(Old thread, I know, but thought it'd be best to keep it going rather than start anew.)

So I finally broke down and sprung for an OBDeleven - decent little device, though I wish we had more insight into the actual meaning of all the fields we're able to view.

Using all the info I'd gathered from this site, Reddit, and SpeakEV, I had finally come to the conclusion that I was below the 70% mark on battery capacity. After fully charging, I was seeing 14400 Wh in the "Energy Content of HV battery, RWB-internal deduction" field in OBDeleven. I figured this is roughly 60-64% of the nominal capacity.

At ~65000 miles, I decided to finally have the brake fluid changed, so while I was there I informed the service dept that I believed the battery capacity was low enough to make a warranty claim.

I am documenting the process more thoroughly in this thread on Reddit if you'd like to read more.

Bottom line is, although no one was able to say to me "Yes, your battery is less than 70%", the paperwork I was given when I picked the car up states that the battery is at 67% and that they are awaiting a decision from VW Regional.

Stay tuned for more!

Thanks for posting! Looking forward to hearing how VW resolves this.

Hope they let you know soon and that it is good news.

Just got a call from my case manager at VW Customer Care: The replacement (new? refurb?) battery has been ordered from Germany and could take up to 60 days to get here.

I don't have any updates on the logistics of the replacement itself, but at least I know they are going to replace the battery!

As someone considering the id4, I find it very reassuring that VW is honoring the warranty like this.

The battery pack is on a slow boat, but at least it's coming. Good news! It is a bit puzzling to me that VW does not keep any battery packs in stock in the USA, but I suppose there could be many reasons for them not doing this (shipping costs, manufacturing costs, low rate of failure?). I think you should get an answer from VW if you ask them about the status of the replacement cells, as I believe you are entitled to know if you are getting brand new cells or cells that at least exceed the 70% net capacity threshold. Also, do you know the warranty on the replacement pack?

I spoke further with the Service Rep at the dealership. Apparently they had a pack in California that sat unused for 18 months, but for some reason decided not to use it (didn't know/tell me why).

I suppose technically by the terms of the warranty they only have to give me something that's above the 70% threshold, but I personally can't imagine this isn't a new pack. Best case, it's a brand new 2017+ pack and I get the extra miles, worst case it's a remanufactured 2015 battery and I'm just barely over 70%.

I will post all the details when I find them out - mid-April-ish!

Thanks for the update. The 18 month old pack indicates to me VW is not in the habit of replacing packs (good to know). Maybe it had already lost some of its capacity due to being poorly protected from high temps in the summer, but that is, of course, only a guess. Thanks for keeping us updated. Yes, I hope you get a 2017+ pack.

About 30,500 miles on my 2015 SEL.

Still shows 109 miles on the Guess -O Meter when fully charged.

Showed 129 miles on the Guess O Meter when brand new in October, 2015.

I guess I didn't abuse it enough.

I suspect that you'll be getting a remanufactured battery from the motherland, as every time I've ever had to get something covered under warranty, from something as simple as a defective rear window on my Passat TDI, to the shifter linkage in park switch on the Touareg from the Motherland, which took 6 weeks for VW to finally ship the part and install it at the local dealership, the dealerships fight it.

The dealerships fought it, tooth and nail, despite being a brand loyal customer of VW products pretty much my whole life. I am sure it's because VW Germany pays the techs and dealerships cr*p for warranty work repairs. The dealerships profit handsomely from when the customer has to pay for the repair, instead, so there is always the incentive for the dealership to try and avoid warranty work, and to stick it to the customer.
