Hey Guys,
I have the car for over a year and drove it around 40 000km through the year. Currently car has 140 000km. From time to time was throwing error code PA200A21. Recently it went into a limp mode also. At home it showed me:
P200A21 - The charge movement flap (cylinder 1) has a malfunction. The signal amplitude is less than a minimum amplitude
P246309 - The soot content of the diesel particular filter is NOT OK
P200A75 - The charge movement flap (cylinder 1) has a malfunction. The emrgency position was not reached.
I have played with charge movement flap using SD and it got better. There is no problem with the electric motor operating the flaps as it is moving correctly according to SD. Car did not throw error for another 2 days. However yesterday it came back with P200A21 but only as stored and not current. It showed me 6 occurences of this error. It usually happens when car is being driven at low speeds we say in the city. 80% of my driving is the motorway driving.
It has power etc. SD is showing DPF actual values great - no problems there at all. All the sensors are functioning fine.Only one time it wasn't able to regenerate the filter. My question is - should I try to take out the intake manifold and clean it - which is not a pleasent job to do - or I should get a brand new intake manifold? I have taken a look under the car to see if the intake manifold is cracked etc. however engine is dry in every place where I was looking into so this is not a problem. I know there was an issue with a screw on these intakes so what would you do at my place?
Also if you would clean it - which chemicals would you use as it is a plastic intake?
