Do the simple things first.
1. Clean the TWO filters in the LHM reservoir.
2. Check that the pipe from the LHM reservoir to the pump isn't leaking air in at the connection on top of the reservoir (the pump is sucking LHM through the inlet filter).
These two things are linked. When the LHM is col, the pump has to suck harder (greater negative pressure). If the filter is dirty, the pump has to suck harder. The harder the pump has to suck, the more likely it is that air will get sucked in at the connection on top of the reservoir.
The problem with the crankshaft pulley is that it is made of three parts: 1. the steel inner (bolted and keyed to the crank shaft); 2. the grooved steel outer ring that drives the belt; 3. a rubber damping ring that is bonded to 1 and 2 and thus transfers the drive from the crankshaft to the belt. With time, heat and miles, the bond eventually breaks so that under high load, the outer slips relative to the inner. Once this starts to happen, it's not long before the pulley fails completely!
I hope this helps

Ok thank you!! I'll follow your indications!! if theres any new I'll write it!!
Re: Xantia Steering wheel hard when cold
Hi Old Guy!!
Bad and Good news. Good because I made the mark on the crank pulley with the engine very cold as usual. then I started it and made some steering quickly and I felt the usual hardness on cold . Then I checked the pulley again and the mark was straight. It seems the pulley is ok but I'll recheck it on a week. This time the stop and caution lights showed up again after 8 - 10 minutes of driving. When this happens I can't hear the pump but some (1-2) minutes later the lights go off. The steering progressively softens as it warms.
I made some citaerobics and there wasn't bubbles in the tank. Making this operations the engine heats up and makes everything back to normal.
Bad news because I can't see the light with this problem yet!!

Re: Xantia Steering wheel hard when cold
Did you check filters as Old-guy suggested?
Here you see a clean filter and a dirty one. Quite obvious.

Re: Xantia Steering wheel hard when cold
On the XMs with a 'V' belt drive it was nearly always the belt slipping, if yours has a ribbed belt its not so likely but worth checking.
