Hi Guys
Just returned after my 2013 L405 annual service where the Indy garage reported that two faults linking to both sides of the vehicle had been thrown up by their OBD reader during the service reset process. U0233 was the fault codes.
Checked on the web and on here can’t find any real information- anyone have any ideas please.
Thanks.

Usually caused by low voltage to the rear RADAR sensors, this can be during cranking if the starter battery is depleted, ideally you'd need to know the frequency of the DTC being set to determine if it's a recurrent fault or sporadic/one-off, if it's recurrent, then it'd be worth checking the connectors on the units behind the rear bumper for water ingress & corrosion.

ETA - just re-read the thread title, I assume you're not referring to the park system of the camera module?

Thanks for that. I have just found out that as I don’t have the rear radar fitted to my vehicle. There is a recent Land Rover bulletin which states in that event the codes can be ignored!!!
