Last night I bought a AC Delco battery for my '02 C240 because the one that came with my car died on me.

The car started great, my bi-xenons turned on but I got a message that says "ESP not programmed - visit workstation". This morning I turned on the car and the ESP is working now.

Here's my problem. I have no audio. In radio I get no sound, when I hit CD it says "No Changer", and in TEL "No Phone". Is there something that I need to get programed. Can I do it myself? I hope that I have to take my car to the dealer for them to rape me again.

Thanks in advance.

Theres is Code you have 2 get from the dealer. its a secerety measure so no 1 can steel it. so just try to drive 2 the dealer and get the code

Actually right before I left the library to go to class that crossed my mind.
I'll call the dealer right after I leave class.

Thanks again

Faced with a bad battery, I'd call roadside service. They bring the correct battery, hook it up, and attend to reprogramming the items that "lost their mind" when power was lost.

It only costs a couple of dollars more than a second class battery from an auto parts store, and your back up and running. A Die Hard is almost $ 100, and roadside gets $ 115.

There is a list of things for you to do when a battery is replaced to 'sync' various systems (like ESP!).....it's in your owner's manual. Your car uses a 100AH battery, what did you put in? I don't think AC Delco sells a 100AH car battery, I looked for one (want a gel filled) in anticipation of my battery going out. Noone sells a 100AH battery that I could find except MB. Moviela is right when it comes to the C class 100AH battery....call roadside assistance. I wonder why they need such a hefty battery?

RTFM!!!

Look for the radio code in the folder containing the owner's manuals. Also, read same for the correct method to resync everything after disconnecting the battery.

I had a friend who was stranded with his '02 E320 at a parking because he had forgotten to turn off his headlight on a cloudy day earlier this year. He called the MB roadiside assistance and the old battery was swapped out with a new one. Free of charge!!

1) There is no Radio code needed on these cars. The unit gets its signal from the can.
2) The place where a code might be found is on the VMI; read 1) as it is not needed.

Don't they have the same type of anti-theft radio as the 210 or are you saying that removng the battery won't cause this problem?

I got it working. I disconnected the battery a couple of times and everything it back to normal.

I called both dealers Mercedes of North Miami and Mercedes of Pembroke Pines earlier this morning and they said that I needed to get an appoitment. One of them said that I fried the radio and software and it would be about $600 to check .

Anywho I got it solved. Thanks again to everyone with your suggestions.

Go easy on those power up cycles. You could do about $2000 damage doing that.

I can't speak to the W210. But I do know that the W203 doesn't need the Code.

Why is that?? Do we need some special method to reconecting the battery?? Whenever i need to disconect the battery i only remove the negative/grounding terminal, is that ok??

For one there is a huge risk of blowing the rear SAM (fuse box) which will then also blow the rear stop lamps, keylock and several other things.

To safely install a new battery you are now supposed to remove the rear trunk lining on the left side and unplug the power INTO the rear SAM so that it does not draw power at any time during the power up process.

I have heard of people getting massive phantom problems after doing a battery change very carefully.

I have read on this subject and spoken to several people in the workshops. There is inherent risk in changing a battery without precautions. The BEST precaution according to current thinking is to pull the rear SAM power cord and I must admit that it seems to work well.

I have also heard of some people blowing the front SAM too. But that appears to be unlikely. The advice to just pull the power a few times is about as risky as it gets. The worst part is that it may take a few weeks for the signs to show up.

The mechanics have to do this every day. The stories they tell are very informative.

Thanks for that info!!! now will i need to do that if i'm going to disconnect only, not replacing the battery??

So the cost for the new batt is $115, is that including tax? I just wanna make sure that I wont get rip off. My car's batt died just a couple mins ago and I will call the MB Road Assistance in the next 3-4 hours (got something to do).

Anyone can confirm about the price? Also, can anyone tell me what other thing I should pay attention when the MB guy come to change the batt?

Just out of curiosity, How long approx. did you guy wait until the MB guy show up?

Thanks in advance
