Battery Energizer or OEM Volkswagen

I just ordered the energizer lithium fob battery, will see if it lasts longer than the regular energizer which in my case was 3 years

I didn't get long lasting power from "any brand name". Switching to Energizer or Panasonic did much better, like 2 years.

I had U350100 as a soft fault in my Tiguan's system for a while about a year ago. I had it throw a hard fault and CEL for the same code twice. I found this to be caused by a fatiguing main battery. Not able to hold a high enough charge constantly to keep all the systems happy. I replaced and coded the replacement battery (000-915-105-CC-DSP) from VW. Made sure to change it's coding to know it was an AGM battery I installed in the Tiguan. Fault has not returned since.

Now I stick to Energizer Max batteries, they claim a 10 year shelf life, and I have some that are 5 years old that are still near 100% state of charge, with no leaks.

When you change/disconnect the battery you will have the dash light up....just drive it and they clear out once you hit ~10mph.

I had an Energizer battery last 13 years in my ranger. Problem was when it came time to change it I couldn't find them anywhere.

Bought my Energizer back in 2013, haven’t let me down once :)

I installed a new battery but now the car won't start or turn over.

Name brand but avoid ebay. I bought some energizers and panasonics from more than one (supposedly reputable) ebay seller a while back that didn't last more than a month or so.

On the other end of the spectrum, the eGolf sucks. It wasn’t good when new and I can’t imagine spending that kind of money to repair it.
