I bought a used Peugeot 406 1998 model 2.0. A while back, I took it in to have the cam belt and CVs changed, after that I noticed that the engine will suddenly start revving by itself when it is idle and sometimes when I'm moving. Not long after that, the intstrument cluster stopped working. The only instruments that were functional were the temperature guage and sometimes the fuel guage. I took the car to a Peugot dealer here in South Africa and they changed the ECU, injector valves, clutch systems, fuel pump and speed sensor. They tinkered with the cluster too but could not fix it. I was advised to buy a new cluster. In the meantime, the revving problem was solved but soon afterwards the engine began to cut out in mid trip, on its own, especially when the temperature rises, it feels like the fuel supply suddenly cuts of. I would then have to switch the engine off and restart the car for the engine to pick up again. This will happen 3 or 4 times during my trips and will only stop after I switch off the engine for about 3 hours and it has cooled down. I took it back to Peugeot and they have been running tests but still can't seem to find the fault Can some one please help?

Re: Engine cutting out in mid trip
Put the car on an oscilloscope and check what is happening,check cranksensor,injectors,fuel pump supply,coil packs you will then see what you are loosing if its power(electrical)or a fuel problem put a fuel pressure gauge on it and road test it you will then see whats happening.........oscilloscopes dont tell lies.....

the fsm covers this. but what engine>?
to work on engine, you must know what is there.
1.6 thru 3.0 both gas and diesel.
fsm = factory service manual.
ive locked many a cam, the books show how.
some cams have hex flats to use wrenches (mazda)
others DOCH use cam cog wheel locks
others have SOHC, cam pin hold that you lock with a simple drift pin
the FSM shows this fact, on all cars made. any engine.
not only that you didnt say what step you got stuck?
of the 50 steps.
at the crank pulley,? 1st steps? or are you locking the cam
so you can time the belt. (way far in to install section)
you are have what is known as a dry tappet. last for 5-10 min on startup. now you can leave it or you can change the oil and filter. when changing oil I mean you use oil treatment first to remove the old oil deposits. then change the oil. the only other way is expensive removing the cam's that involve taking of the timing chain and other parts to remove the dry tappet and clean out the vaine. but usaly a good oil change will fix this problem..
undo the bolts on the alternator and swing it inwards towards the engine,replace the belt and use the alternator to tension the belt with a long tyre iron,the belt should have 1/2"play in the longest run.(yes it is that simple)
you mean the timing belt i presume ,ten years old low mileage but its the age ,the belt may be ok but take the top part of the cover off and look at the belt ,if you can the shape of the teeth showing on the back of the belt then change it as they only cost 16euros for the petrol engine and they are very easy to change done one yesterday andf it took me all of 20mins .
usually you should do it for peugeot diesel at 122000 miles along with water pump and the tensioner roller that runs under the cambelt too. But to be on the safe side do it at 100000 and save the fortune.
It took me (DIY job) about 6-8 hours as i wanted to save 450 pounds.
In general, aside from specific manufacturers recommendations, The service life of cam belts is between 45 and 60K miles. This is an item that is not to be ignored..belt.failure can cause catastrophic failure inside engine.
