Review on ๐Ÿ”ง URO Parts A/C Temperature Switch 4A0820539 by Zack Frazier

Revainrating 5 out of 5

Works perfectly on my Audi.

Not much to say about that. It fits and works. I installed it a few weeks ago after running an HVAC code scan and getting a G89 sensor error code. I've cleared the error and rescanned several times and it's been very consistent. After I installed these, the code no longer appeared and the dashboard display showed the correct temperature without hesitation, as it had for the past few months. Time will tell about durability, but so far I'm happy. .Update: It's been 9 months and it's still working as it should. By the way, when installing it, I used the simplest method I could think of. Since it's under the cabin air filter and no one will see it, I took a knife and cut a slit in the plastic above it. Then I broke the old one in half for easier removal. Then I just connected the wiring harness to the new one and plugged it into the bracket. I taped the plastic back with tape to make it look neat again. Basically, if you put the filter back in place, you can't tell what I did. Total installation time was about 5 minutes.

Pros
  • High marks for support and durability from testers
Cons
  • There are flaws
