All w204's have the flashing green light in the trunk which prevents you from being able to lock people in the trunk, by giving the person in the trunk a highly visible escape button that never stops blinking Green, EVEN WHEN YOUR CAR IS LOCKED AND SITS IDLE FOR DAYS...

It NEVER stops blinking green... I found this when I locked the car and had my optional split seats in the folded down position... When I was walking out of the garage I saw a light inside that I at first thought was an interior light that wasn't going off..

Not a big deal at all to me, as I actually think its a pretty good safety feature in case a kid locks themselves in trunk... But I was just wondering, if I leave on vacation for 2 months and leave my car parked in the garage... Will the battery be dead when i get back because of this light that never goes off?

What do you guys think... My guess is no, because it blinks for too short a time period and seems like it would take a year to kill your battery...

Just board at work and wanted to start a worthless thread pretty much

Did you come back some time later and recheck? NEVER is a strong word when one is referencing 1 data point.

This very important subject came up long ago. So, I did a little test to determine how long it takes for the light to stop flashing which was posted at that time..

Just for you, I'm running that test again and will post the result very soon. In the meantime, get back to work.

6-pack and pizza time.

yes, I came back in about 35 minutes and it was still flashing...

maybe ill come back overnight and see if it still is flashing in the morning..

I think it's supposed to stay on for 45 mins.

RLE

OK OK OK. I got distracted and at three hour point it was out. So I started over.

The manual for the SL says how long it will stay on. I though it was 30 min. I'm too ripped on Laphroaig 15 yr to check right now.

every mercedes sedan has this. no one has battery drained because of this. if your power seat module fails now that will drain your battery within a day.

The internal resistence of the battery will discharge it far sooner than that blinking light would, even if left on all the time.

You can now worry about something else/

I left my car sitting the entire summer without unhooking the battery. 95 days to be more specific.

It started without a problem .

One interesting thing was that my quickpark sensors were not working at all, but after running the car for a couple of miles they started working fine. I took the car to the dealer for the A service (and to have every checked after sitting for so long). I told my SA about the problem with the quickpark not working at first. She told me that when the car senses low battery, it goes into a "sleeping stage" where it shuts off all the electronics that are not vital; therefore after the battery got some charge it reactivated them.

This sound like BS to me, specially since I opened the car through the remote on the key before starting it. But what is not BS is that this car will last veeeery long sitting still before the battery dies (or maybe it is the OEM batter that it is excellent quality).

Looks like it goes out somewhere between 45 and 60 minutes and that's all the time I'm wasting on this.

My car sits for weeks and months at-a-time and it starts right up.

assuming its an LED, it could probably go for years.

the answer is on your manual
