help non starter citroen xantia!

[Hell Razor5543]

Before you buy a Lexia off e-bay, seek advice. Some are OK, others are not so good. The Chinese clones don't work over version 5.29 of the Lexia software (at this moment).

Your best bet could be Diagbox. It is more expensive than a lot of the Lexia clones on e-bay, but it seems to be more reliable, and there is a good aftercare service. They also (apparently) knock off £10 to FCF members.

Good call hell razor thanks im buying that one he does give discount fyi just waiting for him to invoice me via paypal and it should be here dayafter tomo...now if somebody could advise me on the ecu dilemma hopefully i am set! Do i buy an ecu with the same code but no chip or ecu with diff code but for same engine with texton box and ignition and key etc which will be easier to recode or whayever i have to do to it....thanks

All the Lexia is likely to do - in the short term, considering there is no K light on - is tell you the ECU status. Providing it says "unlocked" then the problem is either electrical or the ECU itself.

Okay, this is what I what I think it is: A fault on the ignition telling ecu to cut fuel and ignition (cracked spark plug / bad lead) or Bad Fuel.

So ...
I'd check all spark plugs.
I'd see if I'd check to see the fuel coming out (smell of petrol in cylinder).
Then I'd disconnect the ecu for 3 hours to blank it.
Then I'd reconnect and try again and see if I hear a different noise.
If different I'd change the plugs and try again.
Then I'd drain the fuel and refill with 'clean' petrol.

Quick question. Does the 'K' light come on when you turn the key to position 2 (but not the start position)? As far as I am aware, it should come on (and stay on) until the engine has been running for a few seconds (unless there is a problem). Well, it does on Gracie, which (I hope) means all is well. If it does not, it would suggest a blown lightbulb.

The reason I ask is that you said you hadn't seen the immobiliser light come on. It should, but just for a moment.

Fuel pump is working...fuel is fine drove 30 miles on it and and stopped and started ...i have never seen a k light i get the stop,battery,(stop flShes unless i put foot on the brake, a couple of aorbags,suspension pump thing and abs no key light ever...not in the year or so ive owned it

[Hell Razor5543]

Then that suggests a few blown light bulbs on the dashboard. The 'K' light is in the 'CONTROLE' group of lights, bottom left row, yellow, and looks like an engine with a 'K' shape in it. I've found a webpage that shows that group of lights, so I hope it helps;

I know that this doesn't help with the main problem, but when you get that solved, having all the bulbs working can be useful.

[davo123]

Heh yeah i bet i hadnt ever heard of a k light til you just mentioned it
well ill carry on tomorrow.night and thanks all for your help...ill keep you updated.

[addo]

It sounds then, like definitely two things worth investigating - the globes for K and transponder telltale lights on the dash.

Tell you what - here's one simple test for the transponder. Take off the column shroud (top/bottom parts) and unplug the transponder aerial (small, squareish black plug). Put in key and turn ignition to "on" - see if key symbol lights up in bottom of tacho.

I have watched the light sequence on Gracie so I could let you know which lights came on, and the order they go out in. My Xantia is an HDi, so there will be differences. The one I know of (and will only mention here) is the glow plug light. If there are any lights on your Xantia that are not on mine, I won't know of them.

When you turn the key to the 'M' position, lots of lights will come on, and then some of them will go out. The order they go out is as follows;

Immobiliser light will go out (Rev counter, lower right. It won't have been on for long). Then (in the CONTROLE group) the oil level warning light (if it blinks for 15 seconds the car is suggesting the oil level is wrong), followed by the ABS light (this may come back on as you start the car, but it will go out again). Next (in the CITROEN group) the airbag light, followed by the side airbag light (looks like a seated person wearing a safety belt with a balloon beside them).

There are now several lights that will stay on until the engine is running. The lights that are still on are;

In the CONTROLE group, the 'K' light, the brake warning light, the stop light, the oil pressure light (looks like an oil can), and the battery light. Below that group, the coolant warning light. Over in the CITROEN group, the handbrake light.

When you start the engine (I know, it won't at the moment) the oil pressure, coolant and battery lights should go out almost instantly. The the 'K' light after a second or so. Finally, once the hydro pnuematic system has got to its operating pressure, the brake warning light and the STOP light will go out. The only light that should remain lit is the handbrake light in the CITROEN group.

If you need to replace some bulbs, the general concensus is that it make sense to replace all of the bulbs (as it takes about an hour to get the dashboard etc. out, swap and re-fit when you know what you are doing). Get about 40 bulbs, (this will be more than you need , but not a lot more). Citroen charge above the odds, GSF didn't have any when I needed to get some, so I got them from Unipart (part number GLB286BXT, 12 V 1.2W). There are two bulbs of a different design used in the heater control, but I don't have the part number.

I hope this helps.

PM me some details about the car as I might buy it complete. Mileage, MOT, rust, interior condition, etc. I'm assuming its a Forte or LX spec. if its only a 1.8i lump.

service citroen only shows a single coil pack for all MK2 petrol XANT's except the V6,

who told you they have separate coils?????

There are 2 seperate coils on the 16v (ie 2 sets of windings) but they are both moulded into the one unit, One side sparks cyls 1 & 4 at the same time & the other side sparks 2 & 3 at the same time, either set of windings can fail seperatley, I assume thats what he meant.

[addo]

Have you ever played mix and match with the coils off different motors? I don't mean as half a pair, but visually (at least) the coils for a TU5JP4 look remarkably like what's under the cover on an XU10J4R.

[davo123]

Hi its an lx everything worked on it except drivers window,mechanism works but it fell off its runners so wedged shut with a piece of wood,apart from that and airbag lights on dash it was very good until it gave up!
