Improved feature for unsubscribing from email notifications

As part of the work being done to improve the deliverability of emails, I have made some changes to the system for unsubscribing from email notifications.

These changes are to ensure stricter compliance with RFC2369 and RFC8058 (which are the internet standards for such things), there are also some additions for Microsoft-specific rules which are...

Xantia 1.9TD Aux belt length for A/C bypass

You know that horrible sound, rusty metal squealing against rusty metal as the compressor's pulley bumps and grinds away with old age.
We know that if you can't replace the bearing, it eventually fails and you end up making fire - which is bad. Very bad.

If you find a hurricane howling through your aircon equipped Xantia because the blower fan is running uncontrollably at top speed, this indicates that the speed control module has failed.

Be aware that the A/C system will be shut down if any fault is detected in the engine cooling system, such as a faulty fan or speed controller, or even the thermostat heater (if fitted). You really need to get all of the fault codes read for the A/C system and the engine ECU.

Since a refrigerant recharge last summer my air con had all but lost all effectiveness and the system hissed loudly inside the cabin, the usual sign of low refrigerant charge.

Yeah, when I took mine out it pretty much disintegrated in my hands. A condenser is probably easier and cheaper than a compressor at least, if it is that.

The blower motor is probably faulty then. They do fail and this is one of the symptoms.

Last post

Make sure to go to a proper a/c capable garage. Places like Halfords just add gas to the a/c system. Specialists will evacuate and separate the original contents of the a/c system, put a vacuum test (to test for any leaks) on for twenty minutes or so, then add in the oil, U/V dye and refrigerant. The process should typically take an hour or so....

And if you don't get the system vacuumed down first, you don't know if it is leak free and it it might also have moisture still in it - which is bad news!
So, best to avoid the can refills and get it checked by a specialist, or even a fast fit re-charge place.

You may or may not be aware that there's currently a drive underway to phase out the use of R134a which most relatively recent air conditioning systems use.

The effect this has had is that it's vastly pushed the wholesale prices for the refrigerant up. This is only going to get worse.

When the system was refilled, the pressures should have been checked with the engine running, this would have immediately shown the health of the compressor.

As the original poster I thought I would just post a follow up on this thread now that it has been resurrected.

Thanks to Daniel for taking the trouble...

Alternative refrigerant pressure sensor?

by teuski » 20 Jun 2016, 05:36

First post

I need a new refrigernat pressure sensor for my '96 ph2 Safrane. I can't seem to find new ones, at least not for a reasonable price.
Since the AC system is pretty much the same in all cars, i suppose some other car's sensor would do the job if it fits physically.
I suppose the sensor operation and values are pretty much the same anyway.
Maybe...

This sensor for Dacia Duster works just fine :)

1998 Renault Megane RXE - entire air conditioning system disabled

First post

i took my vehicle to an air conditioning specialist and he said the car needs a new motor. i logged on a website for parts but couldn't find any motor , but instead had plenty of other parts available for something such as this.

the air conditioning system does not turn on at all, it is completely dead. once, it did turn on at a set of traffic...

Just to be clear, is the problem.

1. The fans don't turn on inside the car.

2. When you press the ac button nothing happens.

Refrigerant pressure sensor bypass?

by teuski » 09 May 2016, 16:43

First post

I had my '96 Safrane's aircon filled but it still doesn't work. At least there weren't any major leaks and the machine decided it was ok to refill.

The AC text appears on screen when requested, but when it's warm enough for it to start there appears service text too and the compressor never engages.

My CLIP tester gives circuit open faults on...

Last post

Try setting the system for defrost, as that should automatically bypass the water temperature sensor to narrow things down a little.

Xantia air con not as cold as it was, despite re-gas

by Jaf » 02 Apr 2016, 17:30

Hi folks. Fred had a second hand compressor Aug 2012. Since then she had a service 2014 and all has been good. With a cheapo temp gauge poked in the air it was getting down to 5 degrees.

The air is now only getting down to 10, so she had a re-gas Friday, which did not help. There was still gas in the system so if there's a leak it's small. The...

Stepper motor/ heater query

by orosurf » 08 Jan 2016, 17:58

First post

Hi folks, sorry if this has been asked before, I have been searching for days and my head hurts. The heater in my Xantia hdi with climate control/ac has suddenly started to only blow cold air. This is a big problem for me as it is -22 here in Russia. I have checked that the matrix hoses are both hot, had all the control unit out . All flaps seem...

Last post

Not sure if the problem was the stepper motor , the ecu or the control unit, but the flap was stuck, possibly frozen due to the extreme cold and condensation. I managed to get the motor out, open up the reduction gear and manually turn the cog that moves the flap, I now have heat ! Not pretty , but I don't care, at least I can drive the car to...

flashing stop light and temp light

by KennyW » 05 Dec 2015, 11:18

First post

Hi All,

Got the abovelights flashing on dash. Citrojim suggests a problem possibly with connectors , sensors etc.

Can I confirm the double fans are a similar set up to 1.9TD but what are the differences.

How do I set both fans spinning ie brwon sensor on 1.9TD pulled will cause both fans to spin at full speed.

Kenny

Hi All,

Well put 4 pin relay in and the fans are working. Left fan a bit sticky will require some lubrication.

Hi.

I´v got a Citroen C5 2002 that i´m fixing for a friend.
The aircon heater only outputs 37 degrees celcius accordning to autocom at full heat.
It´s an dual aircon, and it´s the same temperature on both ducts.
I´ve been trying to look inside at the flaps but they doesn´t look broken.
All 3 flapmotors are working, no faulty axels.

1.9TD Xantia A/C Compressor Noise

by Zelandeth » 28 Jul 2015, 18:58

First post

Made a realisation a little while ago that the rattling noise in my engine bay that I had been scratching my head about the source of for a while stops completely when the compressor is running.

My guess is that this is due to wear in the bearings in the free wheeling mechanism on the compressor pulley.

It hasn't got any worse since I got the...

Last post

Forgot to mention: on my compressor at least, the clutch bearing is not adjustable - its a preloaded double row angular contact job. Any wear at all and it will develop play.

Well, I don't know what happened to my post. So oil continue here. Thanks for the info Jim, when I checked the readings today I had batt voltage on the orange wire, regardless of the speed position.
I'll have to get the control panel out tomorrow, see if there's a loose connection.
I'm thinking/hoping, there's an open circuit. That might explain...

Aircon blower stopped -Yr 2000 HDI - help

Hi all,
My heater blower motor has been a little iffy of late and occasionally stops working. No amount of moving the fan speed control lever helps.... and then it will work merrily away of its own accord as if nothing had happened so I suspect a poor contact somewhere. I have just removed the instrument cluster to fix a sticky speedo using an...

Back to this again :? . Heater/aircon fan started playing up again. Yes the aircon switch lights up, but this happens without aircon, on fan only. Any ideas please?

Hi. I have a C5 VTR PLUS NAV HDI (2010). Air-con wasn’t working so I had it filled up about 6 weeks ago. When it was being filled I was told that ‘it held a vacuum, so it looks good’ and it did work very well when I tested it on the way home, the screen iced up etc.
The weather’s getting warmer now and to my dismay it’s not working.. I questioned...

Thank you V6 :) , or is it :cry: ??
I wonder if anyone knows as to which type leaks between the halves. Mine is Nov 2000 manufacture. Could have another go and see if I can read off the numbers if that will throw any light on it. Any one any more info?? Will any late model compressor fit? Thanks.....

XU5 to XUD Air Con Swap

I have recently acquired a 405 with an XU5 engine and icy cold air conditioning. I'll be installing an XUD lump soon, and would like to keep the AC as it seems to be working so well. I'm hoping that as they are both XU series it should be possible and hopefully not too much of a headache? The XUD never had AC originally so one thing that springs...

Aicon inhibited by injection ECU?

The aircon on my facelift C5 2.0 hdi has suddenly stopped working - the clutch does not seem to be engaging.
A Lexia session reveals no errors as such, but the injection ECU appears to be issuing an inhibit command to the aircon. Any ideas why it might do that under normal running conditions?

Greetings from God's Own County*!

On the motorway trip, the aircon was working well. Too well in fact. The outside temp gauge was showing a bracing 11 Celcius yet, despite setting the climate control to 21 Celsius, the aircon was belting out vast quantities of icy cold air. Now, being new to aircon, I'm wondering if this is normal...

Last post

My second c5 did that. It's likely either the temperature flap seized or the spindle worn or both. Most likely a dash out to fix it. One of the reasons why I did not fix my car when I bashed it and sold it on.
