I've heard two different stories about Macan - from two different German Porsche engineers
1. Macan was originally supposed to be "fewer ECU's" but they abandoned that in various corp. committees - and while it has fewer ECU's than most German car's it's no where near "one ECU"
2. Macan is very traditional and has almost an equal number of ECU's as the gas Macan
what I do know is the ECU software is not Porsche's proudest accomplishment - they were chasing bugs right up to the release in October. of 2024 even with a 1 or 2 year delay…and they are still chasing bugs…
the car's software is fragile and lacks resilience - mine is pretty good - no worse than my other Porsche's (so far) but I know for fact other Macan's have many many software faults, that are normally fixed by replacing some "hardware unit" - but never the unit "directly" responsible for the fault - apparently the interaction model is very very complex to diagnose and faults in "module a" can cause false "faults" associated with modules "b-z"....
it all works if everything is perfect, but apparently it doesn't take much to throw it out of kilter…
I know of one Macan in Porsche service for 6-8 weeks - many many driving assistant faults - continuous - reproducible and ultimately made the car un-drivable - in for service - they replaced many many ECU's - still had the faults - ultimately as a "Hail Mary" they replaced both of the rear tail lights - problems have not since happened again…go figure -car is now pretty solid and has the normal level of few if any software faults, but sometimes.
as I said mine has actually been pretty good so far…
