What causes the Volkswagen to display abnormal oil pressure and then disappear quickly?
2 Answers
There are multiple reasons why a Volkswagen may display abnormal oil pressure and then disappear quickly: 1. The vehicle's oil filter screen is clogged. 2. The engine oil level is low. 3. Oil: The engine oil being used does not meet the required standards, or the oil has not been changed for an extended period. 4. The engine's oil pump is malfunctioning. 5. There is an oil leak in the engine. Below is relevant information: 1. Function: Engine oil serves seven major purposes in the engine: lubrication, cooling, cleaning, sealing, rust prevention, shock absorption, and wear resistance. Among these seven functions, lubrication and cleaning are the most critical. 2. Engine operation: Engine components naturally experience some wear during operation. When lubrication is insufficient, the wear becomes more severe, generating more metal debris. Oil contaminated with a large amount of metal debris will further accelerate component wear, creating a vicious cycle.
I've encountered this issue myself while driving. The oil pressure warning light on my Volkswagen dashboard flashes briefly and then disappears, which is quite annoying. The most common causes are a dirty or loose sensor. The oil pressure sensor is located near the engine, where dust accumulation can easily trigger false alarms. Another reason could be temporarily low oil pressure during cold starts, especially in winter when the oil pump hasn't fully circulated the oil before the warning appears. Don't underestimate this flashing warning. First, check the oil level using the dipstick to ensure it's in the middle range. If it's too low, there might be an oil leak or burning issue. Additionally, wiring connection problems are common—corroded or loose connectors can interrupt the signal, causing the warning to flash and disappear. My advice is to pull over immediately and recheck the situation. Avoid driving long distances with this issue. It's safer to visit a repair shop and scan for trouble codes using diagnostic tools. Regular maintenance, including oil changes, can help prevent such faults.
