Peugeot 307 XS2004, 2.0 RFN, 9.6 tkm
The following is a listing of some symptoms that may occur. Depending on model, there might occur others.
I have been told intermittent misfiring and illumination of the EML or Check Engine Light can occur. It's possible that this might occur, but i haven't encountered that symptom on the RFN engine in conjunction with this specific code ( P0352 ).
Since the ECU reports fault encounters through the EML ( Check Engine light ) while the engine is running, in this case the fault will disappear if the engine starts, and the engine will cut out immediately if the fault returns.
Therefore i find it very unlikely that the specific code ( P0352 ) will light the EML and will base the following text on the above listed symptoms. A fault in a different coil ( cylinder ) might lit the EML but in that case the code is P0351,P0353 or P0354.
As with all intermittent faults, locating the faulty component might be a challenge and a OBD-II code reader comes in handy.
The fault codes should, as always, be read and interpreted keeping an open mind, since the stored fault code might refer to the part/component that detected the error. OR the pert/component that supposedly might cause this fault.
Meaning, the component blamed might be failing due to a bad connector, damaged wiring or poor grounding.
On this vehicle, the ECU had stored the fault codeP0352 .
P0352 = Ignition Coil B Prim/Sec Circuit malf.
This 307 was equipped with a COP- ( Coil Over Plug ) unit, meaning there is a coil located on top of each spark plug, and this is the unit to which the ECU is referring. To be specific, the coil for cylinder 2 ( P0352 ).
Without diving deeper into the function of this unit, we state that it is located under the engine cover and between the camshafts. It stretches almost over the entire length of the engine, but is only mounted with 3 bolts.
Faults in these units are rather common and more likely than failing ECM- ( Engine Control Module ) or PCM- ( Powertrain Control Module ) units.
Nevertheless, the 3 mounting bolts that also function as grounding/earthing should be checked.
Also check the COP-unit connector and the wiring for signs of damage or oxidation.
This specific vehicle showed nothing out of the ordinary and a new COP- unit was installed.
Some parts, non original, CAN have a built in oddity, and MAY need the engine to turnover ( one turn ) before the engine starts.
This seems more like a trait than a sign of a faulty component.
As far as i have seen, except for this slight delay, these components function as good as the original.
Removal
Reinstalling
The opposite of removal, but with a few things to keep in mind.
When the unit is wiggled and pushed fully down, the securing bolts should be tightened evenly.
Start with the middle bolt and tighten it a few turns. Then follow up with the ones on the sides.
!! NOTE !!
I have been told COP-units should be handled with care since they are sensitive to impact or shock.
To what extent that statement is true - i can't honestly say.
It might be one of those urban-legends, but since i can't say the COP-units are NOT sensitive to impact or shock..
Handle the COP-Unit with care, since it IS or MIGHT BE sensitive to impact or shock.
- Intermittent unusually long cranking before engine starts. ( No EML )
- Starts but stalls immediately.
- Engine cranking but don't start.

- Remove the battery negative pole
- Remove the engine cover
- Carefully release the connector socket at the end of the COP-unit. Inspect it for damage or signs of oxidation.
- Remove the three ( long ) bolts securing the COP-unit.
- Grab the unit at the ends. Whiggle and pull it
straight upwards .
