Problems with oil light, engine noise and overheating in Opel Zafira 2021 - Possible defect in engine oil temperature sensor?

Hi, I actually experienced something similar with my Opel Astra (built in 2019, diesel) and have some experience with car repairs. The problem back then was "coolant level too low". I went straight to my trusted garage and we checked everything thoroughly. They replaced the faulty coolant sensor and it cost me 52.5 euros. Now my Astra is running like a champ again. However, before I can help you more specifically, it would be good to know more about your technical specifications. For example, what about the general condition of your Zafira?

Thank you for sharing your experience with me. My Zafira already has 58049 km on the clock and the last service was recently. I actually take good care of it, so there's no obvious damage or anything. I take it for regular servicing and keep to all the maintenance schedules. So I hope it's not too complicated. Anyway, I'll take your story about the coolant sensor into consideration. Thanks again for the tip!

Hey, no problem! Glad to hear you're taking good care of your Zafira. I agree, it does sound like there is something wrong with the sensor. In my case, it was pretty easy to fix and didn't cost the earth. It's good that you're taking your car in for an inspection to be on the safe side though. I'd be delighted if you could keep us up to date and let us know how it goes. Maybe your experience will help other Zafira owners later on. Good luck and hopefully it's nothing serious!
