Very true.
I had a Citroen DS in not so long ago with warning lights like a Christmas tree, Stop/Start failure a LIN network fault code.
Turned out to be the alternator.
It was doing everything an alternator should do but because it couldn't be identified on the 'network', I had to replace it at enormous cost to the customer (for an alternator!) plus labour to fit.
Sorry for drifting 'off thread' but it's just ridiculous how things have become.
