Default 207 gt boost issues

I have a 207 GT 1.6 THP engine here and it had lots of faults showing including missfires etc but i think the previous person looking at it was probably unplugging things on it.

I cleared all the faults and it seems happy idles smoothly starts fine and if you keep revs low it will drive ok with a slight hesitation but nothing major as soon as you get the revs up over 3500 or so it flashes up depollution and the code it has relates to overboost.

I was thinking possibly a dodgy map sensor but im not familiar with this engine i tend to stay well clear normally so im looking for suggestions also if someone knows what the reading for map sensor should be as it seems a bit high to me at idle

other thing is at key off planet says the fuel reading should be 5 this one is at 7 does that mean anything to anyone.

p0299 tends to be the blow off valve or the boost control solenoid, thats what the tsb from Peugeot says is the common areas to look at.

yeh p2263 is also the same areas, there is actually a TSB out for that fault code which is "Fitting of a protection on the filter of the turbo pressure regulation electrovalve breather pipe"

1 Split spiral sleeve - 40 mm long (Part number 6542.97) is piece needed, where u cut it to size, cover the filter of the turbo pressure regulation electrovalve breather pipe with the ribbed sleeve by positioning the split towards the breather pipe.

Personally I would probably change the turbo pressure regulation electrovalve as well to be safe and piece of mind.

Is that the only code that shows? If there are others then that info doesn't apply.....

Yes thats the only code but im not well so not got back to it yet if its up on the ramp can you reach the valve from underneath ?

Sounds like the valves are drawing in dirt through the breather pipe and once it gets in it wears them out later diesel valves had no breather.

Yeh u can deffo see it but it's all very tight and might knock off other bits. Should be 3 hoses coming off it, Service Box says the hose should be fixed to the rear of the block but most of them come round and sit on the side where the timing chain is.
