Hi guys.
I'm having some issues since the pump change and could do with some pointers please. I've just bought an iCarsoft i980 to allow me to clear and read codes and values.
On turning the engine on I will usually get a red "drive carefully" with system pressure reading 4 bar. There is also an audible clicking sound coming from the left rear of the engine, passenger footwell area. After a minute or so system pressure rises to 95 bar, warning turns to white "visit workshop". Another minute or so, the clicking noise stops as system pressure climbs to 175, the warning disappears and pressure stays there while driving. Over bumpy roads the pressure varies between 165-180 bar.
I also had the ABS lamp light with an ESP & BAS warning come up, but no fault code stored. That happened once only and disappeared after 20-30 seconds.
What concerns me more is the "Stop! Car too low!" Warning that I got earlier, along with the squeak of tyre rubber on wheel well. I bumped the car up on the level adjust and that went away.
Looking at the strut level values, it seems as though front left and rear right are sitting higher than the other corners.
System voltage is reading 14.80V.
Any thoughts please chaps and chapesses?
