Strange goings on HDC, Epc, other lights, and bits
When i was at JGS4x4 they did my fluids, and a remap. He checked codes before and said there was a MAF sensor low voltage fault, cleared it, and tested and all was ok.
Now today i went to tesco about 2 miles away, to collect something. On the return journey, i had the i symbol come up, and it said engine systems fault, but no check engine light, no limp mode or anything changed.
Got it home and plugged my OBD scanner in. That didnt work, as it seems it doesnt read Landrovers protocol, however, something then happened.
I got the yellow Epc light on, and the red one flashing, even with ign off.
Then i got HDC fault, then systems fault, systems not accessible, i tried using the epc pushed it up and down a few times, then a yellow wwrning trialgle ( i THINK it was the anti skid light) yet the car still started and run fine. Switching off and leaving made no difference.
After reading about a Hard Reset (meant to be going to Malvern in the morning!) i did just that (not easy for a disabled person on his own i may add!)
Once done, car started, no dash lights on, all seems ok. Epc lights all off, no hdc fault, so i went a drove it again.
Drove it 15 miles, with no faults at all, and its dark so all the lights are on.
I have checked :
-Battery with a volt meter, showing 12.2 volts, havent got a drop tester so not sure if battery is 💯
- brake lights which all work fine
- reverse lights, all ok
- brake light switch is working fine as far as i know.
So im wondering if the battery could be at fault, or wether i gave it a -fit with my £5 obd tester! 😵😵
And wether the Maf sensor is faulty.
Im not expecting anyone to diagnose on here, just wondering what others thoughts are on this.
Thanks

Yes, thats base battery volts, not engine running.
I also went outside last night and pulled the MAP sensor, which was very dirty, and cleaned it out.
Ive done a run today of 250 miles, and no major fault errors, and i managed to tickle 32 mpg on the M5 at 70mph.
The only dash warning i got was low coolant level, however, i checked and it was fine.
The drive back, the i message was gone, and hasnt come back up.
Im wondering if it is the battery playing around.
