code u3000-55 r comes up with this on my range rover sport 2010 controll module where and what do i need to do please

Does this code come up repeatedly? Is there anything else coming up on the error codes? Are there any lights on the dash? Is anything suddenly not working?

It's a code that is used for a configuration issue on a number of different modules. But it might just be that there was a glitch once meaning the module looked incorrect once and the code was recorded in the system. If it's a one-off record then I'd just wait and see if it comes back again. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Have you had any work done on the vehicle recently, like possibly had some module replaced with a s/h one or changed a setting in the CCF files?

Cheers
Col
