I can hear the supercharger auxiliary electric pump turning ON when I open or close the driver door. Looks... -

Bad ECM or something else?
I agree with your statement, but then why does the t-stat have an electric heat element? I will troubleshoot further. I vacuum filled the coolant, but still have air pockets in the front cross over pipe. -

Bad ECM or something else?
On Guam we have limited mechanics familiar with European cars. I have taken the LR4 to two different mechanics. One said it is an engine internal issue. The other mechanic shop has no idea. I don't trust the Land rover dealership. -

Bad ECM or something else?
At idle, coolant temp is normal for about 45 minutes, then overheating rapidely. I can't monitor actual temperatures of ECT1 and ECT2 because no communications via the OBD socket . -

Bad ECM or something else?
I suspect a faulty ECM on my 2015 LR4. I have the following symptoms: Overheating. I suspect the ECM is not energising the electric thermostat. The upper radiator hose is never hot. Viscous fan is always engaged. No communication with the OBD socket. See attached picture. I have confirmed 12... -

Auxiliary Battery
My auxiliary battery is dead on my 2015 LR4. The eco start/off light is ON. I don't mind not having the eco start/stop function. I never use it. What else does this battery do? Do i need to replace it? Can the LR4 do without it? -

Throttle body coolant line mystery
