Vehicle
BMW Z4
The two-seat roadster, and the current G29 is the interesting case: it is the same car as the Toyota GR Supra, developed jointly and built alongside it in Austria, with BMW engines and BMW engine management under both badges. So Supra information applies to the Z4 and vice versa. The E89 before it used a retractable hardtop whose hydraulic pump and microswitches are the usual source of a roof that will not cycle, exactly as on the 4 Series convertible.

Service information
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.

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.
