VW Fox Temperature Sensor Issues, Multiple Failures

Based on my experience with a similar issue on my 2009 VW Polo diesel, I can relate to these temperature sensor troubles. I have some experience working on VAG vehicles and recently dealt with comparable symptoms. The symptoms you describe match what I experienced, multiple temperature-related issues pointing to a sensor malfunction. In my case, the vehicle temperature gauge was showing incorrect readings, and various temperature-dependent systems were misbehaving. After taking it to my regular workshop, they diagnosed a faulty wiring connection to the temperature sensor. The repair involved sensor replacement and recalibration of the new component. Total cost was 95€, which included parts and labor. The sensor calibration process was necessary to ensure accurate readings and proper system function. After the fix, all temperature-related issues were resolved, including climate control and auxiliary heating systems. To provide more specific guidance for your case, could you share: Current mileage on your Fox, Any check engine lights or specific error codes, When these symptoms first appeared, Whether the problems are constant or intermittent, If any recent repairs were performed This information would help determine if your issue is identical to what I experienced and whether the same fix might work for you.

I had the exact same symptoms on my Fox, and replacing the outside temperature sensor fixed everything. The temperature monitoring system is working perfectly now. After the sensor replacement, all systems came back online, AC, washer nozzles, and mirror heaters. Had my last service 3 months ago at 51848km. The temperature sensor calibration was straightforward and included in the repair. Total repair cost was 85€ for parts and labor. The whole fix took under an hour. A quick scan with diagnostic tools confirmed the sensor was the root cause. After the repair, no more error codes appeared and temperature readings are now accurate.

Thanks for sharing your positive experience with the temperature sensor replacement. Its helpful to know the fix worked well on your Fox. This matches exactly what happened with my Polo, all temperature-dependent systems returned to normal operation after addressing the sensor issue. One thing worth mentioning about the outside temperature sensor repair is that proper calibration is crucial. Like you, my repair costs were reasonable at 95€, only slightly more than yours. The sensor malfunction symptoms were identical, and the fix was equally quick and effective. For others reading who might face similar issues, the key signs that point to a faulty vehicle temperature sensor are: AC system not engaging, Frozen washer nozzles despite normal temperatures, Non-functioning mirror heating, Erratic temperature gauge readings, Related error codes in system diagnostics The combined symptoms make sensor replacement a logical first step in troubleshooting. Professional diagnostic confirmation is still recommended before proceeding with repairs.

My experience with fixing the temperature sensor issue on my Fox has been completely successful. After getting it repaired 3 months ago at 51848km, every temperature-related system is working perfectly. The car temperature sensor replacement solved all the problems, AC runs great, washer nozzles spray normally, and mirror heaters function as intended. The diagnostic scan clearly showed the sensor malfunction, and replacing it was the right call. The sensor calibration process was included in the 85€ total repair cost, making it a cost-effective fix. The vehicle temperature gauge now shows accurate readings, and no error codes have appeared since. For anyone else experiencing similar symptoms, getting the temperature sensor checked is definitely worth considering. The repair process was quick and straightforward, taking less than an hour. Looking back, Im glad I addressed this issue promptly before it could cause any additional problems.
