Localization and replacement of the external temperature sensor on the BMW Series 3 E90.

Model: BMW Serie 3 E91, E90, E92 - Years 2005-2013
Part: Checks and maintenance

In this video, we can see where the external temperature sensor of the BMW Series 3 E90 version is located and how to potentially change it: unfortunately, it's not as easy as one might think, and to reach the sensor, it is necessary to remove the front radiator and also the fan. If we look at the front grille, at the bottom, we see a small component that protrudes, but we need to remove it from the inside, and in this case, it is not possible because it is stuck, so we have to remove the entire bumper to avoid the risk of breaking it from the inside, which would force us to change the entire bumper. Therefore, something seemingly very small, like the external temperature sensor, which in most cars is located inside the exterior mirror, forces us to dismantle half the car.

How to Check the Oil Level on a Jeep Renegade?

To check the oil level on a Jeep Renegade, you need to open the bonnet to access the components inside the engine bay: on the lower left side of the engine block, you will find the dipstick for checking the level. This should be pulled out and thoroughly cleaned with a cloth: once cleaned, reinsert it back into its tube and pull it out immediately after. This way, you can check that the oil mark is between the minimum and maximum levels; finally, you can place the dipstick back in its tube.
