Restricted performance intermittent - clears after restart
I had a spate of the restricted performance message coming up a little while ago with a few other errors (gearbox fault), and this all seemed to be related to a weak battery. Since replacing the battery, I haven't had the error, until yesterday.
When fitting the new battery, I did reset the BMS, which I believe will perform a discharge cycle to 75%. When reading codes this morning, I noticed that while the engine was running, the IID tool was only reading 12/12.2V.
Reading faults I didn't get anything relating to the restricted performance message, but enabling one of the options on the advanced tab (pending and one other, can't remember what I selected now!) I got the following messages:

I am wondering if it is battery related still, but the intercooler pipe adaptor had blown off previously. I am yet to check it but I am wondering if it has come loose again? I also noticed a small wear mark on the intercooler hose near the radiator. I don't think it has gone through, but could this be a possible cause as well?
Edit: It also appears the Timed Climate button is now greyed out!

You are right in assuming that 12.2 is inadequate.
I would charge the battery whilst not connected to the vehicle to 100%, then attach to vehicle and reset bms.2015 LR4 HSE Lux Aintree Green

I believe I have located the issue, hopefully.
The 90 bend on the intercooler hose had popped off again and on inspection the O ring has been deformed. However, when refitting it, I noticed it still did not seat correctly. It turns out, the hose clip on the coolant pipe next to the elbow was fouling on the housing. This has potentially meant that it has not seated correctly all the time it has been in that position. I rotated the clip round and the body of the elbow is now perpendicular to the throttle body!
Time to order an o-ring and replace.
Battery was recharged and fitted. This seems to have improved the voltage.2016 Discovery 4 HSE
