These are the faults gents how doni resolve

I see battery voltage at 13.3 and 13.5V to low for the engine speed, should be 14.1 to 14.3V
Last photo 11.4V at idle, just how old is the battery again should be running 14V at idle unless you are lighting the neighborhood.
Possible voltage regulator?? alternator, or battery
does the car struggle to start?

I had just replaced the battery in December then had my voltage regulator repaired in January i assume that something might be wrong with the regulator , now that u mention this my ESP module has an internal fault coming up could this also be caused by poor voltage?

Not jumping to any conclusions but recheck the battery and electrical system, voltage is very important in these power hogs.
If you are not getting 14.1V when idling this is where I would start WHY??
battery voltage when car has sat overnight- 12.6V- turn on the lights see just what the voltage drop is, maybe a bad cell in the battery, but I would say alternator check is necessary
running 14.1V not 11.4 you have on photo 3

I am wondering how far further down it will go - say 10V? - before the thing has no chance to start even if it cranks. I admit I have no factual info - or alternative facts for that matter - but I have had cars that would crank and not start because the system protects the electronics from gremlins that creep in at low voltages.

There definitely is a protection threshold and not at low as 10 and I don't think the ECU would even let it crank.
As far as voltage, if battery is replaced and regulator too, checg grounding and even add some.

At probably 12V the car may turn over- May Turn Over- with a lot of effort but not start
Did you use an AGM battery or standard acid/water wet cell found in most other cars
At 10V the lights may glow but that is all beside the red battery warning indicator showing on the dash.


Static battery voltage should be above 12.5V with no accessories on- overnight-checked in morning
