Peugeot 307 2.0 HDI Cleaning of throttle plates and intake manifold

Peugeot 307 2.0 HDI
Cleaning of throttle plates and intake manifold.
Cause: loss of power.
The lower flap was stuck due to a large amount of soot in the intake manifold.
After cleaning, the car drove briskly again.

It's unbelievable, that there were so large amounts of carbon deposits.

[@petriukasp]

Are there any issues when its this dirty ?

It's hard to remove intake manifold and egr valve ?

[@allsknv]

There's practically no access, very little space. To do this, you'll probably have to remove the engine from the cushions

Ok thanks

[@CozzaNess]

Did you manage to remove the parts with the engine in situ?
