what costs might be involved in that. Does anyone have experience of running a 955 or have one for sale? |

Sorry didn't see the original message otherwise I'd have responded. I had a V8 2005 for 3 years. I did around 30K in the time I had it. They need looking after and a lot get used as an appliance. Mine had full OPC history. Some stupid design buts inherited from the VW Toerag/Q7 they are cloned from. Propshaft centre couplings fail, easier fix these days, old fix by Porsche used to be new £700 propshaft, these days there is a £150 fix which takes an hour but an OPC won't do it. A major issue is there are drains in the bulkhead, which drain into the wheel arches. These block & the bulkhead eventually overflows into the car. If left this destroys the wiring & can write the car off. Note that the 957/958 have the same issue! Mine needed a thermostat, due to the stupid design it means stripping all the inlet manifold off, around 7 hours labour & £275 of gaskets & seals. I had the water pump done at the same time. My water pump pulley was cracked, the replacement lasted 300 miles and exploded on the A2 in the peeing rain. This left us stranded, OPC interest, NIL, Nadda! Not impressed. There is a set of plastic water pipes under the inlet manifold which fail, this is time based not miles. Replacement needs the inlet manifold lifted. See above. The new kit is aluminium & used to be a fortune (4 figures) Porsche have considerably reduced the cost now. They are sensitive to tyres and alignment. I ran mine on Vredestein Vorti's which were awesome & had it aligned by a Hunter specialist. Make sure all the electrics work, mine ended up with a fuel pump problem & after chucking over a £1000 at it I spoke to Ray Northway, he was convinced it was a wiring issue & it would be £££££'s to investigate. At that point I chopped it in with another car dealer. Technically they need servicing every 20K, mine had an oil & filter every year, filter genuine OPC & Comma Motorsport oil 15W/50. The latter to protect the bores as they do bore score which destroys the block. Changing an engine is 20 hours! Big group on FaceBook which is worth joining as the sceptics do megamiles, loads with 250-300K miles on there. |
