Xantia Suspension Problem

Iain Haddock · Post by **Iain Haddock** » 20 Jun 2004, 19:16

Problems started with heavy power steering and car slow to rise. Changed high pressure pump for a second hand unit which cured power steering. Came into some cash and fitted new pump, whilst doing so found the usual noise you get when depressurising the system did not occur. The suspension sometimes drops (not all the way), as it did before fitting new pump. Furthermore it sometimes drops when the ignition is turned on. I suspect the pressure regulator and would like to recon as detailed on the BX pages if i can obtain spares due to the cost of another new unit which may not cure my problem. Any advice would be appreciated.

Can you give us some more information please. In particular we need to know how old your car is, if possible which type of pump it has (one or two outlets, and is it fitted with the anti-sink mechanism or any form of hydractive (ie activa)
As a preliminary observation I would say that the pressure regulator itself seldom gives problems apart from the non-return valve needing re-seating. If you have one (single outlet pump before 1995) the flow diverter valve is a common culprit.

Hi Jeremy
the car is a 96, with anti sink and the pump is a twin oulet.
