The legacy of the dreaded 'Economy Mode' is still with us and likely to stay, albeit in a new guise.

On the C5 X7, and on many other PSA vehicles a 'Battery Charge Status Unit' (BCSU) is fitted to the negative battery lead.

For those that want to know what it does: - simplified
The role and function of the BCSU is to calculate the battery...

If your accelerator pedal is suffering from the 'droops', here's where you need to adjust it:

The accelerator cable has a fair bit of travel from the pedal to the throttle potentiometer and over time, you may find the pedal drops an inch or so. This of course will lead to reduced performance as there is too much slack.
The throttle sensor is...

Hi All
It's been a while since I was on the forum but I could do with a bit of help. My 2009 C5 Tourer has failed its MOT as the handbrake is not doing its job properly.

The cable at the caliper end seems to be sticking too far out so when the unit engages there is insufficient pull.

The options discussed with me by the garage are to either...

Here's a couple of things I've cobbled together that may / may not be of any use, but useful for reference purposes if nothing else!

First thing of note is a few lines concerning disconnection of the battery in relation to Tourer models with the motorised tailgate:
It's probably worth a mention regarding the BSI reset procedure if anyone has the...

My wife's 2.2HDI C5 Mk1 2004 Exclusive Automatic gave the diesel additive warning a few thousand miles before 100k.
We continued to drive it for well over a thousand miles before I finally tackled it. I was armed with a Eolys refill kit and 1 litre of Eolys 176 (green).

You read posts that suggest that the Eolys additive is not being added as...

Up for your delectation today, we have a CUSTOM designed and made replacement for the Power Assisted Steering Hose on the Citroen Xantia.

I purchased the car, knowing it needed work. The previous owner had been quoted in the region of £500, 2 days, and that wasn't a guaranteed fix either. It took a few £££'s to get it right, and arguing with the...

As discussed:

Rather than break the thread or shift it, here's a link to a thread in the Citroen forum regarding testing when the ABS warning light stays on. It also includes pin outs for the test.

Thanks again to those who have contributed.

I was getting a new muffler on one of the cars the other day and whilst there found a brochure relating to the topics of this post.
It was a re-run of an article attributed to NRMA Tech Topics Bulletin 1/98 and whilst it's long & involved, I'll try to summarise it here as it may answer a lot of questions associated with the problems we get on...

I've got a bit of a rattle from my air con compressor, only when the air-con is off, it disappears completely when I turn the air con on. I thought I'd better fix it before the pulley drops off!

I'm guessing that the idle bearings in the pulley are dead or dying and need replacing. I've got a Sanden manual that suggests the pulley is easy enough...

From a previous posting which offers a solution to the mad ticking that some Xantias get that seems to eminate from the steering wheel area.

With thanks to member deian for his efforts on this.

To use, click on thumbnail of pic you wish to see. When enlarged, this will bring up a series of boxes in some photos. When the cursor is run over the inset boxes, a description of the part will pop up.
Handy when trying to identify parts when doing repairs.

This week I've had my first opportunity to take a decent look at and become a little educated on the ZF auto in these cars.
It has always been said that the ZF auto was considered bomb proof in the CX yet in the lighter BX it has had all kinds on things said against it; granted not the same box, but rarely does a manufacturer go from a quality...

Our acknowledgements to peteev for the excellent detailed description of the job detailed below.

Here's a link to a (long) detailed write up on the fitting of air/con to a series one BX16V.
The things we learnt along the way can be used as a guide to anyone retro fitting air/con to any make or model as a lot of the traps are universal.
It should be remembered also, that by trade I am a refrigeration and air conditioning mechanic with many...

If you've ever replaced an accessory belt on a BX with air/con, you'd know the high pitched squealing that usually follows this, caused by belt slip.
It is particularly common on 16Vs and it usually ends with someone declaring it's a faulty belt or something else has gone amiss. Here's the procedure that should sort it out.
Slacken the top bolt on...

Just did the injectors over on the TZi but the same applies to the 16V.
Kits are available (includes enough gear to do 2 nozzles) which cost around $10.50 a set, so for about $21 and say an hours time, a full revamp of the injectors can be done. This includes filters to fit in the nozzles, O rings and end caps and makes one real big difference to...

Had to do a rush job on a BX that came from the UK.
A rear wheel bearing had collapsed following the seal backing having rusted out due to salt contamination. This of course caused the seal to totally collapse and leave the bearing open to a variety of foreign substances such as moisture and grit.
The result was that the inner cone had become...

O.K. I admit it; I'm cheating here, but I asked a question on a board and then answered it myself, so I'll do this in two parts; ask the question (just like most do when they look at what seems to be a Mission Impossible ) and then I'll give a detailed answer.
I'll try to edit out some superfluos banter if possible without losing the content....

The bane of every BX owners life seems to have been these rear (swing) arm bearings. Few have mamanged ownership over any amount of time without having to do them, some more than once.
The symptoms: When the car is set at its highest suspension position, the rear wheels when viewed from about 20 feet away look like this / \ or ! \.
Creaking...

After putting up with the green drips on the driveway whenever the car was parked long enough to allow the suspension to settle, it was decided when the clutch cable carked it that now was as good a time as any to fit the seal kit to the steering pinion.
An examination showed that the problem extended further than the seals too with the steering...

As these pipes already contain LHM I don't see how the ride can be improved, unless of course it's feature of new LHM like the short lived non-sinking rear end when the LHM is replaced.

Here's a copy of a posting I've put on an Australian Citroen site (mainly because BXs are still fairly *new* by our standards) but one I feel could also be of interest to any Cit & possibly some Peugeot owners. It concerns the lazy starter syndrome and a cure for it.

Before you start, disconnect the speedo cable under the bonnet at the junction of the upper & lower speedo cables to confirm whether it is the upper or lower cable that is broken.
In most cases it seems the upper cable (the top one) is the most likely culprit.

To access: Remove the tray near the...

Here's a tip that I have found useful when assembling/dis-assembling brake
pipes and unions.
Before tightening up a rigid brake pipe union, carefully smear a small amount
of copper based anti-seize compound around the brake pipe BEHIND the flare. I
have found that this stops the sort of corrosion that can seize the union to
the pipe and thus...

As many know, a while back my son did a rebuild on the BX 16V series one (160 BHP) engine. Everything was done by the book & only the best of the best went into that engine & only very competant tradepeople worked on or oversaw what was done. It should have been as close to perfect it was humanly possible to get!!
On completion, it was even given...

Below is a copy of a posting from one of our members LHMleak about an incident that happened to him recently in his Xantia with anti-sink.
As a BX & CX driver, I would never have thought of this just as he didn't; red light comes on indicating low LHM, not far to go, car stays up so it should still have brakes & steering is exactly what I would...

A thread on this subject complete with pics that should be of help to all those Xantia owners who have gone beserk in the past rying to solve this one.

We often get requests on the forums for advice relating to why certain cars radiators or the heater matrix seems to be continuosly rotting holes in themselves.
It has been blamed on the salted roads in winter causing corrosion from the outside in and in some cases this is possibly a reasonable explanation, however, even that problem can be...

This has been taken (on the authors authority) from another board.
It related to a job done by this guy & using Gerry, a Morgan rebuilder as a mentor & assistant when doing the job.
It was done on the head of an 8 valve BX Gti, however, the principles used would be applicable to other engines in the range.

We often get postings from people having problems loosening parts that have corroded in and predictably, these all too often all end up in tears when something like a brake bleed nipple sheers off in the caliper or a rear sphere is so tight that the rear cylinder turns & takes out all the plumbing in the process. As a former tradesman working on...

Some information of the wiring of door locks (with deadlock facility).
The electrical connector has 5 pins. Call the highest pin No.1.

Uses pins 1 and 2. The resistance across pins 1 and 2 should be about 5ohms if the coil is OK.
If OK, applying 12V+ to pin 1 and negative to pin No.2 will unlock....
