Cigarette Lighter Socket Failure – Diagnosis

• Socket not powering devices: Check fuse first (typically 15–20A in BMW fuse box). If fuse is good, measure voltage at connector Pin 1 with ignition on – should read 12V.
• Socket works intermittently: Wiggle the connector while monitoring voltage – dropout during wiggling confirms a loose or corroded terminal at the 2-828815-1/2-828816 connector.
• Fuse blows repeatedly: Inspect socket for foreign objects causing a short circuit before replacing the connector.

Frequently Asked Questions

Q: What is the difference between 2-828815-1 and 2-828816?
A: 2-828815-1 is the male plug housing (harness side); 2-828816 is the female socket housing (socket side). For cigarette lighter socket repair, you typically need the female socket (2-828816) which connects to the socket body.

Q: Can this connector be used for a 15A circuit?
A: Yes. The 2.5mm series is rated for up to 10A per pin. For a 2-pin connector with both pins carrying current (power and ground), the effective circuit capacity is 10A – sufficient for standard 12V cigarette lighter loads (phone chargers, dashcams, etc.).

Q: Is this connector compatible with non-BMW vehicles?
A: The 2-828815-1 / 2-828816 is a TE Connectivity standard part used across multiple OEMs. Cross-reference your OEM part number to confirm fitment on non-BMW applications.
