Audi A4 B8 2008-2015 OSR Rear Right Door Check Strap Stopper 8K0839249C
Audi A4 B8 OSR Rear Right Door Check Strap & Stopper
Part number 8K0 839 249 C • OSR rear right / UK driver side • Used original-manufacturer component
Correct OSR fitment identification
The original title contained a number with the front-door prefix. The photographed component is marked OSR, its cover is moulded OBEN RECHTS (top right), and the rear-door references are 8K0 839 249 C for the check strap and 8K0 839 267 B for the protective cover. Do not order this item for a front door or the nearside rear door without matching every number and the photographed orientation.
The rear door check strap sits between the OSR rear door shell and the B-pillar / rear door aperture. It limits the opening angle, creates holding positions and helps stop the rear door from swinging freely into nearby vehicles, walls or passengers.

Where the part is fitted and what it controls
The check strap is a mechanical restraint. It controls the door's opening arc and detent positions. It does not operate the central locking, window motor, speaker, mirror or latch release.
Common symptoms of a worn or failed door check strap
The door rolls back or closes on an incline because the holding detents are worn.
Noise from the hinge area while opening or closing may indicate play or internal wear.
A damaged limiter can allow excessive travel and risk contact with the wing, wall or another vehicle.
Binding, corrosion or damaged rollers can make the door unusually difficult to move.
Why choose an original Audi-manufactured used component?
An original manufacturer component is made to the door's intended mounting geometry, travel length and detent positions. This helps preserve proper clearances and the expected opening feel. Low-cost copies can vary in bracket alignment, roller resistance, protective coating and service life.
Buying a serviceable used original-manufacturer component can also reduce waste and may save up to 70% compared with a new replacement, depending on current dealer pricing and availability. Savings are not guaranteed, so compare current prices before purchase.
Fitting guide
- Prepare the vehicle. Park securely, switch off the ignition, remove the key and protect the painted door edge and sill. Support the door so it cannot swing unexpectedly.
- Remove the interior door trim. Carefully release the decorative trim, remove the correct Torx fasteners and unclip the door card using non-marking tools.
- Disconnect only what is necessary. Release electrical connectors and the interior-handle cable carefully. Follow manufacturer precautions if any airbag-related connection is disturbed.
- Access the check strap. Carefully open the moisture barrier or access panel without tearing it. Preserve the seal so water cannot enter the cabin after refitting.
- Remove the old unit. Photograph its OSR orientation, then remove the B-pillar/body-side fastener and the rear-door-side fasteners. Withdraw the strap through the access opening.
- Compare before installation. Confirm the part number, bracket position, housing shape, overall length and fixing pattern match the removed component.
- Install and tighten correctly. Fit in the same orientation and tighten using the Audi specification for the exact vehicle. Do not guess torque values.
- Reassemble and test. Reseal the moisture barrier, reconnect wiring and refit the door card. Open and close the door slowly, checking detents, clearances, noise and full travel.
Suggested tools
Non-marking trim tools, Torx bit set, suitable socket and/or XZN bit matched to the vehicle, ratchet and extension, torque wrench, pick, masking tape, protective gloves and replacement door-card clips if required.
