Coil Pack Harness Connectors for EA888 Gen 3

Overview

Broken coil pack harness connector clips? Be sure to check which harness connectors you have and select 8K0 or 4D0 accordingly. Part number if on the back of the harness connector.

We recommend taking advantage and add a coil grounding kit while the harness connectors are apart.

The Volkswagen 4D0 971 994 and 8K0 971 994 is a genuine OEM 4-pin electrical connector housing used throughout a wide range of Volkswagen and Audi vehicles. Designed to OEM specifications, it provides a secure, weather-resistant connection for various engine management and electrical components, making it an ideal replacement for damaged or brittle factory connectors.

On many modern VW and Audi applications, this connector is commonly used for ignition coil connectors, although it is also found on other engine sensors and electrical components depending on the vehicle and engine configuration. Replacing a cracked or broken connector helps restore a reliable electrical connection and prevents intermittent faults caused by poor terminal contact.

Fitment

The easiest way to identify which one you need is to unplug one ignition coil connector and inspect the molded part number on the underside. The first three characters will be either 8K0 or 4D0. Vehicle model year alone is not a reliable indicator, as Volkswagen used both connectors during production depending on the harness supplier.
