My TDCI is making a grinding noise when driving in any gear, normally above 20MPH. Only happens when accelerating or holding speed and stops as soon as the clutch is dipped. It's more noticeable when the car is slowing down or accelerating and it sounds like a grinding/raspy noise which matches the engine speed is getting louder the longer I'm leaving it without repair. It's had a new clutch/DMF about seven months ago so I'm thinking it's the gearbox? Noticed today that when it's stood idling it's making a very faint rattly noise which stops when the clutch is pressed. Any ideas what it could be and/or if it's likely to be the box?

was it making noises before the clutch/dmf change? did you also replace the clutch slave cylinder?

Yeah slave cylinder was changed and it was makin that much of a noise before the DMF was changed im not sure tbh. Its got progressively worse since like and now getting very loud, but a different noise to what the dmf was giving if that makes sense

It could be a bearing in the gearbox. If you idling, and leave it in neutral, does it make the noise? Does the noise only go away when you put the clutch in, or does taking it out of gear also get rid of the noise?

Yeah, there's a faint noise at idle which stops when clutch is in. The noise isn't really noticeable tbh until your accelerating or letting the car slow down in gear, that's when it's at it's loudest and it stops as soon as you dip clutch.. revving it in gear but clutch it doesn't replicate noise either. How much would a recon box be for the 1.8 TDCI's, roughly?

I've spoken with a gearbox specialist in Halifax this afternoon who seems to think that it will be the Input Shaft Bearing which will be £20-£30? Apparently the MTX-75 is fairly bulletproof and doesn't tend to have any issues?

the gearboxes on any of the fords dont have many issues to be honest

Ford do tend to make decent gearboxes, it must be said. Even the old Ford Fusion we had a few years ago, which we all decided was a heap of scrap, my dad said that it had a gearbox ten times better than the one in the Peugeot we had next (which was a heap of scrap in every respect, apart from being only a few years old at the time). So there we are :)
