Fault Help

Common or potential faults associated with the French & Italian range.


Having worked with our chosen marques for quite some time now, it stands to reason that we have come across a whole plethora of faults, failures and potential automotive hiccups. Sometimes they are quite clearly due to a lack of maintenance. Others are due to poor design. Then there is just bad luck.

Here follows a list (in no particular order) of some of the more common occurrences we have encountered. Included are our comments and/or opinions as to how 'we' have dealt with the situation or believe would or could be an effective solution. Our ramblings are by no means a substitute for competent professional diagnosis and should be regarded as bodhi for interested parties.

Affecting: Variants fitted with Sagem SL96 ECU

Increasingly we are seeing problems with the SL96 ECU. This is caused initially by coil pack failure. The coil essentially 'spikes' the ECU. Should an ECU require repair or replacement it is essential that the coil be also replaced with the new type bougicord coil pack, as this could well have been the actual cause of the problem in the first instace. Failure to do so will cause your new ECU to go 'poof' too.
Various Citroen and Peugeot models are susceptable including;-
Citroen Saxo 1.4 mpi 99-03
Citroen Xantia 1.8 16v mpi (lfy) 95-02
Citroen Xsara 1.4 mpi (kfx) 97-02
Peugeot 306 1.4 (kfx) 97-02
Peugeot 306 1.8 (lfy) 97-02
Peugeot 406 1.8 (lfy) 95-02
Peugeot Partner 1.4 (kfx) 97-02.

Another favourite whilst we're on the subject of non-starters is the 'double relay'. This fellah controls fuel/ignition systems and failure can be a cause of fuel or ignition failure (strange that innit?). The unit is usually located under or around the ECU under the bonnet, or behind the headlamp. A few we've encountered have suffered water damage and/or pin corrosion too. The unit is usually black, or a rather fetching shade of terracotta darlings. But it doesnt always follow that like colours are compatable. They are commonly cobbled together by Bitron and sport an ID number on the relay body that will resemble 1304 or 1307 or some such. The multiblock connexion is also designed so that the incorrect relay cannot be fitted.
