OK so a deal more checking required then of pipes and gubbings.
This car does have full history with it but got it at reasonable money as the EAS pump is running every couple of seconds. Headlamp wipers just blow the 10amp fuse constantly. Heated windows front and rear not working, occasional HEVAC test book coming on every now and then. Fuse box has that smell, the lovely aroma of shorting burning electrics.
I think a lot of the problems might be electrical gremlins. Since it has been cold (below 0 degrees) the EAS pump has stopped cutting in as much, so I am thinking air leak/hole frozen working like a bath plug. HEVAC test book not coming on, so thinking moisture frozen at earthing point now giving good earth?
I already miss my oh so simple 300tdi Disco.
