V6 Xantia......... the beginning of another adventure

[Trainman]

No Simon, the other way round, Paul's was working on the Xantia, so we plugged my lead into his LEXIA and it wouldn't work.

[citroenxm]

yes we did, and there IS a fault with Steves cable. Its a strange one, and currently the only one on ebay. It has the Large brown Xantia S1 plug one end, and rather just plugging into the Round Lexia socket, it plugs into the D shape ODB type socket...

Mine, on the other hand goes to the round lexia connector.. Mine worked perfectly.. and as steve said, theres NOWT wrong with the box, it only didn;t like the Stop Light Switch, which we found the problem and sorted to..

My Lexia is the same - 16pin OBD-II to 30 pin adaptor rather than a direct cable to the round plug. I believe most of the Lexia's for sale now are the same. I've never tested my 30 pin adaptor works though for lack of a 30 pin car...

You mean you pressed the brake pedal ?

[citroenxm]

nope, we removed the pedal Switch from the car completely, as also the cruise doesn't work.

So messing around with the first one we found a dodgy connection at the switch in the wires.

So I swapped the pedal for another one, and cleared the "Stop Light Switch" fault, but cruise still doesn't work, but the autobox has NO issues at all..

The autobox fluid by the way is nice and clean and quite clear!

[Trainman]

Nor did the cruise work on the way home, we've replaced the brake pedal switch, as Paul has said, the vacuum pipe is connected, and it still won't work.....

[Mandrake]

On my cruise control the vacuum purge electrovalve had failed, I replaced that and fixed the brake pedal switch contacts and it works fine now. See the thread I linked to earlier on how to test the vacuum pump and purge solenoids - it can be done by unplugging the ECU between the seats and using some jumper wires to manually energise the pump and solenoids...

Interesting about the brake pedal - if the gearbox ECU though the brake was being pressed all the time it would have affected the up shifting! Mind you the same contact feeds the brake lights so that would mean your brake lights were on all the time too...

[CitroJim]

Oh and the gearbox.......


Nothing...... that's right.... Nada, zilch, zip, nowt....

That's so frustrating Actually, thinking back the car has a history of this... I recall several years ago it happened when Roger Bradford had the car and I put my Lexia on it and not a sausage to be found. It happened again when Jason had it and although it wasn't Lexia'd then it disappeared never to return until recently...

Most bizarre. I do have a spare S1 ECU (the S2 one is very different) and if it happens again it'll be worth swapping them over but the occurrence of this problem is so random and infrequent it might be years yet before it happens again...

Yes, what's news of your Lexia Steve?

[xantia_v6]

It is. while ago, so my memory could be wrong, but I think that there were no residual faults logged when my multiswitch failed (even though the transmission was in limp mode for about 3 days).

The multiswitch. can be diagnosed (when it is playing up) by measuring the voltages with a multimeter while the fault is present (ignition on, engine not running, selector in D).

[Trainman]

The only other thing worth quickly mentioning is the radio, working fine when I left, turned it off to answer a call from SWMBO on the handsfree kit and the flaming thing wont turn on again, I have the feeling that a fuse has blown, but don't know yet.

I'm at work at the moment, so I will do the full report tonight, when I get home.

[Trainman]

The heater matrix had been leaking from various places as can be seen in this pictures







Also there was corrosion damage on the water pump




Oh and Jim the evaporator is tucked away at the back of the engine on the bulk head

[CitroJim]

The heater matrix was gone in the usual place Steve. I reckon the matrix itself is OK and if just the O rings in the (inaccessible) joint were replaced they'd be OK again.

[Trainman]

Wonderful could have saved myself 70quid and just bought the rings......

I'm off tomorrow so having a look at the radio, and the headlight that needed replacing is plane spotting so needs to be adjusted, once that's done. I need to get the good tyre I have on the spare put on the alloy then she can be valeted.....

I hate a dirty car

[citroenxm]

Naughty jim again..

Id never reuse a matrix after taking it out.. did that once. We rescused an almost new matrix from one car went to the trouble of fitting it to another and two days later it went pop... so we had to fit another.. so steve no it was 70 quid well spent indeed!

[Trainman]

I know, just me being tight....... LOL

[Mandrake]

So now its (presumably) running and driving normally, how do you like it Steve ? Was it worth the effort ?

Although I've had ups and downs with my V6, when it has been running properly its definitely one of my favourite cars I've ever driven and my favourite of those I've owned... That's what makes me keep trying to get its niggles sorted out rather than give up on it...

I've always liked Xantia's but the V6 puts it in another class over the 2 litre models...

I'm also curious to know how well it performs on LPG vs petrol ?
