Guide to Cleaning Sensors

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Engine

There are certain actions you must take to clean the sensors and others you must avoid. Do not use corrosive liquids like gasoline or alcohol, do not use compressors, and do not immerse the sensors in liquids. To optimally perform this cleaning operation, it is best to work on a table or have a flat surface to work on. Use sprays typically used in electronics to clean circuits. It is advisable to perform this operation while keeping the spray nozzle at a certain distance, about 4-5 millimeters. The liquid from the spray used dries quickly.

How to Remove the Rear Bumper on the Ford Fiesta

The preliminary operation is to detach the rear wheel arch from the bumper to access the screws underneath that secure the bumper (the wheel arch detaches by extracting the two plastic screws with a lever). Now unscrew all the screws around the perimeter of the bumper (you can see them by opening the rear hatch) and now you can detach the plastic from the bodywork by gently pulling it outwards: during this operation, be careful not to break the locking pins. Once you have extracted and replaced the bumper, you can reposition it and secure it by following the same operations done previously.
