hi guys ,
had a 2006 rangerover sport tdv6 since last year .
all been fine until past week the car has been throwing a number of faults up !
randomly will be driving alone and 3 thing have been happening
fault on dash shows up .. 'suspension fault vehicle lean when cornering" ( goes off after restart and is fine)
at the same time central locking locks and unlockes whilst driving ,
then I get a message on cd player screen "vehicle fault system shutting down" system shuts down knocks all radio/satnav off then restarts and is ok !
today I had like a headlamp icon show up when I went to start it and it wouldn't start , turned ignition off and on a few times and it started fine ,

I checked that battery and it was ok as it was only a year old ( was a cheap battery that the other person had fitted so I change it the other day for a yuasa but the problem keeps happening every day,

had it code read and cleared the re read after the car did the same thing again so I had a fresh set of codes t work from ,

her are the many codes its showing

uo140 lost communication with body control module
u0300 internal control module software incompatibility
audio front control interface module
u0010 medium speed can communication bus
u0300 internal control module software incompatibility
u2003 fibre optic communincation bus
park assist
u0155 lost communication with instrument cluster control module
parking brake
c1a55 ignition switch imput circuit
steering angle sensor module
u0122 lost communication with vehiche dynamics module
u0010 medium speed can communication bus
u0001 high speed can communication bus
u0102 lost communication with transfer case module
u0132 lost communication with ride level control module
u0182 lost communication with front lighting control module
u0159 lost control with parking assist control module
u0184lost communication with audio unit
dynamic response module
u0155lost comminucation with instrument cluster control module
ride level control module
u0434 invalid data received from dynamic response module
instrument pack
transfer case
u0155 lost communication with instrument cluster control module

im used to a discovery td5 not the rangerovers so all new to me , I was thinking maybe a bad earth somewhere ?
I fitted a dedicated brink towbar wiring kit about 2 weeks ago but cars been fine up to now ,

any help would be very much appreciated

You can ignore u codes unless something isn’t working

Sounds like a can bus fault.
They are twisted yellow wires.

Have a look under the back end of the car , passenger side wheel.
Following wiring and ensure it’s not rubbing on things. Or dammaged near connectors.

if not a wiring issue as suggested then it looks similar to an issue I had earlier this year - all modules were not communicating with one another ( 2 x A4 pages of same and more fault codes) but the fault was with the instrument cluster. Put a new one in and everything ok thus far....fingers crossed

I didn't do the work myself - the car was in the main dealers for weeks and the useless idiots there couldn't even do it so a couple of technicians had to come directly from LR to do it.
I don't believe swapping the cluster is that difficult a job but you must have the CCF ( car configuration files) downloaded to the new unit otherwise everything would still not be communicating.

ah ! silly me thinking something involving landrover would be straightforward !

That's why we own them isn't it?

If/when it does it again, hit the top of the instrument binnacle and see what happens. 2019 5.0 SC SVA (Current)
