Power steering fault?

[sundaydriver]

My power steering lately feels heavier than usual, i thought at first it was just me due to driving in the snow but now the snow's gone it feels even heavier and i'm down on MPG. On a usual run to work i used to get around 36MPG but now im getting on average 30-31MPG

I've checked the tyre pressure's and they seem OK (33psi all round) but i did have a flat battery a couple of weeks ago and maybe that has something to do with it.

33psi??? 

bit on the low side

33psi??? 

bit on the low side

Those tyre pressures are fine, hope you get it sorted soon.

Steve: A bit on the low side. Should be 2.6 bar or 37.7 psi. (1 bar = 14.5 psi).

Thanks Asker, will change them to the correct pressure's

yeah of course they are mate

00668 - Supply Voltage Terminal 30
00668 - Supply Voltage Terminal 30: Signal Outside Specifications
00668 - Supply Voltage Terminal 30: Implausible Signal
Possible Causes
Fuse(s) faulty
Wiring/Connectors from/to Control Module faulty
Power Supply (Battery/Generator) faulty
Possible Solutions
Check Fuse(s)
Check/Repair Wiring/Connectors from/to Control Module
Check Power Supply (Battery/Generator)
Special Notes
When found in an individual control module, it's most likely a local source (e.g. wiring/connectors).
When found in multiple control modules at the same time, it's most likely a common source (e.g. ground spot, battery, generator).
Intermittent codes are often stored during low outside temperature when the battery capacity goes down and may be ignored.

In other words prob the flat battery.
But the date and time

Why would the flat battery cause power steering problems?
And also do you think it's just a case of clearing the fault or has it caused some damage when the car was jump started?

I had so many error codes when they disconnected my battery at the bodyshop sometime ago. Now that you mention your weighty steering, I felt mine was also very heavy after the diconnection took place. Darren attended to this.

Now, I seem to have a slighty weighty steering again, since the car has been to the bodyshop. They have promised me they had not disconnected the battery.

PS: Also found idling was not as smooth.
