Encountering a P068A error code in your Volkswagen can be frustrating, especially when it’s accompanied by starting problems and electrical glitches. This fault code, indicating “Power Relay De-energized Performance Too Early,” suggests an issue within your VW’s power management system. Let’s break down what this code means, what symptoms to look for, and how to potentially address it.
The P068A code essentially tells you that the power relay in your Volkswagen is shutting off sooner than expected. This relay is crucial for distributing power to various components in your car, including the engine control unit (ECU) and other vital systems. When it malfunctions, it can lead to a range of problems.
Common Symptoms Associated with P068A:
- Starting Issues: This is a frequently reported symptom. You might experience difficulty starting your VW, requiring multiple attempts. In some cases, the car may not start at all, even with a jump start. Leaving the car for a short period might sometimes improve the chances of starting, as mentioned in the original query.
- Electrical Problems: Issues with accessories like the sunroof and windows can surface. These may operate erratically or fail to function altogether.
- Battery Drain: Although not explicitly stated by the code, a faulty power relay could contribute to unusual battery drain in some scenarios.
- Low Voltage Readings: As observed in the initial problem description, voltage readings might be lower than normal, even with a new battery.
Possible Causes and Troubleshooting P068A in Your VW:
The most likely culprit behind the P068A code is indeed a failing power relay. Relays are electromechanical switches that can wear out or become faulty over time, especially in vehicles with higher mileage.
Steps to Consider:
-
Inspect and Replace the Power Relay: The first and most logical step is to locate and inspect the power relay. The part number provided in the original post,
5C0951253A, seems to be a relevant accessory power relay for Volkswagen vehicles. You can verify its compatibility with your specific VW model (like a 2014 Jetta) using online parts databases or your local VW dealership.-
Location: Relay locations can vary depending on the VW model and year. Consult your owner’s manual or a vehicle-specific repair manual for the precise location of the power relay in your car. Relays are typically found in fuse boxes, often located under the hood or inside the cabin.
-
Replacement: Replacing a relay is usually a straightforward DIY task. Once you locate the relay box and identify the correct relay (refer to diagrams in your manual), you can typically pull it out and push in the new one. Ensure the new relay is the correct type and specification.

-
Check for Wiring Issues: While less common, problems in the wiring harness related to the power relay circuit could also trigger the P068A code. Look for any signs of damaged, corroded, or loose wiring around the relay and related components.
-
Battery and Charging System: Although the user in the original post replaced the battery, it’s still worth re-checking the battery terminals for cleanliness and proper connection. Also, ensure the charging system (alternator) is functioning correctly, as indicated by the voltage reading of around 13.8V when the engine is running, which seems normal.
-
Sunroof Leak and Electrical Issues: The mention of a past sunroof leak is interesting. Water intrusion into the car’s electrical system can cause corrosion and malfunctions over time. While the leak may be resolved, residual damage could still be affecting electrical components. Thoroughly inspect wiring and connectors in areas potentially exposed to the leak.
Is Replacing the Power Relay the Solution?
For many VW owners experiencing the P068A code and related symptoms, replacing the power relay has resolved the issue. Given the relatively low cost of a relay, it’s a reasonable first step in troubleshooting.
Seeking Professional Help:
If replacing the power relay doesn’t fix the problem, or if you are uncomfortable working on your car’s electrical system, it’s always best to consult a qualified mechanic or a VW specialist. They can perform a more in-depth diagnosis to pinpoint the exact cause of the P068A code and ensure proper repairs. They can also check for any underlying issues, like parasitic battery drain or more complex electrical faults.
By systematically investigating the power relay and related systems, you can effectively address the P068A code in your VW and get back on the road with confidence.
