Hi guys, does anyone have access to the wiring diagrams for the engine wiring harness? I have several errors in the MSG and BSI and the car won't start. e.g.05FF, P0103,P0336,P0342,P0727

It's a C5 2.0HDI

from 2009

Greetings Martin

Here is the injection diagram.

You have 2 parts that will cause issues: Your flowmeter looks to be faulty - so I would get that cleaned or replaced as this will affect other aspects of engine management, as the engine ECU will use default values in the absence of any actual data from the flowmeter.

The other 2 codes relate to the engine speed sensor, so I would get that replaced first, see what faults remain and then deal with the Airflow Meter (MAF).

Fault Code:	P0103
Description of Fault:	Flowmeter signal: Signal period less than a minimum threshold. The flowmeter signal period is less than 60 µs for 400 milliseconds, which indicates that the flow measured is the maximum.
Conditions for Fault to clear:	Ignition on
Downgrade Modes whilst Fault is active:	Deactivation speed limiter until the next time the ignition is switched on Deactivation cruise control until the next time the ignition is switched on Deactivation of the particle filter regeneration forced by the diagnostic tool The ECU stops the regulation of the EGR valve Switching on of the warning lamp and/or warning message: Warning lamp MIL
Symptoms:	Smoke from the exhaust Lack of power
Suspect Areas:	Air flow meter Electrical harness Connector Engine ECU

This may be a faulty Crankshaft Speed Sensor - again this will cause issues if faulty.

Fault Code:	P0336
Description of Fault:	Engine speed signal: Absence of signal under starter. Absence of signal from the engine speed sensor on starting.
Conditions for Fault to clear:	Under starter
Downgrade Modes whilst Fault is active:	-
Symptoms:	Starting problem
Suspect Areas:	Engine speed sensor Engine speed sensor target Electrical harness Connections

Fault Code:	P0342
Description of Fault:	Camshaft signal: Signal absent. Loss of the camshaft signal for 2 to 3 engine revs.
Conditions for Fault to clear:	Under starter
Downgrade Modes whilst Fault is active:	-
Symptoms:	Starting problem
Suspect Areas:	Camshaft sensor Target of the camshaft sensor Timing Electrical harness Connector
