My car has been sitting for over a month now with no power at all... Even my car now is so low because I guess the "air" from the air shocks gone so I desperately need to fix my car.

If there's no power to the car at all, it's either the battery or a main fuse... even with a completely destroyed BCM parts of the vehicle would still work. You may need to send it in if you can't find the source, a diagnostic fee is cheaper than a lot of fixes on these cars

You know I think it's the main fuse because when I put the battery in I don't get any spark at all its like the car doesn't know that there's a battery. Anyways, where can I find the main fuse? That's the first thing that I wanted to check but I don't have a fuse diagram on my car. Thanks

Thank you very much! Just checked out the fuse diagram and made copies already. Last question, probably a stupid question for you but which one is the power source fuse or better yet which one should I check? Many thanks again!!!

All of them, lol. It's important that your systems are functioning correctly, you should never have a burned out fuse.
For this particular problem, I would start with the fuses with the highest amperage and work your way down.

That's actu the first thing I did, checked all the fuses and all of them were good. But the relays I never did coz I don't really know how to tell if it's still good or not but I will do it again and double check every single fuse and hopefully will find something. If none, can I remove the bcm from the car and take it to a star diagnostic shop? Or do I have to have the car towed to the MB dealership to have it fix... It's been more than a month now that my car is not running... I'm getting desperate already!

Like I said, there are things in the car that are not controlled by the BCM, so if those are not getting power... you have another problem.

Hi guys, just want to tell you that I finally got my car started and running!!! Checked all the fuses, then went to the dealership and got a new battery.. Installed it and boom! Got power and everything looks AOK. Didn't even have to reset anything... Just the clock.
Anyways, thanks for all the help and support... You guys are the best! Now my next project is to lower my car using the star diagnostics I read on one of the post here...it'll save me a lot of money instead of buying springs to drop my car.

Here ya go. This is a power wire... hook the positive side of your jump box or second battery to this and the negative side to a ground. I usually use one of the passenger seat bolts because I have skinny extenders on my jump box leads, but you can use anything on the chassis.

Otherwise, can someone post a picture of the place that I can jump it from behind the SAM? I don't know where the SAM is located so I don't know where to look.

I had no luck at all finding the positive in my RHD car - the wiring is different. The only way I have been able to start her (twice now) has been under the windscreen wipers as shown earlier in this thread if I remember rightly...

Opening the trunk is done with the little key on the key. I had this same issue a couple of weeks back and the damn key just wasn't working because people told me to turn anti clockwise when in fact turning it clockwise while pulling on the lever is what got it done. You went through alot of trouble to take out the wipers and all...
PS. I've jumped the car from the battery and nothing bad has happened so not sure why you all are going to the trouble of jumping it from the front.

The trunk key has a very specific way to be used, and "Fiddling" with it is not likely to open the trunk.
If I recall correctly you turn the key all the way (I forget the direction) and then while holding the key you pull the handle.
Given that without instructions it took me about 10 minuets to figure this out, I can see how some people believe it is either "broken" or works randomly.

Umm I'm not too sure about you people that take 10 minutes to open the trunk with the backup key as it is actually quite simple. I have done this many times both before and after my episode with the flat battery WHICH NECESSITATED THE STEPS LISTED EARLIER IN THIS THREAD TO SOLVE. In fact I think ALL possible solutions to this problem have already been covered which is pretty obvious when taking the time to read.

Then you say "Hmmm, that was weird, it did not work"
So you turn it one way and back and try the handle then the other way and back and try the handle. And say "I sure hope something is not broken".
So out of desperation, you figure maybe you need to hold the handle while turning the key, and still no joy.
So in an act of complete frustration you start turning the key while pulling the handle hoping to feel one or the other catch the mechanism, and eventually you get the key turned and held the right way as you pull the handle and Voilà!
(and if you are like me, you pay attention to what made it work and double check you can do it again) (Or you just assume it is a maybe thing)
