Stereo code resetting??

If you're a regular reader on Benzworld, you might remember when I posted about changing my battery and resynchronizing everything. Well, after I changed my battery I needed to enter my stereo's code in order for it to work again. I didn't get around to getting the code, so a couple weeks ago my girlfriend decided to become a psychic and tried guessing the code by punching in random 4-digit numbers even though I told her not to mess with it. After 3 of her futile attempts, my stereo suddenly no longer blinked "Code _ _ _ _" but instead now says, "WAIT". I tried resetting all my electronics today by disconnecting my battery and waiting a few minutes before reconnecting it. This did not help reset my stereo at all.

Does anyone know how I can fix this, and get rid of the "WAIT" message on my stereo?? My girlfriend owes me for having to deal with this!!

I never saw that one, ask the dealer I would guess but you should not let her touch your car anyway, thats a clk forum rule

Hahaha I'm sorry I failed us by not following the benzworld protocol. I was driving while she messed with my stereo so I couldn't stop her. I will make sure something like this never happens again by having her sit in the back seat from now on, although one time she was in the back seat and tried to push down my rear headrest with force. Maybe I'll have to copy those new GTI commercials and ask her to stay behind so I can enjoy my Fast.

I might have to try TK's suggestion, although I'm kinda afraid to do something like that because I'm not the most handy with messing around with car interiors. TK, would you like to move to CA? I think one of the families in my cul-de-sac is moving out.

Hey, I can't put smileys in my posts now!

Thanks for the responses guys! I'll try Dutchbenz's recommendations tomorrow, and if I can't find any codes, I'm planning on finally calling or going to a dealer to get my code. Thanks again.

After entering the code incorrectly three times the word "WAIT" appears on the display and the radio is disabled for approx. 10 minutes . After entering the incorrect code three times again the radio is disabled for approx. 60 minutes . NOTE: The disable time runs down only with the radio switched off.

Wait a sec... Dutchbenz says to leave the radio on, but rsmcmahon says to leave it off. I've basically left my radio turned off for the past two weeks, so I'm thinking Dutchbenz is right. I'm going to try this after work today to see if it works.

punkviking, depending on your type of radio, the coding is different.


If the wrong code number has been entered and confirmed, the word "CODE" appears on the display again. After the code has been entered three times incorrectly the word "WAIT" appears on the display and the radio is disabled for approx. 10 min .

NOTE: The waiting time continues to run only when the radio is switched on.

After expiration of the waiting time the word "CODE" appears on the display again and the correct code number can be entered. After 3 more incorrect entries the radio is again disabled for 10 min . After 3 more incorrect entries (a total of 9 incorrect entries) the waiting time is increased to 60 min . After 3 more incorrect entries the radio locks up again for 60 min .

Not sure if this will help but when I got my 430 I went to the MB dealer. Once I showed them my vehicle registration w/ WIN number on it, my drivers license with an address that mathed the address on the registration and a visual confirmation of the VIN on the car that simply printed out the manufactures sheet hat had a wealth of information, including the radio code. Was worth the 15 minutes it took to stop and have them go through the confirmation process.

hey punk, I've only disconnnected my batt one time in the ml but had to dig on this. they are correct. it's part of the MB's 'alpine(?)' based radio 'anti-theft' system. you blow it twice, you have to wait 1 hour per my manual i.e you locked up the password feature--notwithstanding, disconnnect the batt again & do it all over. I would highly advise & disclaim against that w/out preconditions. this thing has WAY too many electrical components on it for you to hook up/disconnect your batt like you would a typical chevy. Radio presets aside, you'll encounter 'other' buggy issues later on--try to avoid this. dig in your car's glovebox, trunk, hell, even under the seats...look for an OEM sliver CC sized 'radio code card' It will show Code # and Serial #
For ex. mine says 5***4 for the 5 digit code and AL49**y****592 for the serial #
If you cannot find it, the others are spot on--go to dealer with vin, ID, keys in hand, & car on the lot & get it. let us know how it works out for you:)
