Hi
When cold, car starts perfect on 4 cylinders.
After 2-3 minutes of warming up and driving (on idle anything occurs), the car shows message antipollution fault, then catalytic converter fault, and (this is really strange) ABS/ESR fault (and ESP deactivates ), and car runs on 3 cylinders (pof-pof sound, vibrations...). And MIL switch on. 
If I stop engine and restart, car runs well for 10-15 seconds and then messages again and 3 cyl.
I did a scan and this are the results:
P0300: Random Misfire
P1336: (no description)
P0341: Camshaft Position Sensor Circuit Range/Performance
It's not spark plugs, or ingition coils (changed both).
I also think I can discard a compression issue, because for the first 2 minutes the car goes well. If its open valve it would be failing always.
I think injectors could be the problem. But then again, P0300 means a problem on various or random cylinders... which sounds strange if one injector is failing. 
I think EGR it's okay because I checked with OBDII while engine was running and it opens/closes OK.
The code P0341 related to Cam sensor... could a malfuncion on sensor cause going on 3 cylinders? Sounds strange. I think P0341 its more a symptom than the cause of the problem.
Maybe MAF/MAP failing?
Any advice will be appreciated!

worth a try vvt solenoid give it a clean, might not be the problem but worth a go, it normally makes the car run like a 1.2 but not heard it giving a misfire

Looks like your camshaft sensor is playing up. Take it out and clean it up, might need replacing. |

So I get both CAM & Crank errors  I localized Cam sensor, though I don't know how to remove it for clean. No idea where is Crank sensor
Appart from that, I think that maybe ECU is disconnecting some cylinder when detects a misfire, in order to preserve catalytic converter. Do you know if Peugeot ECUs are "so intelligent" to do that? I say that because car goes bad just after throwing all faulty messages, and I know some cars do that.

I would ignore P300 completely, i more than likely just think its a ghost code created by the misfire caused by the other codes
Try another camshaft sensor since there is two codes of this item, and i doubt you have the facility to scope it, so get a second hand one cheap and just replace it
See if the fault clears and the vehicle runs right

It's a good point. I'll check CAM sensor. Peugeot Part number is 1920 8W ?
I think is this one:
but how I remove it? Thanks again

Not sure on the 180. But on the 138 gti it's on the top back right, it's essentially the same head, so should be the same place.

if I disconnect the cable that reachs to the cam sensor, could I damage the engine in some way?
Do you think its worth a try to get some conclusion?

What about the coil pack playing up. Make sure you have a good spark on each plug. Can cause the Ecu to throw up a sensor code.

as I said its not coil packs.
I bought a new cam sensor, should arrive in some days. Lets see if it works...
If not, I'll try injectors...

Apparently solved - run the car for 15 minutes and everything OK 
This confirms that BSI disconnected on purpose some cylinder when getting wrong data, I guess
