iv had a look round yeah and can't see any leaks of smell from the car,besides a slight very faint eggy smell from the exhaust, no fault lights are showing. its just supping a rediculous amount of fuel.

possible guage fault?

very possibly but having googled the issue it seems that several people have had the issue buy I'm as yet to find what the problem was or the fix. I think I am getting a slight big of smoke from the exhaust which coukd be unburt fuel, but as to why that is iv no idea.
thanks for your reploes so far guys

Does it get up to normal operating temperature?.
The old fashioned thing to do is pull the spark plugs and have a look. If they are sooty it is running too rich.
Did you check for fuel leaks with the engine running?. The pump is in the fuel tank, so you need to check from tank to manifold.

yeah it seems to get to operating temperature fine, iv not looked in detail no for leaks, just for patches on the floor etc, I'm not to savvy with cars. iv had the spark plugs out and everything seemed fine there. and the car was in the garage for a new cat put on last week so I assume they would of picked up on a fuel leak? possibly not.

Why did it have a new cat fitted?? ... ...let me take a guess ....because it’s gone into thermal melt down due in an excessively over fueling engine or MOT fail for being massively over rich ?

hi
it had a new cat fitted as it was showing anti pollution fault and letting a fair bit of smoke to come out the exhaust, its also had a lamba sensor fitted to,not convi ced its fully stopped the smoke but the fault light has gone out, but the high fuel consumption is the next issue,would you have any idea what that could be? dread taking it to the garage yet again

Why has a cat been fitted for smoking reasons ? a cat is not there to deal with smoke

What was the fault code for the anti pollution fault ?

If the garage has told you to fit a cat because it’s smoking you need to find another garage ....one that actually knows what there doing and not a bunch of chimps loading a parts cannon and firing it at the car hoping for a fix

And when the customer has run out of money they shrug there shoulders and say go to a specialist.

For the over fueling .....in live data these areas need to be scrutinised

Coolant temp
Air mass or map sensor
Pre and post lamda data
Fuel pressure
Injection duration time

i have said this before and it does seem a little crazy but make sure there is no air trapped in the system, get hot squeeze pipes and use the bleed cap.

daughters car was the same and can only pressume air gets trapped under the sensor? who knows but a good air bleed got it running spot on within a day.(no more excess smoke/steam on a warmish day)

also check its not running on 3 cylinders at certain revs.

hi,sorry to be a numpty but how exactly do I bleed the air from the engine? where is the bleed cap located, I'll try this and see if it sorts the issue thanks

There is usually 2 bleed screws on most peugeots..one on or around the thermostat housing and usually one where the 2 heater pipes go through the bulkhead in the cabin..

the instructions on servicebox are
Open the bleed screws located on the coolant outlet housing and the heater pipe.

I think it's the fuel system being referred to here not the cooling system

part number 3 is your thermostat bleed screw,,cant find a pic of one on the heater hoses but should be pretty obvious :)

you may only find one on the bulkhead behind/left of battery looks like a tyre valve cap.
i get engine hot and wear rubber gloves, open just enough to see coolant then shut, squeeze pipes and repeat.
