13 articles on retrofits, module swaps, CCS2, and other tweaks that make a Tesla nicer to live with.
Key differences in cameras/processors/capabilities, with production dates. AP1 (09.2014+) → AP2 (10.2016+) → AP2.5 (2017) → AP3 (2019) → AP4/4.1 (2023+).
A CCS2 retrofit is the module or kit that lets a Tesla charge at CCS2 DC stations. Who needs one, whether a Tesla will fast charge without it, which module to fit on Model 3/Y (82-B, 00-B, 20-B) and on Model S/X, the official CCS upgrade, 2026 prices and common errors after installation.
The 54/75 kWh packs (pre-facelift) are generally more stable than 82 kWh, but imbalance is possible. What to look at when buying and servicing.
LG 79 kWh (EU) shows the lowest failure rate per field reports. A good balance of longevity and charge.
Early 980 rear motors had inverter failures. Symptoms and repair guidelines.
By field reports the '990' shows good reliability and longevity. The best pick for a pre-facelift.
LFP batteries (CATL/BYD) are a good choice for long-term ownership: low degradation with daily 80–100% charging and simple operation. Usually fitted to RWD.
An American modem in Belarus only picks up LTE; the European and global ones add 3G. Why you cannot load your own eSIM into a Tesla, how a physical SIM is fitted and activated, how much data it needs and what makes the connection drop for a second.
Some Model Ys with the new 4680 batteries (USA, Gigafactory Texas) have shown traits that complicate battery service and repair: the structural battery pack is harder to repair, and mass production of the 4680 is facing difficulties.
The ~100 kWh Palladium pack on Tesla Model S/X Plaid and Long Range (2021+ refresh): 7920 Panasonic 18650 cells, more reliable voltage sensing, but the floor is vulnerable to impacts and moisture.
Why HomeLink doesn't trigger modern rolling-code gates and how to fix it: external universal receiver, Wi-Fi gateways (MyQ and similar), wired control input.
As of October 2026 there is no free Premium Connectivity left: on 30.09.2026 Tesla shut down the “forever” Latvian subscription, and since early September Tesla demands a vehicle registration certificate and a driver's license every single time a car is linked to an account. The only working route is a paid subscription through a region where Tesla sells: Canada 13.99 CAD/mo, USA $9.99, Poland 35 zł, EU and Latvia €9.99. In October 2026 the chat described a working scheme for moving a car to the Polish region with genuine Belarusian documents: 5 of 5 cars passed Tesla's manual review. Payments from Belarus go through BSB cards.
How to live with a NACS connector in a Type2/CCS2 world: home AC, public stations, EU Supercharger, which adapters really help and where a retrofit is required.
