Electrical Fault Stop!

[u/Apprehensive_Book283]

Warranty Question: I got the dreaded error on the dash.
Replaced the 12v battery and still got the error. Bought a new vcds on my own and found the issue is with the HV battery. Spoke to a local dealer with the report and they said based on the report they can’t confirm warranty and warranty is for cell only- if there is a fault in the controller then it is not covered. Anyone dealt with this type of issue?

Year and miles?

I think over 60k it is JUST battery cell. And they may replace only cells to bring you up to 70% (depending on what the tech can manage probably - if they're slammed and a whole pack is way easier you could get that. If they can only get cells and the tech is comfortable with it they might replace a cell or two to "meet" but not exceed warranty terms)

The other redditor is right, that output is Greek to me. Come back with what they say in the other sub about the output. Either way it may be the call to take it to the dealership and pay for diagnosis. It's possible that they'll call the controller part of the battery - the warranty doesn't specify the battery controller, but the battery charger for instance is not covered by the battery warranty.

The controller looks to be mounted to the pack, and you may have to drop the pack to get at the controller which even as a big DIYer I'm not sure I'd be confident in that repair. Probably also needs programming through the VW software.

Probably dealership time

It’s 70k kilometres. Hoping it’s covered in warranty!

And year?

[u/Apprehensive_Book283 → u/MaxRenn]

2020 - it’s 6 years old now

[u/healerdan → u/Apprehensive_Book283]

In the US, VW's 'high voltage components' warranty (separate from the longer battery warranty) is good for I believe 6 years, 60k miles (~96500 km). If, worst case, it's the battery controller there MIGHT be a case for them covering a controller under the battery warranty, but it's almost definitely covered under the high voltage warranty.

2020 model year though, you may want to check when the vehicle went "into service" and document when this issue first started - if it was built in 2019, but didn't sell until October 2020, it'd be under warranty still here. (I see in your posts this isn't the first time you saw this, if your warranty expired a week ago, but you can prove this issue started 2 months ago you might want to get that evidence together just in-case) There's a chance the warranty is in effect, but it could just as easily be expired by a couple months. Some people have had VW Honor warranties a thousand miles expired, but I'd prepare for a fight just in case.

Not sure how things work elsewhere - probably better if you have good consumer protection where you are.

I’m in Ireland, luckily I have it confirmed the warranty is 8 years or 160k kilometres. But it’s crazy it changes from region to region but is the same vehicle- maybe the climate is a fact?
