Where this part fits on the vehicle
Primary confirmed catalogue fitment
The table below is based on the exact visible number 8K0839015C. Vehicle equipment codes can still change the required latch, so the old part number and connector must match or fitment must be confirmed by VIN and PR codes.

|---|---|---|---|---|
| Audi A4 / S4 | B8 / 8K | 2008-2015 | Saloon or Avant, rear left only | Match 8K0 839 015 C, connector, cable layout and PR equipment |
| Audi A4 allroad quattro | B8 / 8K | 2010-2016 | 5-door estate, rear left only | Exact number and VIN/PR-code check required |

This part will not fit
Not for front doors and not for the rear-right/offside door.
Not automatically suitable for A4 B7/8E or A4 B9/8W.
Do not use for a 2-door A5/S5 Coupe or Cabriolet merely because a general catalogue page mentions A5.
Do not assume 8K0839015D, 8K0839015F, 8K0839015G or another suffix is interchangeable without VIN/PR-code confirmation.
- Will not fit if your old unit has a different electrical plug, pin arrangement, cable layout or mounting body.
- May not fit vehicles with different child-safety-lock, keyless-entry, soft-close/power-latching or door-control equipment.
- Model year, registration number or eBay compatibility alone is not enough for a definitive match.
Five-point buyer fitment check
- Confirm the failed lock is in the rear-left door.
- Read the full number from your old latch and match 8K0 839 015 C.
- Compare the electrical plug shape, keying and pin layout with the actual listing photos.
- Compare every cable, lever, bracket and mounting point - not only the plastic housing colour.
- If any detail differs, send the VIN and clear photos of both sides of the old part through eBay Messages before ordering.
What this component controls
The latch grips the body striker and keeps the rear-left door securely closed.
The integrated actuator changes between locked and unlocked states when commanded by the vehicle.
Bowden cables and levers transfer movement from the interior and exterior door handles.
Depending on vehicle specification, internal switches can inform the car whether the door is open, closed, locked or safe-locked.
Common symptoms of a failing rear door lock
- Rear-left door will not lock or unlock from the remote, keyless system or central-locking switch.
- Intermittent operation, repeated clicking or a lock that works only after several attempts.
- Door remains shown as open when fully shut, causing a warning, interior light or alarm issue on applicable vehicles.
- Inside or outside handle releases inconsistently even though the cable is correctly attached.
- Latch sticks, will not release, will not hold the striker or feels mechanically rough.
- Child-safety or safe-lock behaviour does not operate as expected, depending on equipment.
Construction and part details
The moulded housing carries visible engineering-material markings including PBT-GF30+ASA, with metal latch parts and cable/lever components. The robust factory-fit design is shaped for the vehicle's original door carrier, striker geometry, connector and control system.
Why choose a used original-fit unit instead of a low-cost pattern copy?
- Correct factory mounting geometry, cable positions and connector design when the full number matches.
- Original striker engagement and door-handle travel characteristics.
- A used part can deliver substantial savings compared with dealer-new pricing; savings vary by part and can sometimes reach around 70%.
- Reusing an existing serviceable component reduces the demand for new material and manufacturing.
Fitting guide
- Park safely, raise the window, switch off the ignition and remove the key. Follow vehicle procedures before disconnecting the battery negative terminal where required.
- Protect the painted door edge. Remove the rear door-card screws and release the trim clips with plastic tools.
- Lift away the door card and disconnect switches, lighting plugs and the interior-handle cable.
- Carefully peel back the moisture barrier or remove the inner carrier/access panel as required. Avoid tearing the seal.
- Photograph the original cable routing. Disconnect the electrical plug and release the Bowden cables and clips from the latch.
- Remove the latch fasteners at the trailing edge of the door using the correct Torx or XZN/triple-square bit.
- Withdraw the old latch. Compare part number, connector, levers, cables and mounting points side by side before installing the replacement.
- Install the replacement, route cables without kinks and tighten fasteners to the manufacturer's specified torque.
- Before refitting the trim, test central locking, interior and exterior handles, child safety lock, door-open indication and alarm behaviour.
- Re-seal the moisture barrier completely, refit the door card and clear/check diagnostic fault codes if necessary.
