I thought it might be useful to have a single place where everyone who can identify a particular campaign with title and number add it here.

Thanks to all

[ WLE3 ] Replacing Vehicle (12v) Electrical System Battery

Date: 2020-07-29

Labor Time Units: 163

Information:
Due to a manufacturing error [in part 9J1-915-105-EY], there is a possibility that the internal current sensor for the 12-volt vehicle electrical system battery does not meet the required specifications on the affected vehicles.
As a result, the charge state will be calculated incorrectly and the 12-volt vehicle electrical system battery will then be totally discharged when the vehicle is parked for extended periods without an external power supply.

Part Number:
V04015001BA. 12-volt vehicle electrical system battery. qty: 1
PAF106826. Cheese head bolt, M8 x 50. qty:4

Vehicles affected: 578 in North America

[ WLD0 ] Replacing the High Voltage line between the HV distributor and the E-box

Date: 2020-07-29

Workshop Time Units: 957

Information:
It is possible that the Single Wire seal in the connector housing of the high voltage line between the high-voltage distributor and the e-box was installed incorrectly on the affected vehicles. This can result in a conductive medium entering the connector housing in some cases.
Vehicles affected: 591

Note: Many of the newer cars will already have these Campaigns done to them, either at the factory, at Port, or at the dealership before delivery. Those of us with very early cars will have the "most fun" and spend the most time with out cars in the shop.

Prior to picking up my 4S today I verified that all the latest WLG2 software updates had been completed. They also said that it had an updated 12V battery. Hope that’s true!

Is this list up to date? In particular, is the old WLG2 software campaign the latest software update for MY20?

@louv predicted something was supposed to happen last month - https://www.taycanforum.com/forum/t...date-for-taycan-week-of-november-9-2020.2183/

@awharton had confirmation that MY20 is to be upgraded to MY21 - https://www.taycanforum.com/forum/threads/do-you-have-all-the-buttons-on-the-app.2852/post-39235

@Arno mentioned spring 2021 for a software update - https://www.taycanforum.com/forum/t...uld-i-be-about-this-12v-issue.3197/post-44057

If anyone has any further campaigns that have been rolled out, please share!

My car was at the dealership recently. The service advisor confirmed that no additional software updates for my MY20 beyond WLG2. My Taycan did not require a new 12v battery, and I have not had any issues with the battery. While at the dealer, they did check for the drainage issue.

If it's any help, I had my car at the dealer at the end of November, and armed with the helpful information from this site, I asked them to check for any campaigns due on my car. This is a Taycan 4S built in March 2020 and delivered to the UK.

WLE3 relating to the 12v battery. They said this wasn't relevant.

WLD0 relating to the high voltage cable. They said a campaign WLB0 had been completed on the car in June 2020 so that looks to have been a typo on my part.

WLF2 relating to seat belt receivers. They said this wasn't relevant.

WLH5 relating to a drain plug adjustment. They said this was relevant and carried out the work.

WLG6 relating to improvements for home charging. They said this was relevant and carried out the work. They noted that various control unit software updates were also carried out.

They said replacement of the 12v battery 9J1 915 105 EY with V04 015 001 BA wasn't relevant.

There is a section at the rear of the maintenance book for recalls/campaigns, and they stamped the booked showing these two campaigns had been completed.
