so you reckon that the ignition switch has a wire coming out the back of it that directly connects to the tailgate solenoid & under normal operation this wire is never fed by the ignition switch but when the switch goes faulty it starts to feed the wire to the tailgate solenoid when the ignition is switched on ? :huh:

I really can't tell if your having me on or not :)

Yeah i dont think thats a good idea, really the only way to do it is to fit an aftermarket radio. You can buy faceplate adaptors so they dont look that out of place & wiring adaptors to keep the remote controls ;)

The radio is connected to the comfort VAN network also so it can allow things like speed sensitive volume control, security coding & navigation (if fitted) The BSI is there mainly to reduce the amount of wiring & components fitted to the car + increase comfort & safety features. to be fair though the xsara & picasso are early attempts at multiplexing therefore pretty basic but they have to start somewhere. To give you an example of the benifits of later multiplexing : the mk1 C5 with navidrive sat nav is capable of the following, you are in an accident & the airbags deploy, the airbag ECU sends a message to the injection ECU which cuts off the fuel pump (no inertia switch or its wiring needed anymore), the airbag ECU also sends a message to the satnav/telephone which automatically sends a message to the emergency services for help & gives them the exact location of the car via GPS. I bet your Xantia couldnt do that :) . That system is operational in France at the moment no UK celular networks have taken up on the idea.

What makes you think that a locking problem is related to the imobiliser which is there to stop the engine starting ? I also dont see how the ignition switch could cause this problem ? The other possibility is the tailgate open switch is sticking.

Sounds to me like all of these problems are caused by broken/damaged wiring at the tailgate hinge inside the rubber sleeve.

Just get a fillament bulb test lamp connected to earth & probe each of the wires coming off the back of the door latch, when you touch the lock & unlock pulse wires in turn the locking will operate.

There is an easy way to sort it, fit an aftermarket radio :blink:

Eco mode only shuts off uneccisary electrical consumers, sidelights may be neccisary (depending on where your parked), if you notice the hazzard lights still flash but the telltale lights & noise stop inside because they are not needed. systems with a BSI draw a lot more power when the network is awake than a normal car with the ignition/accesories on.

You sure its a xsara ? they never came out till 1997 !
