I have ongoing charging issue in company's garage. There's around 20 charging spots (5-7kw), and when there's lots of other cars charding, only Cupra doesn't want to charge! Happens to Cupra only, all other EVs are fine.
Now met another coworker, has some problem with hers Born!
Same problem at my wifes company, they have around 5-10 ev places, only our Born refuses to charge in like 9 out of 10 attempts (days).

At home charging works fine. Tried public charger once, worked fine (never using public chargers, but now very afraid to go on a trip if this happens somewhere in the middle on nowhere). So its something with "busy"chargers where bunch of other cars can cause some issues with the power/current.

Visited local service, they just said it works fine on their charger. No problems found.
They say its a charger problem, even tho it works for all other EVs (including VW IDs), just don't want to admit or try anything. Visited service twice.

Any advice what to do here?
Wrote an email to official Cupra contact, they just forwarded me to the local service which is useless.

Also, if you're buying Cupra, be sure to check this before!

I'll definitelly make a website and put few put few € on google ads so everyone who googles "cupra born" will see this ongoing problem, maybe that will get some attention from Cupra people.

I'm playing with room correction and FIR settings, but its really confusing what all those settings mean!

Using Umik 1 mic, a6 master edition, external Dac.

What those HM1, HM2, BK, TL target curves mean? Smoothing, is it just something visual or changes the correction as well? And what gain setting should i choose?

Some target curves sounds much worse than no DSP, like Flat target. Other sound very different from each other. With default +5db mac gain, correction helps a bit in some part of the spectrum, fixes some room modes in bass but also makes too much upper bass (hm 1 and 2).

Can't find manuals from Eversolo, only instructions it offers is how to do Fir in REW and export to Eversolo.
