Removing and installing E-box on left side of engine compartment (engine compartment E-box) — VW

🧭 Before you start

Disconnect the battery, remove the E-box cover, mark the wire assignments and open the cable guide covers. Remove the wires from the bolts, unclip the wiring, renew the multiple fuse, unscrew the central bolt and lift the box off. To remove the holder, take out the air filter housing (diesel), battery and tray, slide out both flat contact housings, undo the nuts and unclip the additional relay carrier. Refit with M5 nuts at 4 Nm, M6 nuts at 6 Nm and the central bolt at 9 Nm, then make sure the cover engages.

Fits: VW Golf Cabriolet (517, 2011–2016)

Don't miss

• Mark which wire goes on which connection point before removing anything.
• Renew the multiple fuse whenever its hexagon nuts have been loosened.
• M5 nuts (AF 8 mm) to 4 Nm, M6 nuts (AF 10 mm) to 6 Nm.
• Central bolt of the electronics box to 9 Nm.
• Check the cover has properly engaged after pushing the securing bow home.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.
