L494 2014 Diesel Hybrid - Hybrid System and A/C Temp Unavail

Morning all. I'm at my wits end. I had the dreaded Amber error "Hybrid System and A/C Temporarily Unavailable" followed by the Red warning "Range Reduced" which eventually renders the RRS undrivebale.
I went down the route of getting the hybrid battery repair carried out at a cost of >£6K. The battery repair was successful but the amber warning "Hybrid System and A/C Temp Unavail" remains. I've had it in at an independant LandRover Specialist and they were unable to identify why the error remains. I'm after the part number of the electric power inverter converter for this vehicle. Does anyone know it or know how to resolve the nightmare I'm currently enduring?

Regards,

Sean

Hi Sean,
Where did you end up with this?
I've just bought a MY16 version and feeling very nervous about the whole thing now....it seems to drive ok but nothing works as the manual says it should eg start/stop doesn't and it doesn't work on electric alone....

Keen to hear where you got the battery fixed and what they did - did they actually replace the cells or just recon the plates and BCM?

Cheers.

Here's the catalogue page for the EPIC

I'm pretty sure that I've read if AC and hybrid system is unavilable it's usually the HV heater unit

Have a go with the search function, I'm sure it's not uncommon!

Certainly on the later P400e cars the HV fails in most cars at some point.
Could be the problem? 2026 P460e Autobiography on order

2022 HSE Dynamic P400e

2017 Discovery 3.0 HSE Silicon Silver Nimbus interior and a few extra toys SOLD

2013 HSE Black, Orkney Grey, Ebony Seats and Ivory Interior SOLD

Plus a few other cars inbetween!
