I changed my air filter last night for a Pipercross panel one, can be recleaned so better on the environment!
Noticed that the air intake is getting half cool air from the ram effect of air coming under the bonnet and half warm through the radiator. I know old cars used to draw warm air through the radiator for winter use so it wasn't so cold but I would have thought modern engines would be a bit more advanced.
I know I could fit a Cold Air Induction kit (CAI) but as this is still under warrant I don't need to give Peugeot the excuse to refuse any claims!
Most front air intakes are ducted to just behind the front grille or on top of the slam panel in their own little catch plenum - this is neither.
They have obviously changed the old 406 low down pick-up but not put much thought into it.
You know, even your Pipercross element will invalidate the warrenty, they don't need much of an excuse you know. If it ever goes in the dealers, take it out first!

That was my plan which is why I have kept the old one.
Mind you there is a significant difference between the original and Pipercross:-
Ask for Matt and he'll sort you out. I can't comment on price as they did me a special as it's the first 407 HDi they've supplied so I was a bit of a guinea pig
The problem was there before the filter was installed (last night)
I couldn't believe how dirty the white foam was on the filter I removed, it has only done 20,000 miles!
You know some cars with Air Flow Meters don't like filters with dirt retention additives because if you are a bit generous with the spray additive you can get 'carry over' onto the MAF sensor - this could be why you have got running problems at the moment?
Clean the MAF sensor bulb *very* carefully with spirit on a cotton bud, put your old filter back and go for a drive to see if it's back to normal.

See previous post; I didn't install the filter until last night, the problem has been there for a number of days.

I didn't get a K&N as different suppliers and the web site quoted different part numbers and the sizes didn't match what I have.
K&N sell them with the promise that their filters will not invalidate any warranty nor will you have to inform your insurance company, as it is regarded as replacement filter and not a modification.
I can see the logic as far as insurance goes, after all we wouldn't expect to notify them if we use BP Ultimate! (And the real life BHP gain is minimal in either case)

NOOOOO
do not under any circumstances clean the air mass meter, the HDi uses a hot wire type which has a post heat self cleaning function anyway, after you switch off it heats up the wire to burn off any residue left there
and a cold air feed on any turbo car, petrol or diesel, is point less, once the air gets to the turbo it will be at about 150c, so all that cold air is gone
the intercooler has the job of reducing the temperature of the air
