W203 CENTRAL LOCKING DOES NOT WORK FROM FAR !
Hi,
I have a 2001 model CDI 200 and my central locking does not work from far ! Ive changed the remote key batteries but still it opens only when i point it at a foots distance from the drivers door only ! Even the cars radio seems to have developed a poor radio signal ! can someone tell me what the problem is ?? i assume that the car's radio antena reception is weak. Can someone tell me where the antena goes after it leaves the head unit behind the dash ? Is there a power antena signal booster hidden somnewhere ?? This is driving me mad !!

Me too
See my post "Intermittent key remote tale of intrigue and mystery " within a few minutes of your post, I tinted my windows years ago, I can't see that being the issue.

W203 CENTRAL LOCKING DOES NOT WORK FROM FAR !
Thats right ! If the problem is because of tinting the glass, then, it should work with the doors open and no obstructions at all ! i tried that too as i had installed expensive VKool tints that cost me a pack !! But no luck, it is still the same.
Another funny thing is that it works from a larger distance(say 5feet ) when i lock the car after a drive. It looks like as though something got `charged' after the drive. Before the drive, it works only at 1 foot distance.
Is there someone who can throw some more light on the problem ?

Cost of tints has nothing to do with it. You can't put a metallic tint on the rear window of a Benz. You need to find out if VCool tints are metallic.

Then as I said in the other thread.
Check connection at sticky pad TDC rear window under the headliner. (no need to remove liner)
Check earth/ground on antenna amp
Check that antenna amp has not blown - They do quite often & have been redesigned many times.
You say your radio reception is awful - It uses the same RF antenna embedded in the rear glass. You have an antenna circuit problem. Do checks above.
Good luck

According to data on the internet VKool tints are metallic - no good for the rear window of a Benz. You will have to remove it and fit a non metallic tint on the rear window. You can leave it on the other windows

Hi Glyn !
Thanks for the inputs. Will check with the Vcool dealer if the tints are metallic. my guess is that they should be.... Will also check out the rear RF antenna booster amp (any idea where it is located at the rear ?) ?
Is there a schematic diagram available to show the location of the amy and RF antenna wiring for the cdi 200 ?
kalim.

wait for a really sunny day. let the rear of the car get the direct sun light after noon for a few hours. That will soften the sticky tape used to glue the amp to the rear glass. You will need some kind of a plastic wedge to carefully separate the amp from the glass. Do not insert the wedge on the places where the tracks on the glass go behind the amp as there are sensitive contact parts in that area. It is kind of heard to reuse the old sticky tape. you will need to make sure that all of the contact rubber parts are in place when mounting it back. Check all else such as fuse #8 and others related to central locking system.

Which part goes bad? A, or something in the connections in B?
And how can we test them to see if they are bad? Is there a way to do it with a multimeter?

W203 slightly modified
If your car was painted and left in the oven too long then the rubber tape holding the antenna all the way across the rear window had started to let go. The gap between the glass and antenna causes the pickup to detach and the radio unlock starts to fail.
Get a clean rag. Make it into a ball. Press up on trim along rear of glass along top edge. If it works then it is the above problem.
If the rear fuse box is not working well. Same problem.
You should also have weak radio reception.

If this issue crops up right after tinting but you know the tint isn't metallic, have a look at outer edges of tint. I have done a few BASIC tint jobs and the final part is trimming the edges with a really sharp exacto type knife. Would be VERY easy to disect crucial connections in an attempt to have perfect edges.

I had the same problem on my BMW (E60) and I replaced the diversity amplifier tucked under rear roof liner between 3rd brake light and C-pillar. That fixed the problem.

New Antenna still blown fuses
Hello,
Thank you all for the insight into this problem. I assume my problem was a failed antenna as well b/c the fuse is blown and a new immediately goes once installed. So I went ahead a bought a new antenna, installed it and same issue exist, fuse goes.
For further testing I disconnected the new antenna completely put in a fuse and it blows right away.
Does anyone have anymore ideas already spent the cash on a new antenna so I am kinda committed to fix this ...
FYI: c230 2005 sedan
