I think eBay is your best bet, especially for international sellers.

So I took a big gamble and pick a s5 on a 08 up unseen only in a video and photos very cheap, running really rough and smoking, so took a wk off work and iv done a full carbon clean and it needed it, new vvts, new valley pan gaskets, rocker cover gaskets, plugs, pcv valve, a head gasket test came back blue thank god not changed green or yellow, new air filter started the car up lovely running like a peach, so jobs too do oil filter new oil, put a new crash sensor in the passenger door as the lights on, new headlight stork as its not staying on,new bonnet lift as having to use a bit of wood to keep the bonnet up but waiting on these to turn up so so far so good

Check your oil pump

Hello Chris, I notice your mechanic friend is now suggesting that this needs connecting to an oil pressure gauge to actually measure the pressure. To me, this would have been the first port of call, since sensors and associated wiring can give spurious warnings even when the pressure is correct. As you probably know, true oil pressure should only be checked after a run of about 10 miles - when the oil is up to operating temperature. Some, incorrectly assume, that when the coolant is up to temperature, the true operating oil pressure will be achieved. Wherever possible, a car should be test driven over 10 miles to check is if oil pressure light does flick on on idle. I am unsure whether your sitting on the drive testing is after such a run, and if so, it might point to a connection problem where car movement influences the connection. Anyway, an oil pressure test it needs. Kind regards, Gareth.
