plasticbadger Posted September 5, 2016 Share Posted September 5, 2016 Hi all, I'm hoping for suggestions on a weird fault on Mrs PB's Disco V8. It's a late Series 2 with the 4.0L Thor V8 and auto box. There's two faults that don't happen at the same time, but may be inter-linked. Fault 1 is that a couple of times while driving the green 'M' and 'S' gearbox lights on the dash flash, along with the 'D' in the speedo and the red light on the gear stick. A warning 'bong' sounds. Turn it off and on and it's fine. It drives fine while the lights are on. Fault 2 is more common, it has happened regularly for the last week. About 2-4 miles from cold the truck will suddenly just die. The engine revs fall and the engine cuts out. No coughing or missing, just falls to stall. It then won't re-start for between 1 and 5 minutes, it just spins and doesn't fire. No lights appear (the engine management light is on ALL the time due to a dead secondary air pump). Once re-started the fault doesn't happen again, or at least not within the 10-20 mile runs we've been on. It's only happening from stone cold. I've checked some obvious things and the truck had a recent (300 miles ago) full engine service. I don't believe the gearbox oil has been changed and on these later trucks there's no way of checking it easily. Any helpful thoughts?
