I also have a Peugeot 206 HDI and have had power drops on 2 occasions.
1st time caused by loose catalyst in exhaust... it was bouncing about so that it's honeycomb holes would align one minute, then drift out of line another minute.... sometimes really strangling power as it nearly blocked the exhaust..... I realised it was the catalyst after noticing it got really hot whilst the following exhaust remained cold as struggling up a hill.To check for this you can slacken the turbo to catalyst clamp so exhaust can escape .... and power should go back to full.(you can drive a short distance on open turbo without real problems... plus it quietens the exhaust reasonably enough)
2nd time was air getting into the diesel line ..... small bubbles would get sucked in whilst parked, due to fuel draining back to tank, and sucking on a loose fuel line joint on the squeezy priming bulb pipe.This caused short power dips initially but worsened over 6 weeks until the diesel filter would collect a pocket of air whilst parked.... causing it to completely stall a short while after starting..... Usually during acceleration, the fuel surge pulling the bubble through.
..... fixes .... 1st, I cut open and removed the catalyst, and re-welded casing shut (not needed in UK diesel test) and breathes better now :0) 2nd ..... done today, replaced bad pipe with high pressure fuel line and good pipe clamps. I've ordered a non return valve for the fuel line too (not that it needs it now) ..... to stop so much air getting in if it happens again, as I guess this is pretty bad for the high pressure pump, and a pain to replace if it goes ..... .... Beware of the very high fuel line pressures after the pump in running HDI engine.
The air mass sensor can be unplugged to test ... the engine will still run normally if no other problems.

Replace spark plugs, air and fuel filter. That is ordinary mainteinance.
Ensure that you have spark on 4 cylinders.
Go to a garage and have car ECU (computer) scanned to retrieve error codes. That will tell you where problem can be.
Have vacuum system and fuel pump tested. This is done using a gauge tool.
Have compression tested.
Check O2 sensor, if the problem is particularly bad when engine is cold , also check AIT and MAF sensor.

Hi celinoid is part of the starter motor and would not cause this issue! most likely 1 of 3 things
The coil pack on these cars are really poor and dont like getting wet, you can normally tell if the car is chuggy and misfires.
the EGR valve " Exhaust gas recycler" valve this pushes unburnt fumes back through the engine to save fuel and emmissions, whe these go you normally get a warning light on the dash while the light is on the power is poor.
And finally the air flow meter or air mass sensor this regulates the air to fuel mixture if this is not working then the car either gets to much air or not enough. you can sometimes clean this part and it will work again.
Also check all the air pipes from the engine, if an air pipe is split or is taking in to much air then it will struggle to run correctly. be sure to check the undersides of the pipes.
Hope this helps
let me know if you need more info.
Regards
Dan

your ecu monitor.. emissions control unit mod is done! i dont think this is a cheap fix. either wait for warmer weather,, sell the car or find a dealer to fix this diesel puppy...word of advice .. dont buy peugeot in this country .. or any country...joke.!!
