“Parking brake malfunction” means there’s a problem with the parking brake system in a vehicle. Consider utilizing diagnostic tools such as VCDS (VAG-COM Diagnostic System) for pinpointing parking brake issues.
Keep in mind that solutions may vary, suggesting the importance of tailored approaches based on the unique nature of each case.
Causes of Parking Brake Malfunction on Audi
I’ve organized this section into two parts: major causes and minor causes. Additionally, we’ve arranged the list based on the ease and cost of the solutions.
Causes with affordable and straightforward solutions are listed at the top, while more challenging and expensive solutions are towards the bottom.
Problem with Relay
A troublesome “Parking Brake Malfunction” due to issues with the relay. This relay, residing both in the ECU compartment and the rear right trunk area, proved to be a culprit. Specially if you have 643 relay. In solution part you will get what to do.
ABS Sensor Problem
Another potential headache could be ABS sensors, with a spotlight on the front wheel ABS sensor. If this component throws a tantrum, it can trigger a cascade of malfunctions, including the pesky parking brake error. So keep an eye on the health of these sensors.
Tyre Size Discrepancies
Surprisingly, differences in tyre sizes on an Audi can lead to a symphony of malfunctions, ranging from ABS warnings to Track Control hiccups and, you guessed it, parking brake issues. Maintaining uniform tyre sizes on your car can serve as a preventive measure against this domino effect of errors.
Fuse Problems
15A fuse emerged as a stealthy culprit behind parking brake malfunctions. When this fuse decided to call it quits, we found themselves entangled in a web of error messages. Fortunately, fixing or replacing the fuse proved to be a simple yet effective remedy, bringing back the smooth operation of the parking brake.
Driver Door Control Module Issues
Our final but the important causes of Parking Brake Malfunction is driver door control module. We saw in many cases, glitches that triggered parking brake malfunctions, often necessitating software updates or, in some cases, a replacement of the module.
Other Minor Causes
Electrical Issues
General electrical could trigger the parking brake malfunction warning.
Weather Conditions
Coincidentally we have found some cases that extreme weather conditions, such as very cold or hot weather, might have an impact on the occurrence of the malfunction.
Debris or Foreign Objects
Instances were reported where debris, like a dime lodged under the parking brake button, caused the malfunction.
Faulty Motor
A faulty motor on the left side could be a potential cause to the parking brake malfunction.
Solution to Parking Brake Malfunction Error
I followed the same order and style as mentioned in the causes section.
Relay Replacement
If you’re experiencing problems with relays, particularly the 643 relay, replacing it with the spare 645 relay located in the ECU compartment or the trunk’s rear right section could resolve the parking brake malfunction.
Sensor Replacement
When the problem is linked to ABS sensors, especially the front wheel ABS sensor, consider changing the faulty sensor.
Ensure Consistent Tyre Sizes
Make sure all your car tyres are the same size. Differences in tyre sizes, especially after recent changes, can lead to various malfunctions, including problems with the parking brake.
Fuse Inspection and Replacement
Inspect and replace any broken fuses associated with the parking brake malfunction. Notably, a 15A fuse has been identified, and if it’s damaged, it can trigger error messages.
Driver Door Control Module
We found several cases where The Driver Door Control Module is responsible for parking brake malfunctions. But the fact is, there are more than a single solutions to fix it. Here’s what you can do:
- Software Updates: The parking brake malfunctions can be resolved by updating the software on the Driver Door Control Module. In simple words, software glitches or bugs might be causing the malfunction, and an update can fix it.
- Module Replacement: In instances where a software update doesn’t suffice, users have opted for replacing the Driver Door Control Module. This means swapping out the existing module with a new or refurbished one if you are on budget. This solution is more comprehensive and is typically pursued when the issues are deemed beyond a software-related fix.
Check the Latch
When dealing with parking brake issues, check the condition of the door latch along with the driver door control module. If problems still not gone then you may need to replace the latch. Also, check the latch’s response with the software adjustments. Make sure to visually inspect the latch regularly to keep it free from debris or damage, ensuring a reliable parking brake system.
Other possible solutions
- Soft Reset: Perform a soft reset by turning off the vehicle completely and then restarting it. This action was mentioned to clear the error in some instances.
- Checking for Glitches: There could be error messages as glitches in the system. If the error clears upon restarting and does not persist, it might be treated as a temporary glitch.
- Software Updates: We have seen a lot of success about parking brake malfunction on Audi with software updates. If any update available, consider updating the vehicle’s software to the latest version.
- Thorough Diagnostic Scans: This one should be on top. Conduct thorough diagnostic scans to identify specific faults or errors in the system.

Can I drive with parking brake malfunction?
The ability to drive with a parking brake malfunction can indeed vary, leading to different scenarios for drivers. It’s crucial to understand the potential situations you might encounter:
- Continued Driving with the Warning: In some cases, drivers have reported being able to continue driving despite the parking brake malfunction warning. However, it’s essential to proceed with caution.
- Engine Not Starting: On the flip side, there have been instances where the engine did not start when the parking brake malfunction occurred. This adds a layer of complexity and emphasizes the need for immediate attention to the issue.
- Gears Not Responding: Another scenario involves challenges with the gears, where they may not respond as expected. This situation can significantly impact the drivability of the vehicle.
