01367 on Audi by model: symptoms, diagnosis and fix
The B5 A4 locks its doors, trunk and fuel door with air pressure and vacuum. Both come from one central locking pump and control module behind the trim in the right-rear corner of the trunk. Inside the module, an electric motor drives a small rotary-vane pump with graphite (carbon) vanes. The pump runs until the system reaches pressure or vacuum, or until a timer cuts it off. Owners report three main ways the system fails. 1. Worn pump. The graphite impeller wears with age and eventually breaks apart. Many owners notice the locks getting slower over weeks or months before they stop working. Owners who open a failed unit often find the impeller in pieces or gone completely, with carbon dust inside. One owner first thought the circuit board was burnt, then found it was only carbon dust. 2. Water damage. Water gets into the trunk, usually past a worn trunk seal or the right tail-light seal, and wets the module. The damaged electronics can stop working. In extreme cases they can keep the pump running until it overheats and melts. 3. Leaks and over-running. A leak in the plastic air lines makes the pump run longer on every lock cycle. Common spots are the tubing at the driver's-door hinge and the small O-rings where the lines push onto their fittings. Owners warn that long over-run can eventually break the graphite impeller. A failed pressure sensor contact on the module can cause the same over-run even when the lines are tight. A scan tool may show fault 01367, "central locking pump run time exceeded."
Common Symptoms
- doors fail to lock/unlock from key or remote
- pump runs continuously until timeout
- rattling sound from trunk (shattered graphite)
- only driver's door locks/unlocks
- burning smell from rear of trunk
- interior lights / alarm misbehaving
- locks taking progressively longer to actuate over weeks/months
How to Fix
1. Check for water first. Pull back the right-side trunk liner. If the pump area or its foam surround is wet, reseal the right tail light and the trunk seal before fitting another pump, or the new one may fail the same way. 2. Time the pump. Owners with leaks report the pump running on for 8-15 seconds after locking, or until it times out. Listen for a faint hiss at each door, the trunk and the fuel door while it runs, and check the line connectors and their O-rings. A small split in a tube over a fitting can be cut off and joined with a short piece of rubber tubing. If you find no leak and the pump still over-runs, check the pins on the pressure sensor at the module's air outlet for corrosion or bending. One owner fixed his over-run by cleaning that pin and bending it straight. 3. If the motor runs but makes no pressure or vacuum, or you hear loose bits rattling inside, the graphite impeller has broken. You can replace the whole module or move the pump internals from a good donor unit into your module. 4. Replacement. Read the full part number on your module (for example 8D0862257 plus a suffix letter). Owners advise matching the suffix letter. Used units are cheap. One owner fixed his for under £5 by fitting the internals from a donor pump, and another owner says replacement pumps sell for about £30 on eBay. Owners report that the pump from older Audis (80/100, early A4) swaps in and is more robust. Newer Passat modules will not work because those cars no longer use vacuum locking. No recall or warranty extension is cited for this pump. Used modules typically cost $50-150, new ones about $300-500, and a dealer repair $500-700.

Frequently asked questions
What does 01367 mean on a Audi?
01367 stands for "Central Locking Pump Run Time Exceeded (Likely Leak)." This is a VAG (VW/Audi/Seat/Skoda) fault code indicating the central locking vacuum pump ran longer than its allowed time limit without reaching target pressure, which the system interprets as a likely leak in the vacuum-operated locking system. It typically means the doors/trunk may fail to lock or unlock properly because the pump cannot build or hold vacuum. On Audi it is documented across 1 model: A4.
What are the most common causes of 01367?
The most common causes of 01367 are: Leak in the central locking vacuum lines or hoses (cracked, disconnected, or aged tubing), Faulty or worn central locking vacuum pump (commonly located in the trunk/luggage area), Leaking door, trunk, or fuel-flap lock actuator element allowing vacuum to bleed off, Disconnected or pulled-off vacuum line at a lock actuator, Failed seals or check valve within the pump assembly. The specific cause varies by vehicle.
How much does it cost to fix 01367 on a Audi?
Published repair estimates on Audi range from $15 to $700 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
