Hi guys,

On Saturday evening I filled up my Range Rover velar, 67 plate with fuel and the fuel gauge did not move, this was the start of my problems.

Continuing on my journey and almost every warning light came on the control panel with high rpm ( like it’s not changing gear) and the speedometer not working at all.

A Range Rover specialist has checked the battery and alternator, both of which are working as they should be. I’m wondering if anyone can shed some light on what might be the situation here as the specialist has said it could be hard and costly to diagnose.

I’m not mechanic so thanks in advance.

Hi

personally would first get the codes read to see if there are any fault codes , assume both batteries have been checked as I assume it has the stop start system, along with all the earths that are throughout the body etc

hope That helps
 
Hi,

The specialist plugged the car into the diagnostics machine and it came up with 89 communication faults. From there they said they can book in for further investigation at £120 ph but didn’t know where or what they would investigate next. Already paid £120 for the luxury of knowing the above although it was clear from the control panel.

From what I saw, they only tested the battery in the boot along with the alternator at the same time, both of which were fine.
 
Find another 'specialist'. Did you request they test the battery & charging system or was that the diagnostic check they suggested?
Like it or not, it's going to cost - it's communication errors that will need a combination of wiring checks and intensive diagnostic checks of gateway modules. Quite often, although the number of DTC's ('fault codes') set can be daunting, they will mostly point to one module or gateway - which usually reports no DTC's, that is the place to start, it's not a quick process and needs somewhere that understands and can work through the network topologies, so factor in 3-4 hours to get to the nub of the issue, then the cost of the fix - it may be a 20 minute harness repair or a £500 module with 2 hours to program & code, either way, your vehicle is useless without it being fixed, so find somewhere that has the skills and warm up your credit card...
 
Most comms errors will be created when the car powers up modules when turning the ignition on. Most will be historic and of little concern. Make a note if them then clear them, and see what new codes appear. If you can't find an independent garage you can trust then put it into a main dealer. They know these vehicles best and have experience of them going wring.

I suggest buying your own LR full systems code reader, which can be had for about £120. The Icarsoft I930 will read every module, giving codes and descriptions for LR vehicles, and if the destination isn't in the database, then there's a full list of codes in my signature.
