A blown fuse #14 in your Audi often points to a fault within the comfort module system, triggering the dreaded Vcds Code 01570. This guide outlines common culprits and troubleshooting steps to help you pinpoint the issue and restore functionality.
Common Causes of VCDS Code 01570
Several components connected to the comfort module can cause fuse #14 to blow, resulting in a VCDS code 01570. These often include:
Footwell Lighting
The rear footwell light, located under the driver’s seat, is a frequent offender. Wiring issues within the seat can cause a short circuit. Disconnect the two-wire black connector for the rear footwell light to see if this resolves the issue. Inspect the wiring for damage or contact with metal parts of the seat frame.
Driver’s Door Locking Motor
A malfunctioning driver’s door locking motor can also contribute to this problem. Test the locking motor to ensure proper operation. This may involve using a multimeter to check for voltage and continuity.
Window Motors
While less common, faulty window motors can overload the circuit. Manually test each window motor with a test lead to rule out any issues.
Rear Cabin Overhead Light
Problems with the rear cabin overhead light’s wiring, such as cracked solder connections, can lead to a short. Inspect the wiring and solder joints of the rear cabin overhead light for damage. Resolder any cracked connections.
Sun Visor Wiring
Wiring within the driver’s side sun visor can short circuit, especially above the headliner. Remove the sun visor screws and lower it slightly to check if the problem disappears. You may need to partially lower the headliner to inspect and reroute the wiring.
Wiring Harness Crimps
Damaged or corroded crimps in the wiring harness along the driver’s door sill or behind the central locking module can also cause shorts. Carefully examine these areas for any signs of damage or corrosion.
Conclusion
Troubleshooting VCDS code 01570 involves systematically checking the common problem areas outlined above. By isolating and addressing the faulty component, you can resolve the issue and restore your Audi’s comfort module functionality. If the problem persists after checking these areas, further diagnostics with a VCDS scan tool may be necessary to pinpoint the exact cause.
