What is the reason for the flashing snowflake and S on the Citroen transmission fault?
3 Answers
Citroen dashboard flashing S and snowflake reasons are as follows: 1. Temperature: Outdoor temperature is too low. 2. Damage: Outdoor temperature sensor is damaged. 3. Signal: Signal transmission error. Relevant information is as follows: 1. Tires: The entire body unreservedly showcases performance and sportiness. Front tire specifications are 245/35R21, rear tire specifications are 295/35R21, with a tire speed rating of V, capable of reaching 300 kilometers per hour. 2. Dimensions: The Citroen GT also expresses power and strength through its massive body size, measuring 4960 mm in length, 2080 mm in width, and 1090 mm in height.
I've driven a Citroën for several years and found that the most common issue with the flashing snowflake S light on the transmission is either oil overheating or sensor failure. Aggressive acceleration in traffic jams or driving uphill and off-road can easily cause the transmission oil to heat up too quickly, triggering the warning light to flash. Additionally, low oil levels or degraded oil quality can also cause this problem, like my neighbor's car, which frequently flashed the snowflake icon due to an oil leak that wasn't repaired in time. Mechanical issues such as clutch slippage or gear wear should not be overlooked, especially in older models. Faults in the electronic control unit (ECU) are also a potential factor—sometimes restarting the vehicle can temporarily resolve it, but it's crucial to get it checked at a professional shop promptly to avoid bigger problems.
Last time, my Citroën's transmission had the snowflake S flashing, which really scared me. It turned out that the transmission oil was dirty and needed to be changed. I had delayed the maintenance until 80,000 kilometers, which caused the problem. When driving, long-term aggressive acceleration or frequent stop-and-go in traffic can cause the oil temperature to soar, triggering the warning light. It's recommended not to slack on regular maintenance—change the oil every 40,000 kilometers or two years, and avoid overloading the car, such as climbing hills with a full load of luggage. Checking the dipstick is simple and practical; first, check the oil level yourself to see if it's normal before deciding on the next step.
