Detail the interior

The under dash panels on the W123 do a nice job of cleaning up the interior of the vehicle but you will need to remove these panels if you plan on doing just about any job involving the dash. The panels are actually made up of two pieces that are joined at the factory and each side (driver and passenger) are removed as a single piece.

This is one of those spots where over the years your car may have been serviced by multiple people including previous owners and this can lead to parts replaced with different size fasteners and hardware. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches. If something is different on your vehicle please let us know and share your info to help other users. If you have any questions or comments or even a different procedure you would like to share please leave it below and please leave your vehicle information.

There are two under dash panels one for the driver side (red arrow) and one for the passenger (yellow).
