Don't think it's genuine. Got it from ebay £30

Updateon m situation. I've change D the thermostat. When I start te car And let it run without driving and heating off, temperature goes to 90 and doesn't move. When I start driving heating off, temperature goes down to 70 and stays there. If I turn te heating on at max, temperature goes down nearly to the bottom 50, 55. Heating at mac is still blowing OK, but not to the max. What are the chances te new thermostat is faulty?!?! Can te waterpump break down in under 20k miles? If its a temperature sensor, will it show on diagnostic?

Hi, thanks for your input. I've seen the video and its a big helper. I have a £30 quote labour only so near your price with the thermostat itself. Will e doing it tommorow by myself. Fingers crossed it all goes ok

Happy that you fix your problem. Was it showing any faults on the computer or check light going on because of the faulty sensor?

Manual transmission

No issues wit te heating whatsoever. Altho with heating turned off, temperature goes to 90 89/90abd stays there. The moment I turn the heating on, temperature falls below 85, near 80. When I think about it, it does take a bit longer to warm up.

Water pump was changed about 16k miles ago with cambelt and all other stuff

Hello all. Lately I've notice that te temperature of my Octavia is wondering between the 80 and 90 degree mark. On top of my head Is a thermostat replacement, but will be happy to hear others opinions. Car is driven every morning and evening 30mile motorway drive. I la's thinking it might be from te low outside temperature, but it was almost 10 degrees today. I will be thankful if anyone can share a video guide of thermostat change. Car is MK4,. 2.0 tdi, manual Thanknyou all and stay safe.
