A Genuinely Surprising, Real Root Cause Worth Knowing About — Renault Twingo Battery
If you've had two dealers and an auto-electrician all fail to find a persistent battery drain, this is genuinely worth knowing: one documented case, after three weeks of unsuccessful diagnosis, was eventually traced to a faulty immobiliser control unit itself — replacing it resolved the drain completely, with no reoccurrence six months later. This is a genuinely surprising root cause, and it's worth mentioning specifically as a possibility if you've already exhausted the usual suspects (interior lights, glovebox, boot light) without success.
It's also worth checking the glovebox door itself, not just the bulb: the plastic door can genuinely warp slightly over time, meaning the side that operates the internal switch retreats away from the switch plunger, leaving the light triggered even when the glovebox looks closed. If you've already removed the bulb and the drain persists, checking the door's fit and alignment against the switch is worth doing.
Renault Twingo Battery: The Part Everyone Blames First, Not Always Correctly
On the Renault Twingo, more non-starts get pinned on the battery than on any other single component, and that assumption is correct often enough to justify checking it first. It's not always the real cause, though, so it's worth confirming before spending money on a replacement that doesn't fix the problem.

Renault Twingo Battery: What It Does
On the Renault Twingo, every engine start and every moment the electrical systems run without the engine turning draws on the 12V battery. Stop-start puts far more demand on that battery than older designs, given how often the engine cycles off and on — hence the need for an AGM or EFB battery instead of a standard type.
