3 Garages later and still no fix/answer.

I have a 52 reg Expert HDi, 80,000 fully serviced miles, never a heavy load lifted.

Over the last 8 months it's been slowly loosing all power.

Symptoms:
Struggles to get to 60 on a flat piece of road
No pick up when foot pressed flat.
Feels like boost from the turbo.
No acceleration.
Can barley get up hills.
Eccesive fuel consumption.
It doesn't get hot ever.
Oil levels fine.
No smoke
No tapping
No Knocks
No warning lights apart from the usual Peugeot Airbag Light.

The only bad thing I've done is running out of fuel which of coarse made the Engine management light come on, 10 months ago.

The first garage I had it in was a fuel systems specialists and he came back with no answers. No error codes.

The second garage was a Turbo specialist, fearing I might need a new Turbo I braced myself but reports from him, Turbo fine, Boost fine, Mass Air fine! No error codes.

Third garage, thought It might be in limp mode, ran diagnostics, no error codes, took it out for a test, looked at the service history, thought it might be as simple as a crappy fuel filter, took it out and low and behold it was full of sand! (1/2" of it, I live on the beach).
He replaced it, run some fluid through to clean the injectors.

I hope this is the simple answer but was hoping that maybe someone would have any other ideas on what could cause the total loss or power

I had a very similar problem with my 406 HDi slowly losing power without any management fault lights. I replaced the MAF sensor and now it goes like a rocket - even better than before I noticed the problem. It cost 90 quid from peugeot and 15 mins under the bonnet to change, it was a fairly cheap gamble considering most garages would charge that just to lift the bonnet. Looking at other threads it would seem these sensors have a finite life. Incidently, cleaning the old one with carb cleaner didnt make any difference.
Hope this is of help.

My mechanic solved my problem.

Turns out my throttle cable just needed adjusting. It wasn't sending enough fuel. Now I look back it was really stiff to press and didn't spring back

You would have thought that the first three might have found this!!
