Hi everyone! I am new to this forum and this is my first post. I am facing a strange problem! Recently I bought a 2002 sport version MB E-Class Avantgarde (W211) E220 CDi Sedan 110KW with 229000 km (approx. 142300 miles) on clock.

The previous owner (an old guy in his 70s) did mentioned that the Radio as well as the cassette/CD player is not working. There were no lights whatsoever in the unit, as shown in the picture!



I thought it's not a big deal and would get it fixed but now (after every possible effort on my part) I am now getting tired of driving this nice old car without any music.:doh:

Last month, I took the car to a local garage and got a manual check-up of all fuses, load test, voltage, battery, etc. Everything seems to be fine except the weak system battery (11.0V) and I guess the Radio itself, which he said might be faulty and needs to be replaced. The auxiliary battery was ok with 12.5 voltage.



Earlier this month, I bought this replacement Radio with part no. A211 820 08 79 (Model. CK1211). Original Audio APS 20 with Cassette Tape Slot (Not CD Slot)!



The previous one was also the same, but with this Serial No. AL 1211 2 04 24576 (looks like it was replaced too). Before fitting the Radio, my battery started showing signs of complete weakness with shutdown of consumer devices and Red battery message - (Visit workshop) so I also replaced my old battery with this one: Yuasa YBX5019 Capacity 20hr (Ah): 100 with CCA EN1 (Amps): 900.

After installing the Battery and the Radio, one thing did changed! After inserting the key, I see this message for few seconds: "Audio Searching" and then both in the Radio display and Instrument Cluster I see a dashed horizontal line. ----- . (As shown in the attached photos).




Moreover, after pressing the silver "open/eject" button I am still unable to open the cassette/CD player (previously all the functions on the centre console switch panel switch block were/are working normally "except the cassette/CD opener" or "silver eject button").



Members, I need your kind help to sort out this problem. Does it need any programming/software/firmware update or any other part replacement? Can it be that the cassette/CD player isn't talking to the processor? I am on a tight budget, so please don't scare the sh*t out of me by saying I may need to spend a fortune, €£€£€£€, just because I bought this Mersu.

Also, if anybody has faced exact same issue kindly share your experience and help me solve this problem, so I can find the root cause.

HELLO...please help me! I wanna hear some fking music!

If anybody's out there, anybody -- please, help!

 

Looks like it's a useless forum!

 

Still, no any feedback in reply to my thread. How sad!

 

SHAME, SHAME, SHAME ON YOU MBWORLD.ORG!

within last 3 months, over 350 hits but not a single reply?

Is this a GHOST forum where dead people need ***** to reply? Did I asked something impossible without explaining myself in detail? What a waste!

ADMIN...if you are out there reading...just change this so-called MB-WORLD and rename it to MB-TRASH forum!

And those who feel itchiness in their **** after reading this post, just do yourself a favor..."Don't reply!"

OVER AND OUT!

 

Not sure if my problem is the same as yours. But my Audio 50 system occasionally goes out. It seems to happen after driving in hot weather and using the AC a lot. Anyway, the temporary solution is to remove fuse #6 (in the trunk) and reinstall it.

I have a 2003 E320...

 

Same here for my friends car. This began after a jump start. All fuses have been checked & are good. My A6 had a fuse in the back of the radio that blew out everytime I gave somebody a jump. Thus, I has to pull the radio more than once...
Otherwise it was painful w/o tunes...
Did you ever solve this problem???

550CLS & 986

 

Not sure if this is your problem, but some radios of that vintage were intended to brick themselves if they sensed removal from the vehicle (as in theft). If the original radio's power connections were removed for longer than an allowable interval, this might have happened. The last radio like this I owned required a PIN code to unlock it. Not sure who can help restore it, but try an MB dealership.
