VW Sharan Temperature Mystery: Blocked Radiator Alert

Having dealt with similar symptoms on my 2013 VW Touran diesel, I can share my experience. I have some experience working on VAG diesel engines and basic cooling system maintenance. The symptoms you describe match what I encountered. My radiator grille was partially blocked, restricting airflow to the cooling system. However, the root cause turned out to be a blown fuse controlling the engine temperature sensor circuit. The fix was straightforward, the workshop replaced the faulty fuse and performed a diagnostic scan to clear the check engine light. Total cost was 52€, including the diagnostic work. To better assist you, could you provide: Current mileage, Any recent maintenance work, Specific temperature readings you are seeing, Whether the cooling fan is running normally, Any unusual sounds from the engine bay While automotive cooling issues can be complex, starting with the basics like checking for radiator blockage and electrical components often reveals the problem. A proper diagnostic scan would confirm if its a sensor issue or an actual cooling system problem. Based on my experience, having these symptoms checked promptly helps prevent more serious engine damage. The temperature sensor circuit being compromised can mask actual cooling problems.

Last service was at 15936km and the workshop diagnosed an electrical fault with the temperature sensor circuit. The diagnostic scan showed error code P0128, pointing to the thermostat/coolant temperature below regulation. The radiator grille was indeed partially clogged with debris, restricting proper airflow to the automotive cooling system. After clearing the blockage and replacing the faulty sensor, the engine temperature returned to normal range. The cooling fan now operates correctly and the engine warms up normally. Total repair cost including parts and labor came to 285€. Worth checking as these issues can lead to car overheating if left unaddressed.

Thanks for the update on your Sharan. The P0128 code matches exactly what I experienced with my Touran. The combination of a restricted cooling grille and faulty sensor created those misleading temperature readings. The repair cost sounds reasonable given they fixed both the electrical and mechanical issues. My initial fuse replacement was just a temporary fix, I ended up having similar work done a few months later, costing around 290€. The automotive cooling system on these VAG diesels is generally reliable, but debris accumulation in the radiator grille is a common problem that often goes unnoticed until temperature-related issues appear. For anyone reading with similar symptoms: the combination of slow warm-up times and erratic temperature readings often points to both sensor and airflow restrictions. Getting both checked simultaneously saves time and prevents potential car overheating issues. Since having these repairs done, has anyone else noticed their engine temperature stays more consistent, especially during longer drives?

Thanks for the input. The car has been running perfectly for the past month since the repair. Engine cooling is now consistent and warm-up times are back to normal. The temperature gauge shows steady readings and the check engine light has stayed off. For those wondering about my specific fix: clearing the radiator blockage made a noticeable difference in airflow. The restricted airflow from the clogged cooling grille was definitely contributing to the erratic temperature behavior. One tip from my experience: regular visual checks of the radiator area can prevent similar issues. Car overheating problems often start with simple maintenance oversights. The 285€ repair cost was worth it to prevent more serious engine damage. Will definitely keep monitoring the temperature gauge more closely now. Such a relief to have proper engine cooling again, really makes a difference in how the car runs.
