Its all one unit. Take it to a tire shop and have them fix it. You can buy a new sensor for $45 ish.
We have a 2007 Passat. The tire pressure sensor broke off at the valve stem. In checking with the dealer, I was told the tire pressure sensor and valve stem are all one unit. My question is if you can use a regular valve stem and attach the sensor to it, or do you have to get the entire unit with the valve stem and sensor together.
The dealer is mucho expensive for this part and I am hoping to save some money by using a regular valve stem and existing sensor Thanks.
