That makes it about 1500 psi Kev

Now that's some boost!!!!

have a natter with Xac about boost gauges... His is very neat and easy to plumb in.

Dave, I'm sure you must have a boost leak. That'll be why it's whistling...

i Agree with Jim, no go and a whistling noise is ayour boost making for the sky.

Kev, looks like that xm will be perfect in no time by the time you have finished all those jobs

Hope it will be appearing at the Ds rally kev!
I think i have a hole in the intercooler, sadly that involves taking the front end off!

only slightly Dave a little lean of the nose is enough, got a good intercooler here if you want it, i need it gone really.

Dave, A boost leak and the fact its an auto (which does seem to sap power according to the Xms specs) might be the reason.

Ah yes, that will have to be one of this years topics in the series of "Xac...WHAT are you doing to my car?!"

IIRC last year was:

Get it right first time (without breaking anything): Xantia door cards
XUD Bosch injection pumps: Tweaking - Level 1

So that means boost gauges will be covered in:
XUD Bosch injection pumps: Tweaking - Level 2

Cheers Dean

Unfortunately Dave, I think that the Xantia will be making an appearance at the DSM. I've got to build up the anticipation somehow

You'll also need a T to take off the boost pipe that goes to the UFO and a few jubilee clips.
The gauge needed some tape around it's rear to hold it in the pod.
The boost sensor sits behind the OS strut top, cable tied to the sphere's pipe to keep it neat.
It's black wire goes to one of the wing's bolts for earth, I've extended the red wire to run along the front of the engine bay to the battery.
The white signal wire goes through a gromet used by the scuttle, if you flex the scuttle out the way with a flat screwdriver, there's enough room to grab the end of the wire once you've fed it through the gromet, with a pair of long nosed pliers.
This then goes down the back of the top edge of the wing by the door, and out by the top hinge. I've fitted paddle connectors so I can remove it easily.

The wires from the gauge run down the side of the dash, the green signal wire goes out by the door hinge to connect to the white signal wire.
The yellow wire goes to the dimmer switch, I think the orange wire there rather than the yellow, I just nipped the wire coating and wrapped the yellow around it.
The red wire needs to go to an ignition feed, but I've not got around to sorting it out, so it too comes off the dimmer switch meaning the gauge only comes on when the lights are on.
Eventually I'll wire in spurs with paddle connectors (female and shielded) so the gauge can be removed if needed.

No more pump tweaking, next it's turbo tweaking

Thats a good little list of jobs there, many of which are similar to issues I had on mine.
For the washer jets after repeatedly unblocking them I took the entire resevoir out from the nearside front wing, bit fiddly but can be done. Then cleaned the tank and cleaned the pipes with pipe cleaners or similar. It was amazing to see the amount of crud that gathers!

The Dot matrix display is another job that i found to be trial and eror and much frustration, but not too difficut.

I cheated and got someone else to do the cambet for me

as I was too scared!

Bits to do:

Replace dash bulbs - Airbag light is out

the one I noticed was out was the green dipped beam bulb

I am preparing my smart roadster for its MoT tomorrow and after a winter of two XMs I had forgotten just how much fun it is - mind you the white XM is in the garage too - with a (lack of) fuelling issue.

red_dwarfers · Unread post by **red_dwarfers** » 20 Apr 2011, 22:37

Cheers Campbell, I didn't notice that

Hope its nothing too bad on the fuelling front, are you sure there's diesel in the tank

Yesterday I made a start on the cambelt. The layout is near as dammit the same as the XUD9 with a few small changes which make the job easier. The auto tensioner for example, none of this plunger business just wind back using a 10mm socket and do up the other bolt. I'm glad I decided to change the water pump as there is evidence of it leaking a small amount along with play in the bearings.

Today due to other stuff going on and overrunning, I haven't got as much as I'd like done to the XM. Went into GSF to pick up the cambelt and tensioner kit, waterpump and two accumulators. I also stopped by the Citroen dealer to pick up a couple of seals for the hydraulic pump and one for the rear accumulator.
The guy that was serving me at the parts counter was obviously a bit green when it came to hydraulics so he went and got the old school guy who knew exactly what I was talking about. After a good natter about parts availability for the older cars (apparantly I was lucky to be able to get those seals as theres only a few left on the shelf

) I handed over an extortionate amount of money for a small envolope containing three seals. Still, it had to be done...

Propped up the engine before removing the right hand engine mount and did read to see what the XM BoL had to say about any best practices when removing it. No amount of rereading made me understand what on earth they where on about, I had a look at the Xantia BoL for the 2.1, that was crystal clear and matched up with the XM much better!
Also flushed through the engine and radiator and the pump is now resealed after snapping the old ones off.

The XM is almost all back together now, just need to fill up and bleed the coolant.
I ended up taking a bit longer than originally anticipated as I soon realised that there was no rush to get it back together what with it not being a daily driver.
No real issues, it was a bit of a 3D jigsaw puzzle at times, the engine side of the engine mount and the hydraulic pump come to mind here. The flywheel timing hole is in the same place as the XUD9, an absolute nightmare trying to find it for the first time but something to impress all your mates with after that!

Just been reading through your thread Kev, congrats on the XM

I do prefer the look of the XM as a big saloon and its not often you find a clean one nice and straight.

It will be interesting to see how the project goes.....are you going to keep both when its done?

red_dwarfers · Unread post by **red_dwarfers** » 01 May 2011, 12:15

Just been reading back through and I seemed to have missed your post, sorry

That would be a good idea, here they are:

Dave, the cam belt isn't too bad a job. I can think of much worse namely wishbone bushes

I think I may give the turbo mods a miss for the time being, though I am intrigued at how much difference there is in performance when I next see Cassy. You'll have to take me for a ride.

Upping the boost wont hurt it at all Kev, and it will give it that little extra ooomph
