Had this appear on the dashboard today. Drove on the motorway with it on for about an hour and all seemed normal.

Not had a chance to read the error codes yet, but what is the usual solution for this?

The usual solution is to read the codes first to see whats causing the warning to come on...

Also, does it re-appear if you switch off and leave it for half an hour then restart? Robin

The error was on all day yesterday even though I left the car for a few hours between starting.

However I started it this morning and the error has gone. I'm sure it will be back though

The reason I ask is that I occasionally get an error message regarding suspension or special programs. It doesn't seem to affect handling for day to day road trips. And if I leave it the error does not re-appear for a while. The best theory I have had is that you shouldn't turn on the ignition and then try to start it. Count to 5 then start. This seems to reduce the incidence of the error.

Of course the best thing to do is to get the codes read as previously said but in the past no codes have been stored for me Robin

Got the codes read today and there is no error codes stored. I didn't know its possible to have an error appear but have no codes stored.

I'll try your advice in the future when it comes back. Are you saying turn on the ignition, wait 5 secods and then start the car?

Yes. That’s it. My theory (totally unproven) is that it doesn’t like being started until it’s had a chance to get all the electrics fires up. So ignition on, wait till the display shows it’s done it’s self checking thing (about 5 seconds) Then you can start. I’ll be interested to know if it improves it for you. Robin

does it have ACE? if so is the fluid running low

It has ACE. The fluid level is slighly above maximum. It hasn't happened since

This error appeared again today. Still no error codes stored and ACE fluid is at the maximum line.

Any ideas what this could be?

Need the fault codes read first..

As above, I've had the fault codes read and there isn't any stored

What diag system did they use?
You may need something LR specific as some tools can't read all the systems properly.

Took your advice and tried with a different reader today and got the following codes:
C1B11 - Pressure Control Valve
C1B03 - Direction Control Value

I reset the codes and started the car again and only C1B03 appeared the second time.
