BMW 4 Series

The 3 Series coupé, convertible and Gran Coupé given their own badge from 2013 — so 3 Series information applies to the powertrain in full, and what differs is the body, the wider track and the convertible's folding roof. That roof is worth naming: on the F33 it is a retractable hardtop with its own hydraulic pump, microswitches and control unit, and a roof that will not cycle is almost always a switch or a pressure fault rather than a body-module one.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
