Hi all i'm looking for some help locating a problem ive got.
I have a P reg Xantia 1.9TD non active suspension with 130,000 miles on the clock.
I purchased her 3 years ago from a citroen agent with 80,000 on the clock - from go i had a load of probs with the suspension and they ended up replace all the spheres and most of the valves on it.
It's been trouble free since but recently when its been left for a while say over night or morning till dinner the Stop light stays on the dash for 15 seconds - sad i know cos i timed it!
If i try to drive off, say reverse off the drive then brake, before this light has gone out there is virtually no foot brake.
If i wait for the light to go out it's fine.
Other than that the ride seems fine.
Any ideas would be appreciated.
Thanks in advance
Mark

Yep, I've had exactly the same problem on my car. It's also a 1.9TD 'R' Reg Temptation with non-active suspension and about 160,000 on the clock.
Question: have you also noticed strange steering problems with the car when cold?
I ask this because I suspect the hydraulic pump (advice given to me from earlier posts on this forum this week), and hope this will also solve my 'lazy' Stop light a make it go out after just a few seconds like it used to do.
I'm no expert, but I am getting ready to change my hyraulic pump based upon the various advice' received.
Good luck,
Steve

I have a similar problem with one of my Xantias. It takes at least 15 seconds for the hydraulic pressure to come fully on in the Summer and anything up to 10 minutes on a cold Winter morning! It's always been this way. I've had the system flushed to little effect. I Citroen mechanic told me that some cars are "just this way". Has anyone got an explanation or solution?

I'm sure that a Hrydraflush and change of LHM/clean filter etc would solve the problem... these pumps should last a lot longer than suggested (except the plastic ones).

In that case you had better find another Citroen "mechanic"kevin1962 wrote:I have a similar problem with one of my Xantias.

Some cars are not "just this way", 10 minutes is a definate fault....(boy I hear some drivel out of the mouths of so called experts sometimes no wonder Citroen's can get a bad name...)
Taking a long time before starting to pump the system up like that is a classic case of the pump losing its prime, so check the hose from the tank to the pump for integrity, make sure there are no cracks, that both ends are clamped tightly etc.
There is a small chance it could be the pump as well, but definately check the hose first.
Also you could connect a piece of clear hose in line with the return pipe to the tank as I described in this thread: (including picture)

Then in the morning try slackening the pressure regulator bleed screw and starting the engine then watch the hose, if all is well clear oil should flow immediately.
If the pump had lost its prime the oil will barely flow at first and then suddenly it will come wooshing through with massive amounts of air, then gradually clear itself. (If the leak is bad there will always be a little bit of air though)
If you see something like that, its a sure sign of a suction leak causing the pump to lose its prime.
The type of pump used is very poor at self priming, as it relies on the oil film inside the cylinders to seal the pistons - no oil on the inlet, no oil film, so poor sealing and very little pumping. (Eg it can't pump air very effectively)
All it takes is a moderate air leak on the inlet hose and it will really struggle to prime itself. Additionally, the pump finds it much more difficult to prime when it is operating into a load - eg trying to pump up the accumulator sphere and the rest of the system.
Opening the pressure regulator bleed screw in this situation removes the load from the pump and makes priming easier. You'd probably find that on one of these cold mornings where it refuses to lift, if you opened the bleed screw for 30 seconds or so with the engine idling and closed it again the car would then lift, as you're helping it to prime faster. Again, a sure sign of an air leak if this helps.

Simon

At least one good bit of news came out of all this, the original garage replaced all the spheres and most of the valves, hopefully for FREE? if indeed free, thats a rare thing to behold.
10 minutes for the STOP light to go out is a fault as Mandrake says, time now to start getting to the bottom of the problem.

Well,
1) Ive changed LHM and bled it though.
2) checked the suction hose - this seems to be in good condition.
And come to the conclusion that the accumulator sphere is ok as im not getting any clicking from the pressure reg valve.
So im looking at a lazy pump? Looks like ill live with it the way it is then
