Expert 2.0 HDi Loss of power

I have a problem with my expert van 2.0 HDi, for the last month it
seems to be very sluggish, poor accelaration. its bearable around town
but on the motorway its realy hard to keep at any decent speed.
in third gear it accelarates slowly then as soon as I hit 50mph it gets

a spurt of power, I have to take it to about 60mph then change to 4th
again it slowly creeps to 70mph then it bursts into life and will go to

about 85mph plus . if i change to 5th it will keep at a steady speed,
but if the revs go down (due to hills etc) it will not regain speed. I
think it has something to do with the turbo charger. I would
appreciate any of your oppinions before I book it in to be repaired..

Thanks in advance

Ps. the van is always full of tools etc. but I its always been fine in
the past..

 

I have exactly the same fault with my 206 2.0 Hdi Dturbo. It happen
yesterday in when driving through a storm. I have taken the air filter off
and the filter was soaked.

The result is a big loss in power/acceleration and sound exactly like the
problem you have.

I have replace the air filiter with a new dry one but there is still no
power. I think water may have got in through the intate.

I spoke to a few friend about this and they say that the ECU may have gone
into limp mode? And the ECU needs to be reset.

I have no idea what the problem is but i'm gutted. Have you been through
any water recently?

Regards,

Chris

 

To reset the ECU just disconnect the battery for a few mins then
reconnect.

 

I found out what it was!!!!

It was the mass airflow meter. cost £130 from Peugeot dealer easy to fit
and car is back to full power.

Hope this helps!
