ALLDATA Repair: Inside Intelligence

• A potentially tricky job on 2001 BMW E46 emphasised the value of repair instructions direct from the vehicle manufacturer (VM) – with safety and accuracy the priorities. 

Replacing a broken window on a 2001 BMW E46 requires careful preparation and a solid understanding of the vehicle’s specifications. Frameless windows, in particular, can be challenging; without accurate data and step-by-step instructions, the process becomes time-consuming and error prone. Having the correct procedure, therefore, is essential for a safe, efficient and precise repair.

Solution

First, the groundwork needs to be done in accordance with the OE standard – to correctly remove and replace the windowpane. This is done by removing the sound insulation of the front door, which is done to gain access to the relevant components.

Next, for vehicles with side airbags, it is essential to adhere to the safety precautions to protect the system. Furthermore, particular care must be taken when removing the window glass; a left-handed screw must be loosened clockwise – the opposite way to a standard thread. Additionally, when removing the glass, be wary of damaging the rubber ring.

For convertible models, the door window glass may have an Aquapel coating, which is indicated by a white dot on the glass. This coating needs to be protected during installation.

This is a detailed and patient process, one that should only be carried out cautiously and with original data and instructions by the technician’s side.
