Hi all, so those of you who know me and my threads, probably know too much about my POS little Picanto by now, and I hate to bore everybody with my incessant prattling on and on about it...
And I realize I'm using up my car "support" credits very fast here.
But I wanted to ask something that I not sure if a mechanic actually really knows.
And I want to dig deeper into what "could" cause it to happen again so I avoid it(if its something I'm doing wrong)
Something related to ECU's with modern cars.
Now, I do want to make it clear my car is 100% and working and all OK,
But, I wanted to know, what can make a ECU damage inside the car?
In most cases, what damages a ECU?
Slow driving?
Idling?
Leaving key in ACC position for long without starting the engine?
Stop start traffic?
High speeds?
Water/flood damage?
Or can it be something more deeper like injector faulty or something else?
I'd like to know, especially in the simpler cars, what is the usual cause of ECU failure in most basic cars?
I'll explain my situation, that happened a few months back, ECU went again, but this time I actually heard it go pop, and it happened at a parking lot at slow speeds, last time, very similar, was in traffic underneath modderfontein bridge, (didn't mention it here, as I at least knew the cause this time)
Now, like I mentioned before, car is 100% fixed and I'm driving it and all is well,
But I'm curious, what is the "root" cause? Slow traffic? Overheating alternator? Electrical short? Or is it a random thing one has no control over?
Last time it did happen, mechanic said my ECU box was very hot
And he had to replace something inside the alternator, besides the ECU and the whole shebang (again)
Was that why it happened before as well? Does the ECU box usually get hot? Could it be water damage or shorting wires inside the engine?
(Last time the mech did try pull apart my entire wiring loom to trace the problem, could he have damaged something?)
Or is it as per usual, I asking "why" too much and "over analyze" situations, and people should just put me on ignore, or I should get an infraction to shut me up once and for all....
And if it's that I ask "why" too much , as somebody once told me, you'll never know until you ask, and as I have no idea I thought I'd ask again, even if somebody Will slap me for asking again.....
