IFixit: PS5 optical drive cannot simply be replaced by user – Gaming – News

Your example is not immediately correct, as you indicate yourself, you have replaced the dynamo with a different type of dynamo. I once accidentally had something similar, the replacement alternator turned out to have a freewheel clutch that was used just 1 year later, which should ensure that the alternator does not rotate when the engine is running below 800 rpm (and therefore if you are starting), but every now and then you start and the clutch just does not engage. If the control is not equipped for this, it makes his ears because the engine is running but the dynamo is not, if it is equipped with it, it automatically increases the speed so that the clutch still engages, only if the dynamo still does nothing. that make his ears.

These controls are becoming more and more complex with more and more measurements. In the field of batteries, things are also becoming more complex, start-stop systems, more and more fine electronics that need more stable voltage, more and more electrical consumption, always online, keep going and then you have not arrived at the hybrid story. The time of a simple lead battery with a simple dynamo where the interior lighting burns a bit harder with the engine on instead of the engine off, that time is over.
Then you come to solutions where you have to compensate that the battery wears out, something that happens slowly, but if a new battery is suddenly inserted, then suddenly that compensation is no longer correct so then you have to tell you, hey, I just inserted a new battery, please re-learn.

Where the big problem lies is not that the steering and the car are becoming more complex underlying, or that you have to tell the steering that you have inserted a new battery, that is not your problem.

The problem is that the manufacturer is doing everything it can so that no one outside of itself can communicate with those systems. And you are lucky that there is such a thing as the EU where the EU is the only one that requires that non-branded garages, like the dealer, must be able to communicate at this level at “acceptable prices”. However, if you do it yourself you do not fall under that scheme, so BMW you can say flat, plan with it if you want to do it yourself unless you start a garage on EU territory.
In addition, the EU is the only one that requires you to be able to do basic diagnosis via OBD. Only the US also requires OBD but only to read the status of emission control, not diagnosis.

However, those systems were very simple in the past and hardly or not at all secured (see also the massive “chip tuning” in which other parameters are written to the control unit of the motor), so that it was often very easy to bypass, so that nobody really weighed it down. fell. But that is changing more & more, people are calling on Tesla because they are reverting OTA adjustments in the steering, BMW or any other want this too, they are just not technically able to do this.

Incidentally, those EU regulations are all well and good on paper, there is no control over them, someone must first start a lawsuit before looking at them. OBD at Daimler mainly complies with the US OBD scheme (they actively check, which is why they also found out about the cheating software) but EU OBD? I saw more via OBD on my 1998 year car than now in 2019 year.
