Our Peugeot 206 1.4 hdi has no power under 2000rpm. as the car gets
warmer the power will some times not cut in untill 2500rpm. :( Scary
when accelerating on to duel carageways 8O

If the weather is frosty the car seems to run better with the power
coming in at 1800rpm.

If the Air Mass Meter is un-plugged the power is there from Go up to
2000rpm then fades out. So you might think that this is the problem.
Not so as we have replaced the Airflow Meter without any success.

The two local Peugeot dealers are of no use at all :roll: and have
not been able to fix the fault. One even replaced the Cat to try and
fix!

The car has now done over 100000 miles since this fault first occured
so i’ve got used to it being slow but can anybody help.

Have you checked that the engine fans are working and keeping the
intercooler cool. Clue you say it works OK in frosty weather,
Mike

Hi,

I have no help for you to offer but have the same problem with my 307 2.0
HDI (107hp). Power below 2000 rpm is way to low then above ca. 2000 it
accelerates like I would expect it. The car also reaches max. speed. Peugeot
dealer replaced the airflow sensor as well - no difference. Also replaced
air and diesel filter.
I can't really say it changes with the outside temperature but it happens in
a range from 1800 - 2500. I'm highly interested to solve this.

Regards,
Marc

That is how the power is delivered in that engine that is why they can find
nothing wrong. If you want punchy throttle response all the time you have to
keepo the turbo spinning well and that doesn't start to happen until after
about 1700-1800 rpm and then drops off again just over 3500rpm.

Try driving the car around town in 2nd and 3rd and you will feel a
difference in the response, don't stamp the throttle and keep it in the
range 1500-2500 and it will stay economical and responsive.

I have never driven the 90BHp HDI in the 206 but I would assume the power
delivery is very similar, probably not helped by that car not having an
intercooler (I'm almost 100% certain of that) and a different turbo to the
110BHp unit, so it is more affected by temperature changes.

Hi Chris,

thanks for your response. I've driven a 1.6l 110hp 307 as a rental car once
and experienced exactly what I would expect from a Diesel engine (high
torque in low rpms). My 307 2.0l HDI is delivering maybe 20-30hp below 2000
rpm (from my feeling) and it can be quite dangerous in some traffic
situations...

I should have said that I bought it used with around 110 000kms.

Marc
