Drove it all weekend and it was running fine. Then today drove to the gas station, went inside for a few mins to get some stuff, came out and car just wont start. I do have power for the radio but none for the windows and ignition. Any ideas??

Tried to jump start but yeah didnt work...i dont think batt is the problem. Getting it tow to my mechanic tomorrow.

A burnt fuse maybe?
Have you opened the trunk and checked the fuse box?

iamtodd

Wheres the diagram for the box? I couldnt find it on the manual. I did look at it but i guess not hard enough

Possible the connection to the battery are loose. Move the ground and power wire around a bit see if it works

Could be a bad ignition module, seen a few go bad. Take her in

If your battery drops below 10.5 volts the computer wont allow it to crank the engine over... there will still be lots of power left to run the radio... recently have you noticed any of your preset features loosing there memory?

You can go in dyno mode and check the voltage on your battery.

However if you tried to jump it and that didn't work something else might be wrong it should start with a jump.

Jumping our cars off anything other then another V8 is a painful experience. If it was a V8, well then I do not know.

I know when I got back from a business trip my car was dead at the airport, radio worked, but nothing else did (has to use the blade to just unlock it, the remote did not work).

When assistance showed up (I told them I had a V8), they had a V6 pickup truck with one of those jumper packs that did nothing. The guy ended up hooking up regular jumper cables to his truck, and sat revving the engine for 20 or 30 minutes before I was able to crank the engine and start it (also.. the noise it made in the covered garage was insane when it did start up...)

LOL...you haven't lived till you've heard a true cold start in a parking garage with LT headers....

So i went back this morning with the tow truck, the guy said the same thing if i tried to jump start with just a regular car. I said yes, he said let him try with his truck and that it has a lot more juice than a regular car. Well still didn't work. Radio works but none of the lights or anything else is working. It's in the shop right now. They will scan it and see what the problem is. i'm hoping it's nothing crazy, i'm out of warranty : \

Could be as simple as the battery in the key as well

CoolBDPhenom03

Almost forgot about that possibility. OP, have you tried a spare key?

jvanbrecht

It won't be the key, as the OP noted that the radio turns on, which means the key authenticated to the vehicle just fine. It is not a matter of varying levels of current in the key, its digital, either it works, or it won't. Not half and half.

Sounds like a bad ignition module.. Hope u get it fixed at low cost! And all this issues I've been reading on the forum lately makes me think again about buying the xtended warranty.

iamtodd

So my mechanic said it's electric steering lock module went bad. anyone heard of this issue? He called the dealership but they won't sell it to him due to some "theft" reasoning? so i guess i'm going to call and try...but i'm curious if it's something i can purchase myself online?

It's probably the same issue I experienced.

If a dealership isn't willing to sell it, I somehow doubt you'll find it online. You could try asking MB for a part #. If one exists, you could try Parts.com but then you'd have to wait. . Can't you show proof of ownership and registration? Or are they saying that so you have to go to the dealership?

iamtodd

Parts is roughly $530.

Does anyone know if you can purchase this online somewhere? or do i have to buy it from the dealer?

olszowa12

That sounds about right.

Have you tried PARTS.COM ?

jvanbrecht

I suspect with the ignition parts, no matter who installs it, your going to have to take it to MB to code the keys. Otherwise, I do not see why they would not sell the part to you.

I had the same issue covered under warranty and I have a long thread about it in here somewhere. The SA said it was a very difficult job to replace the module because of the location in the steering column. They also told me that it affects MANY cars and not just C63's. The road side assistance driver said he had seen about a dozen cars with the same problem. You might be able to appeal for coverage if this is a documented chronic problem. Look up my thread because I posted info from the repair order.

iamtodd

Found your thread. Now i understand that certain parts you have to buy from mercedes/dealers i'm fine with that. The thing that gets me is they will only sell me the part if i get the car fix there. I do not have warranty so i do not want to go through them. My mechanic knew bout the problem he knows how to fix it. In the past they would sell you the orange key which will let you reset the code or whatever in your keyfob. then you return the orange key for the credit back.

Now how do i go about doing the appeal for coverage thing? any ideas where i can start?

jvanbrecht

Do you have the part number, I can check with my dealer (I have a good relationship with the parts dep manager) in Annapolis, they also do mail order via getmercedesparts.com. They have a bunch of ignition parts listed on the web site when you search for the keyword ignition...

iamtodd

Well the car is with them now. So i'll just bend over and take it this time. I don't think the part is the problem but the so called "orange key" where they program it into your keyfob might be the thing.

Anyways i called MBUSA and asked bout an appeal for coverage and what i need to do. lets just say she wasn't very pleasant to talk with. Basically they said they will call me back. So yeah i'm not sure if that will go anywhere.

Had the same problem, after owning the car for around a month, a let down. They had to replace the whole thing, which they imported from Germany, (I'm in South Africa)after waiting 3 days, took them another 2 days to code it or something. Quite annoying, is a common problem, which they don't seem to have fixed. Call out guy said happens often on the c class but he hasn't seen it on a amg, I was the first.
