2005 Mercedes-Benz CL65 AMG: Double-Pane Window Glass

March 17, 2014

2005 Mercedes-Benz CL65 AMG

Our long-term 2005 Mercedes-Benz CL65 AMG's cabin is extremely quiet. Regardless of highway speed or bustling city noise, there is almost no impact on the interior. The radio can be played at a lower volume, conversations can be heard easily and commutes are less grating as a result. The double-pane glass used for the windows is partly to thank for this, but it also has an unintended consequence.

Like many other Edmunds employees, I'm used to waving my parking pass around until the gate to our garage notices it and raises the gate. Some cars (like our Tesla Model S) have windshields that block the card reader, so you have to use the side window instead. The CL65 however, doesn't let any signals in or out from the front or side windows.

As a result, I have to roll down the window on the CL65 and wave my parking pass around outside the car. The same is true with my garage door opener at home. Unless I roll down the window, the garage door stays closed. It's a bit annoying when you've just had the car washed (I've taken to just opening the door to avoid a streaky driver window), and I probably look silly flailing my arm about outside the car, but it's really a small price to pay for a very serene city commute.

  • is it the dual pane that is causing the problem or some type of heat rejecting treatment added to the glass that does it? I know some of the clear heat rejecting window films can block radio waves.

    I think zim is right, Mercedes has a different treatment on their windows and that is the cause of the signal issues. This is probably the blue tint of most Mercedes glass compared to other cars' green. Glass is technically radio transparent...

    Check the manual. In my 2003 S500, there's a "window" of opening in the front windshield for this purposes. In my car, it's the area right underneath the rearview mirror, about 5" by 5" square. The manual has a drawing of it. Give it a try.

    Warning: off-topic. Maybe this is a reflection of how far automakers have come in the last ten years, but other than a ton of features, this interior doesn't strike me as "luxurious". For a better perspective I just watched Donna's interior movie, and I was left with the impression that it's quite cheap. Do you guys feel this way when you're driving it?

    @greenpony, Car makers absolutely have come a long way in the last 10 years, but even by modern standard the W215 is a pretty darn nice place to be. The switch gear used in ALL MB's of this vintage was not great so there is definitely room for complaint t

    "The same is true with my garage door opener at home. Unless I roll down the window, the garage door stays closed." Most people would program one of the buttons on the rear view mirror to open their garage door.
