Suspension Fault warning light

I'm by Colmar in France with the caravan slowly making our way back to the Tunnel crossing on the 18th. For the passed 10 days or so, I've occasionally been getting the yellow Suspension Fault warning light come on. Twice the light has subsequently gone red. I haven't detected any issues with the suspension. Everything seems normal. We're due to move tomorrow up to Luxembourg and the next day to Domburg in the Netherlands, where we'll stay until Thursday before stopping for 3 nights on the Belgian coast, prior to making our way to the Tunnel.
What's everyone's thoughts on whether we might manage to do this without any taking any action?

This happened to me over a period of weeks - it ultimately resulted in warnings of suspension lowered and not to exceed 30mph.

However a switch off / on would reset it.

The problem (for me) was wet desiccant in the compressor dryer - depending on what kit you've access to it's an hour's work to drop the compressor and dry the desiccant in a microwave - or at least it is with an Hitachi model.

Whether it's ok to drive / tow with depends on circumstance - but mine lowered to the bump stops on the red light and was pretty undriveable

Mine's a Sept 2007, model year 2008 HSE. Would anyone know which compressor I have?

Do you have a fault code reader with you?

The specific code for my fault was C1A13-64.

Another thing to check is the multi plug at the rear of the wheel arch on the OSF. It's a three block multi plug that gets a fair battering by the elements .

With the wheel off it's easy to get to although you will have to remove trim

There could be a corroded / broken wire

Checking the codes could help narrow things down.

If the car isn’t dropping to the bump stops when the light is coming on, then you should have hope in getting home.

Cheers guys. No, not dropping at all. I just got from Colmar to Domburg in the Netherlands, over 500 kms with no issues. Unfortunately tailgate lower actuator has now failed, so something else to sort out when I get back. Will read up on servicing compressors incluing changing air drying material, checking for leaks and checking wiring for when I return as it would be prudent to make sure everything is in good order.

Been back from holiday a month now and done over 500 miles with no issues. Fault hasn't re-occurred since when I was in France.

In case anyone has any ideas, here are my fault codes:
C1A13-64 Pressure does not decrease when venting Gallery- signal plausibility failure
C1A29-92 Switch activation too long - performance or incorrect operation
U0421-94 invalid date received from ride level control module
U0123-87 lost communication with ride level module
