Detailed Description

The Beru ZS043 is an ignition coil designed for distributorless ignition systems where the coil mounts directly on the engine head. Its plug-top format and cylinder shape support OE-style replacement on vehicles that use this coil architecture. This part number is listed for 1995-1998 Audi A6 Quattro and 1995-1997 Audi S6 applications with OE No. 034905101. This part cross-references 034905101 and 034905105 for the same application.

Beru, backed by BorgWarner OE manufacturing expertise, develops ignition components in cooperation with vehicle and engine manufacturers and validates them through proprietary testing. The result is an aftermarket ignition coil built around OE specifications and fitment-focused replacement needs for Audi ignition service.

Common Issues This Part Can Address

• Engine misfire caused by a failing ignition coil
• Hard starting related to weak spark output
• Rough idle from inconsistent coil performance
• Loss of power under load due to ignition breakdown
• Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify the OE number and connector style before installation. This coil mounts on the engine head and uses a 2-wire, male-terminal configuration, so matching the original electrical connection is important. Inspect the spark plug condition, coil boot area, and related ignition components during replacement to help confirm the source of the fault.
