Xantia: key light flashing and beeping
I have 2 HDi Xantias with the key light flashing and beeping which won't start.
I presume there is an issue with the immobiliser, is there much I can do without a lexia?
I have another HDi which starts, what would I need to swap to get the dead one started?

Re: Xantia: key light flashing and beeping
Not necessarily a fault with the immobiliser, the engine ECU may not be powered up & this will also cause the key light to flash.
Things you can do without lexia are check the inertia switch has not been tripped.
Check all the fuses.
Unplug the MAF & check all the pins with a voltmeter with the ignition on, do you have a 5v & a 12v feed ? if so then the ECU is powered up.
As far as your other car goes you would nee to swap the injection ECU, the CPH (behind the glovebox) & you would also need a transponder chip from one of the keys.

Re: Xantia: key light flashing and beeping
I had similar situation a few years ago. It turned out to be an intermittent connection on the 'aerial' surrounding the ignition key barrel. When that happens the immobiliser will not 'see' the key and hence refuses to allow an engine start.
Solution was to remove the cowling around the key barrel and carefully check the wiring, it was a loose connection.
Fortunately removal of this cowling on mk2 Xantia does not involve removing the steering wheel as it does on the mk1 although it is still a bit of a faff.
Good luck.

Re: Xantia: key light flashing and beeping
There is no voltage to all but the last pin which reads 1.5v of ground.
I dunno if this makes a difference, but the key left in ignition warning works.
Also have a series 1 activa that won't start, i have the code and seems like it is not getting fue, I checked all fuses and relays to no avail.
I have another series 1 activa that does start, do I just need to swap the ecu to test if the dead one car will start?

Interesting...
I have a Mk2 HDi, which very occasionally fails to start, with the key light flashing and beeping. I just turn the ignition off then on again, and away I go.
It does, however, show other symptoms of a dodgy connection somewhere, namely the speed of the interior fan varying by itself sometimes. I've had other people suggest the ignition switch with regards to the interior fan.
I think I need to look at the connections on the back of the key barrel then!

Re: Xantia: key light flashing and beeping
The fan problem is likely unrelated and due to either needing the "relay mod" (or said mod doing better than it has been) or new brushes in the fan motor itself.
The transponder aerial is separate from the ignition switch, it's just a black plastic "sleeve" over the outside of the barrel with very thin wires plugged into it.

Re: Xantia: key light flashing and beeping
Without hi-jacking the thread, do you have a link to the relay mod?
However, my fan is squeaking slightly, so I suspect it's just goosed. I found out through ebay that you can get a fan from a Range Rover, but I'll double-check part numbers before ordering.

Certainly, it's in the stickies at the top of the page under XANTIA BLOWER WORKING INTERMITTENTLY
The brushes can be replaced in the fan, and it has been done with success on the forum before. Thread hijackery is par for the course on here & IMO the forum is a better and more useful place for it. All the same, apologies for the OT Dave & hope it's just the aerials on your pair of HDi's

I don't think it's the brushes though. The bearings at each end of the motor look rusty. I actually got some white Lithium grease into the bearings, and that quietened it down for a week or so, then the squeak came back. As I said, I think it's goosed. The bearings seem to be the sealed type, so not easily serviceable.
Re: Xantia: key light flashing and beeping
i checked the wiring for the barrel, the sense if key is near ignition works.
there is no power to MAF, so i guess there is a fundamental issue with the ECU.

Re: Xantia: key light flashing and beeping
So after fiddling with the ecu and double relay and loads of contact spray, one started!!
The other no longer has the flashing key symbol, but still won't start.

Re: Xantia: key light flashing and beeping
Now we're making progress, glad to hear it is this the pair of HDi Activae you're working on? Really wish I could offer a home to both of those, they sound like they could be the best of both worlds. Decent power/torque and economy coupled with legendary handling and comfort (only way they could improve IMHO is if the base car to fit both HDi and activa system to was either a CX or XM)
I'd have one manual and one automatic...
Dreaming aside, have you got any power to the ECU now on the non-runner? If fiddling with the Bitron/wiring has resulted in a change but no improvement the fault has to lie in something you've moved.
Perhaps double check the voltage (AND current available, with a 21w test lamp) to the double relay in that car & if that tests good try swapping a relay from a runner. Really hope to see these pair saved and kept within the forum as I would love to know what they turn out to be like in real-world driving.

Yup my crushed dreams, and obivously the one that won't start is the better of the two with dark interior roof.
there are some plugs not plugged in - J802 L802 H802

Tried the relay from a running one.
I'm not sure what is the best way to test if the ECU has voltage.
why?
Re: Xantia: key light flashing and beeping
So it's a fuel pump issue on the HDi Activa - took the lift pump out - clunk is what it makes.
How do I clean/fix it up? i can't figure how to pull off the pipe at the bottom.

Re: Xantia: key light flashing and beeping
swapped the fuel pump with one that works for now, still not starting!!! argh!!
fuel gets to fuel filter under bonnet. relays seem to click.
it has 12v and 6v at the MAF.
What am i missing??
