Affecting: Saxo 106
Increasingly popular is the gradual or not so gradual deterioration of power steering. With the electrical pumps fitted to various Citroens and Peugeots giving up the ghost, common symptoms are intermittant heavy steering or permanent loss of power steering. (A bit hairy on roundabouts!). The system is protected by a fuse in the fuse box. This is of course your first port of call. Secondly, check the control relay. Early versions have a relief relay with a round multi-block connexion. Later versions have a standard looking relay. Both should be less than the price of a pint. If the relay tests out OK, then you are almost surely looking for a new pump.
