'Cos I was talking about it ((here), the supply pipe to the rear off side unit has gone - it's rusted through where there's a clip on the subframe just before it gets to the cylinder 
. The pipe to cylinder joint looks interesting to say the least, so it might be time to twist after all! Other end goes into the antisink valve somewhere. Ah joy.... 
Pipe didn't turn and promptly sheared off, letting me know that the pressure in the rear suspension was not fully released..... The other end on the AS valve came out easy with the pipe spanner. There's a place in Edinburgh that can make pipes up, so off to get one tomorrow, and get it back on. Pipe fitted and we're back in service till the next one goes. Foolishy tried to check the tyre pressure in the spare, but unscrewing the valve cap just resulted in the entire centre of the valve coming out The tyre is dated wk 42 2000 though, so must have been one originally supplied with the car - I think I took it off the back after it had run at least 100k miles! Got one of my old winter tyres out of the garage which will do as an emergency spare - last time I had these on, the handling was awful, but then I realised they were made in 1986 or something, so maybe that is not surprising!!
