Antenna problem. Need windscreen replaced???
So I got my car back from Service today. I asked Mercedes Benz about my antenna problem. Its a minor issue. When the rear-window-de-mister is on, the FM stereo crackles.
The repair according to Mercedes.... replace the windscreen with the antenna. Sounds a bit overboard to me. An it only happens on FM band. No window tint on my car by-the-way.
The report says; 'Have carried out a burn in test to see if fault clears and hasn't. Needs a new windscreen as the antenna is the rear window is defective. $2200 fitted'. I also paid $76 for that test.

Long before replacing the rear screen.
There is a sticky connector pad at the top dead center of the screen under the roof lining. Give it a good shove to make sure it is making proper connection. Comes loose in the sun. Also check the antenna amplifier connections & earth under the LHS rear C pillar cover.

Why doesnt Mercedes do this? They charged me over $75 just to tell me the window needs replacing.

That's a good question that I can't answer. The trouble with many dealers is that they are just parts replacers. That can't diagnose Diddely Squat!

Exactly. They only go by the computer. Hence a few forum members including me got told the fish story that the AUX cable isn't compatible when the cars built with the adaptor plug.

Also not all dealers are going to do anything but replace parts, if the pads connected to the windscreen are bad, then It makes sense to me that a new wind screen with pad is needed, since it comes as one unit and not 2 single parts then I can see why they want to replace it.
Dealers aren't the place to go for cheap fixes, nor have I seen one, do a :cheap fix: re mounting or glueing the pad may not be a permanent fix either, if thats even whats wrong. Just saying

Nick, our resident dealership apologist: $75 is a stupid figure for "replace windshield". The chances that they even LOOKED at the car? Slim. The techs at my last dealership appt put my car down as being a white 2007 C230.. but told me they inspected it.. Not sure how they missed the big details like the silver paint and four-cylinder engine.
As Glyn said, dealerships don't know how to diagnose or "fix" anything. They replace repairable parts at HUGE expense which is why they should be avoided like the plague.

What kind of adhesive?
My antenna (plastic piece)on the driver side above the headliner is not attached very well to the glass. If I press it onto the glass my keyless works. What kind of adhesive is safe to use? Thanks
