I recently discovered a quirk in our Disco which won’t start unless the brake pedal is pressed down.
If I sit in the car with the engine off and press the brake pedal a few times I can easily completely exhaust the servo vacuum. When I then try to start the car, it won’t start unless I apply extreme pressure to the brake pedal. Once I had done it once, I twigged on quite quickly but it was a little confusing the first time it happened.
Simple stuff really.
