I can confirm rangers are able to perform the update, but it is better to have a stable strong internet connection.Recap of what we (mostly) know so far:
- All ranges of VINs from the earliest 75D builds (May 2016 to June 2017) are eligible for uncorking (though not all cars are eligible)
- A small number of cars (VIN range unclear) are ineligible for uncorking due to a missing high voltage fuse in the battery pack (early data shows this may be a small amount of factory delivered 60D's)
- Some cars that have been upgraded from 60D -> 75D have been successfully uncorked
- As of now 60Ds show up in the WARP database as ineligible, it is currently unclear if upgrading to 75D will unlock eligibility
- Some SC are still unaware of the service bulletin that came out last Thursday, however during service the bulletin is listed with your service ticket if your VIN is eligible
- Some SCs will let you come in just for uncorking, some will require you to make a legitimate appointment for something else before performing the upgrade
- Uncorking delivers the same (or slightly better) performance as new 75D's rolling off the line currently per Krash's data
- 60/75s that were built before 6/19 are not eligible for uncorking at this time
Rumors
- Unverified: An OTA update is coming to uncork cars without needing to come into a SC
- Unverified: Ranger service can perform the uncork process
- Unverified: The upgrade will eventually be a paid upgrade
(That's straight from the regional service manager for the bay area)
