[Transmission] Failing Gearbox ?

[georgeous59]

Hello Everyone my first post so apologies if its in the wrong place. We have a Citroen Berlingo 2009 1.6 Diesel Multispace manual gearbox (mileage 96K). Noise from gearbox got progressively worse over a week in Holland. noise now unbearable  just managed to drive home from Eurotunnel (Green Flag too busy)  be warned the Esso garage as you leave the tunnel is private property so we couldn't leave the car there as requested by GFlag.
 Even with the clutch out  loud scraping noise from under the bonnet, I can engage first gear  with clutch in but letting the clutch out the noise is like a banshee. It was fairly quiet in 4th gear all the way back through Belgium and France. But not anymore. As this developed over a week I thought it might be a failing clutch but I'm wondering if this is symptomatic of a failing transmission. Can anyone help diagnose what this is.   Thanks in advance

Off the top of my head, if it's noisy with the clutch in then I wouldn't think it was the gearbox as nothing is turning in the box then? Maybe clutch release bearing failed?

Maybe take the starter off and see if you can get a fibre optic camera in as first port of call?

A bit of a mix of symptoms, but if the noise is there in 4th gear (when the gear train is effectively locked) then it could point to a bearing mainshaft failure, but the screech sounds more clutch related. Either way, the gearbox will have to be removed and you'd normally replace the clutch at that point, even with a gearbox problem. 
Have you looked to see if there's any oil in the gearbox?

My money's on a knackered release bearing / figures of pressure plate.

Noise in 4th has only just turned up the previous 4 days  there was no noise at all in 4th gear but noisy as hell now in all gears  , Car is regularly serviced (not by me )  Thanks for your input. The Oil question did pass through my mind ..tbh

Telephone conversation with garage thought it was a failing thrust bearing in the clutch, It got progressively worse. 
In neutral with clutch in  =no noise then with clutch out in neutral excessive scraping whining noise . 

Thanks for the advice

Originally called garage while we were in Holland he thought it was a failing thrust bearing in the clutch. I 'll probably get it recovered to a garage and get it sorted . Thanks  for your advice .

I had to get mine done last year, it was the thrust bearing which had welded itself to the guide tube, ended up with a full clutch getting fitted even though the pressure plate and friction plate were ok. The noise was horrific even though it kind of drove ok, but it would have woken the dead. Developed very quickly too from starting to make a noise, to "omg wtf is that" kind of racket.

Tell me about the noise we drove through a small cul de sac at  mid night from the Eurotunnel . Neighbors must have thought WW3 had started
