Tesla Model 3/Y rear OBD cover upgrade
Make the hidden OBD area close cleanly again.
Adding an OBD module, diagnostic device, wiring accessory, or power cable can make the original rear cover hard to reset. This upgraded enlarged rear OBD cover gives that area more room, helps hide exposed wiring, and keeps the rear seat space looking finished instead of improvised.
More room behind the cover
Designed to help fit added OBD modules, wiring, and small connected accessories.
Cleaner rear-seat look
Helps hide cable clutter so passengers do not see a messy accessory install.
Single live option
One current purchasable setup, so shoppers do not need to compare variants.
What this solves
For the small install problem that keeps looking unfinished.
Without it: the cover may not sit right
After adding rear OBD accessories, the original cover can feel too tight or awkward to close neatly.
Why buy it: room for real accessories
The enlarged design gives the rear OBD area more internal space for modules, cables, and diagnostic add-ons.
After install: cleaner and calmer
The rear seat area looks more intentional, with fewer exposed cables and less visual clutter.
Trust before you install
Built for a clean rear-seat finish, not just extra space.
This is a detail part, but it solves a real frustration for owners who add accessories near the rear OBD area. The page lists durable ABS plastic, an enlarged extension design, cable-hiding utility, and a fit that keeps the rear passenger area comfortable without taking up additional space.
ABS material
Current page highlights durable ABS plastic with impact resistance for everyday cabin use.
OEM-style cabin intent
Designed to blend into the rear-seat area instead of drawing attention to the wiring behind it.
