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.
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.
