My "love" of all things xantia...and Xm...and Cx..

I must admit ive never been able to hear the valves making noise, i hear clunks but no buzzing!

My software has the scope function, but i dont have the hardware!
Ill have a look at the connector and test the voltage.
I remember when i took the ECU apart, one of the chips looked as if it had taken a bit of heat, but nothing dramatic.
Citroens dont leave much time for dissertations fo they!

Went to the coast today, rather nice! Bit of a bumpy back end though!
Will really have to have a look at the electrovalve!

I ended up taking the door card off the passenger side today, as i though only having 1 working window was a bit ridiculous. Turned out to just be corroded connectors to the motor., so cleaned them and greased them.

On the way back it was a bit nippy, and the heating did sod all, i wonder if it has anything to do with the engine running at 60 degrees? Must replace the thermostat!

I also noticed that when i sit in the car after the engine is turned off, there are intermittant loud clunks and the cr jolts and sinks a bit, is this normal for the electrovalves to do this?

Having re-tested with the lexia, it appears that just one ABS sensor is at fault

Much better that 3. None of the other intermittant faults have come back which is a relief.

So is this über rare v6 Xm auto coming your way then Dave!?

What kind of owner strips a series 2 V6 down as spares for another Xm!?

Must be one of the rarer modern Citroens after the Prestiges of course!

What colour is the car (missing panelwork)?

Andrew

Hopefully it is Andrew, the guy said he would contact me at the end of may when he was able to get to it, so i will no for definate then. Then it may be a trip to see Dean for the front end!
Shame its not a 24v, then it would be uber uber rare!

He said it was the MPG that made him take it off the road, really it needs LPGing.

I believe it is blue, which would look really good once done up!
Sadly i dont think it will be done for any of the rallys this year, but next year i will hopefully have the white Cx and the V6 ready to rumble.

Did you hear about the Xm collumist for the Citroenian having his S2 V6 stolen, which had slight front end damage and it was a dark colour too. Hope its not that one!

Your really building up a collection now Dave, your going to be run off your feet with all of these Citroens

I did, there are some right gits out there! No i think this one is genuine, the guy didnt seem the tyoe to be nicking them being a citroen mechanic!

I felt run off my feet with just one never mind 6!

I was hoping to update with pictures of my finished sphere pressure tester today!

However when using the 4.5mm flare tool, the fipe did not flare and seems to have expanded inside the bolt

Means im left with a knackered flaring tool and no tester!
Need to buy myself a load of drill bits to get the pipe out!

I finally managed to get the correct thermostat for the car today, and it now runs at the correct operating temperature of 80-90 degrees

, which is great but i keep thinking its overheating as it used to run at 50!

I have ordered a new drier unit, as despite getting it regassed etc at slofit,(the same ones who attached(or didnt) my spare whhel so it fell off in the road on the way to work) i noticed a leak of green fluid around the pressure sensor, and its cooling capability is poor to say the least.

Small update, I replaced my vno5n for the rear electrovalve and success

I can now hear a buzz from the rear (but no buzz from the front)
and the lexia confirms that there is no longer a fault!
We will see if it performs any better, i didnt notice any difference today, but i hadnt cleared the faults then.

I do also wonder if the ride height at the back is high, will have to compare at a rally!

Unread post by **CitroJim** » 22 May 2010, 20:26

That's a good start Dave

Now, ride height is critical. If it's high and it seemed to be that time I saw you driving (bouncing) along the streets of Norwich.

I don't know if the finger test holds good for the XM but on a Xantia the more or less correct ride height is one finger between top of tyre and wheel arch and the rear and three at the front...

Looking where the front Hydractive valve is on an XM, you'll have a game hearing it. Whoever thought to put a sphere there was having a laugh...

Is the rear Hydractive centre sphere a known good 'un?

davetherave · Unread post by **davetherave** » 22 May 2010, 21:28

I dont think the finger trick will hold up at the back as the tops the tyres are hidden!

Usefull to know for the xant though, the rear hydractive sphere is brand spanking new (I think?) Im sure ill find out by reading back through the blog! But it does look clean, and i seem to remember thinking bugger, why put an exhaust below the damn thing.

Just been outside and given it a clean so she is looking half decent, just need to deal with the rust

.

Next Big Job get the damned ABS sorted.

Well today i decided to investigate why the engine has had oil running down it since i got it.

I removed the inlet manifold (holy crap is that filthy, i will have to remove it again for cleaning once uni is finished).

I found that a pipe connecting the top of the engine to the sump, (guess its a breather) had been really badly bodged previously with electricl tape, and had a massive hole in it!

I popped up to wilco thinking they would have some piping that would fit, but there answer was simply no. I have bodged it for now with some coolant pipe that has been persuaded to stretch enough to fit!

Has anyone had any expereince with this pipe and does anyone know where to obtain one? as i can not find it on citroen service!

I can see why people block off the EGR valve as the crap in the inlet manifold is unbelieveable!

I tried a third sensor on to fix the ABS problem, this time a golf one but sadly the problems persist!

Dave,

That pipe I reckon will be the turbo oil return. Normally reinforced rubber and returning around mid-block and just above the sump. There's not a lot of pressure in it, just volume, so you should be OK with a length of fuel hose of the correct internal diameter...

What does Lexia tell you about the ABS?

davetherave · Unread post by **davetherave** » 01 Jun 2010, 21:29

Cheers Jim that sounds like the pipe! I think some 25mm or 30mm fuel hose may do the trick.
The lexia said that the front driver side sensor had a fault, i have not re read the faults since its latest replacement though. I think somehow the sensor housing and reluctor ring are out of aalignment though. So this may not help!

Unread post by **CitroJim** » 01 Jun 2010, 21:34

Indeed, the tip of the sensor has to be pretty close to the ring to work.

Mind you, the light should go out on initial ignition on/Lexia reset if the resistance of the sensor is OK even if it is not close enough to work properly on the move.

The light does go off and stays off, it only comes on irregularly. The dodgy brake symptoms occur as before, at low speeds.
