Rear Right Door Lock / Latch Mechanism

Used original-equipment Audi door locking mechanism for the RIGHT REAR door of compatible Audi A5 Sportback 8TA vehicles.

📍 WHERE DOES THIS PART FIT?

The lock mechanism is installed inside the right-hand rear passenger door, immediately behind the rear edge of the door where the latch engages with the striker on the vehicle body.

On a UK right-hand-drive vehicle this is normally described as the offside rear / driver-side rear door lock.

WHAT DOES THE DOOR LOCK CONTROL?

The latch assembly mechanically secures the rear door to the body and interfaces with the vehicle's central locking system. Depending on vehicle equipment, the assembly also provides door-lock/door-open status information used by the vehicle's convenience and security systems.

It is therefore more than a simple mechanical catch. Correct operation is important for secure door closure, central locking and correct detection of the door's status.

⚠️ COMMON SYMPTOMS OF A FAILED LOCK

These symptoms can also be caused by wiring, connectors, handles, cables, control modules or mechanical alignment. Diagnose the fault before replacing parts.

🔎 VEHICLE COMPATIBILITY

A5 Sportback engine families documented with this reference include:

1.8 TFSI • 2.0 TFSI • 2.0 TFSI quattro • 2.7 TDI • 2.0 TDI • 2.0 TDI quattro • 3.0 TDI quattro • 3.0 TFSI quattro • S5 quattro and other 8TA applications depending on specification.

❌ DO NOT ASSUME THIS FITS

This listing is specifically for a REAR RIGHT lock.

Do not order it as a replacement for a front-door lock, rear-left lock, or a physically/electrically different latch merely because the vehicle is an Audi A5.

The A5 Coupe and Cabriolet do not have the same rear passenger-door arrangement as the 5-door A5 Sportback and must not be assumed compatible from the A5 name alone.

Later-generation A5/F5 vehicles must also not be assumed compatible.

Other Audi/VAG models may share cross-referenced lock families, but THE PART PILOT will not claim those vehicles as confirmed fitment without matching the VIN / vehicle specification and exact lock configuration.

PART NUMBER INFORMATION

8K0839016C

Also formatted as 8K0 839 016 C.

Replacement catalogues also cross-reference 8K0839016F within this rear-right lock family. A cross-reference is not permission to ignore the physical/electrical specification of the original component.

WHY CHOOSE AN ORIGINAL-EQUIPMENT USED PART?

A used factory-specification component was manufactured for the vehicle platform and provides the original mounting geometry, connector arrangement and operating characteristics when the correct reference is selected.

Low-cost pattern replacements can vary in manufacturing quality, actuator performance, connector tolerances and mechanical refinement. For a component that physically secures a vehicle door, accurate fitment and reliable operation matter.

Buying a quality used component can also provide substantial savings compared with purchasing the equivalent part new — in some cases used automotive parts can cost up to 70% less than new equivalents.

🔧 FITTING GUIDE

Indicative procedure — professional installation recommended.

1. Switch off the ignition and secure the vehicle.
2. Remove the right-rear interior door trim using suitable trim tools.
3. Disconnect relevant electrical connectors.
4. Release the internal handle/lock Bowden cable as applicable.
5. Move/remove any access panel or carrier components required for access.
6. Disconnect the electrical connector from the latch.
7. Remove the latch retaining fasteners at the rear edge of the door.
8. Withdraw the existing mechanism carefully from inside the door.
9. Compare old and replacement units before installation.
10. Install the replacement mechanism and reconnect cables and wiring.
11. Test locking, unlocking, interior/exterior handles and door closure before refitting trim.
12. Refit all removed components and perform a final operational check.

Indicative labour time: approximately 0.75–1.5 hours depending on vehicle specification, technician experience and whether additional door components require removal. This is an estimate, not a manufacturer labour-time quotation.

♻️ REUSE • SAVE • SUPPORT SMALL BUSINESS

Choosing a serviceable used automotive component gives an existing part another useful life rather than automatically replacing it with a newly manufactured component. Reuse helps reduce demand for new materials and avoids serviceable automotive parts being discarded unnecessarily.

Your purchase also supports an independent UK automotive-parts business and helps us continue inspecting, identifying, storing and supplying reusable vehicle components.

🌍 ♻️ 🚗 GOOD PARTS DESERVE A SECOND JOURNEY. 🚗 ♻️ 🌍

Parts are prepared and packaged for transport with appropriate protective materials. Always inspect the parcel and component after delivery and before installation.

DO NOT ORDER FROM REGISTRATION, MODEL NAME OR YEAR ALONE.
