206 hdi Loss of power under 2000rpm

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.

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.
