Fault codes

[156er]

Hello.

The following three error codes came up.
Black smoke comes from the exhaust even at low loads. At higher throttle, a large cloud of smoke is emitted.
At 1800-200 rpm, with steady throttle, there is a fluctuating, throbbing rpm. There's no such thing above or below.
The error codes:
P0100
P3008
P1351

The subject is a 2009 B9 Berlingo van. 9HX engine code.

Does anyone have any idea what might be causing this?

Thank you.

We'll need the VIN to relate the faults to the correct EMS. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

Thanks

Ignore the P1351 - that's a common fault related to glow plugs / relay.

Your issue is likely to with the Mass Air Flow Meter.

Fault Code:	P0100
Description of Fault:	Flowmeter signal: Air flow not plausible. Negative difference of 200 to 300 mg/stroke between the measured air flow and the air flow reference value for 2 (for an engine speed higher than 1500 rpm).
Conditions for Fault to clear:	Driving for 5 minutes with several full load accelerations for 10 seconds
Downgrade Modes whilst Fault is active:	Use of the flow calculated Inhibiting of the diagnostics and air flow sensor plausibility Cut-off: Cutting of the EGR butterfly (turbo air cooler), EGR valve and bypass butterfly (inlet air heater) in all operating modes Cutting of the "exhaust heat recovery" function Change to "easy move" torque invalid (Deactivation of automatic mode for the electronic parking brake)
Symptoms:	Noise Diesel fuel consumption a bit higher Lack of power
Suspect Areas:	Electric exhaust gas recycling valve Air flow meter Air intake Turbocharging pressure sensor Electrical harness Leak of air downstream of the turbocharger

Fault Code:	P3008
Description of Fault:	Flowmeter signal: Air flow too strong. Negative gap for 8 seconds between the theoretical air flow and the measured air flow as calculated by the ECU: The measured air flow is greater than the theoretical air flow by 71% to 76%. Conditions of activation of the diagnostics: Engine speed between 1400 and 2400 rpm Turbo pressure greater than 725 mbar Atmospheric pressure higher than 725 mbar EGR butterfly open (doseur) Fuel flow lower than 3 mg/stroke Exhaust gas recycling valve closed Coolant temperature between 60°C and 110°C Air flow sensor air temperature between -20°C and 70°C
Conditions for Fault to clear:	Driving for 5 minutes
Downgrade Modes whilst Fault is active:	Use of the flow calculated Cutting of all the EGR butterfly actuators (Turbocharger air cooler); Electric exhaust gas recycling valve; Bypass valve (Intake air heater ) In all operating modes Inhibiting of the diagnostics relating to the air flow. Change to "easy move" torque invalid (Deactivation of automatic mode for the electronic parking brake) Switching on of the warning lamp and/or warning message: Warning lamp MIL
Symptoms:	Lack of power
Suspect Areas:	Electric exhaust gas recycling valve Air flow sensor information incorrect Air intake Turbocharging pressure sensor Leak downstream of the compressor

Thanks. I cleaned the MAF sensor. It was quite dirty. Since then, there is no twitching at low revs.
Also, I don't see it smoking heavily.

Great - just be very careful as the MAF wire is very sensitive and should be cleaned with special MAF cleaner. Never touch the wire.

Thanks for the update.

It was a special maf cleaner.
Thanks for your help.
