My Disco 300Tdi (1995/6) has just started making a noise like something
dully tapping something else each time it rotates.
It happens whenever the engine is running and the clutch is engaged, in
neutral, first, second and third gears - but NOT in fourth or top, nor when
the clutch is pressed. It increases in speed along with engine speed.
I'm presuming it's gearbox, not clutch, because of the way it seems to go
away in fourth and fifth. Is that likely? Is there some part of the gearbox
used up to but not including those top gears?
It happens in low ratio too, by the way.
Hmm. Expensive repairs aren't really what I want having had several lately.
At 220,000 miles, it's not the easiest decision to justify.
