What are the common faults of FAW-Volkswagen?
2 Answers
Detailed introduction is as follows: 1. Engine light on, lack of power at high speed: The computer reads fault code 00665 in the engine system - boost pressure control not reaching the control limit (static). Entering engine data stream 01-08-115 to read boost measurement values shows no abnormality. In this case, focus should be on checking the vacuum control device of solenoid valve N75, as blockage in the vacuum pipeline at the low-pressure end leads to poor high-speed regulation and lack of power. 2. Air conditioning not cooling: Check shows normal refrigerant level with no system fault codes. Reading air conditioning data stream group 1 zone 1 displays code: 8, indicating ambient temperature too low. Data stream group 4 zone 2 shows 0 degrees, which sufficiently explains that the air conditioning not working is mainly caused by the system detecting ambient temperature too low (below 3 degrees). In this case, first disconnect the battery terminal for 30 seconds to reset the system. If not restored, then check the sensor and related circuits. 3. Sagitar 1.6 engine light alarm: Computer detection shows fault code 16795 - secondary air injection system not detecting correct air flow (intermittent). Checking other major data reveals no abnormalities. Conducting self-diagnosis test on the secondary air pump shows normal operation. This situation is mostly caused by blockage in the mechanical combination valve (common issue).
I've driven several FAW-Volkswagen vehicles, with common issues including minor electrical system glitches, such as sensors randomly triggering warning lights, causing the dashboard to constantly flash errors. The engine may burn oil, especially in the EA888 models, so it's essential to regularly check the oil level to avoid damage. The DSG transmission exhibits noticeable jerking in stop-and-go traffic, accompanied by rattling noises. Insufficient air conditioning cooling is also not uncommon, possibly due to refrigerant leaks or compressor failure. Suspension wear leads to loud noises over bumpy roads, making the ride uncomfortable. Ignoring these problems can lead to more severe issues. It's recommended to have a comprehensive check-up at the 4S店 annually and drive gently, avoiding sudden acceleration to minimize wear and tear.
