So after I lock my car my passenger side city light stays on for about 45 seconds to a minute. As soon as I press any button on the remote even trunk opener, the light will come on for the minute and go out after. What could be triggering this? Some module staying awake?

When I saw this occur I brought up the voltage display in the cluster to check my voltage. I saw 12.2-12.3 before start and 14.1 on cold start then settles to 13.8 after a bit. This seems normal to me, is it? The one issue is when in stand still in traffic for 15-20 mins my voltage dips down to 13.5 when I start to drive again then jumps from 13.6-13.8 for the rest of my drive. This I'm thinking is not normal? Alternator was replaced 3 yrs ago with the batteries as well.

Both my city lights stay on for a while after locking the car, along with other lights too, tail, license plate, under the door mirrors to name a few. It's normal, but definitely not normal for only one of yours to stay on. Are you sure one isn't burnt out?

What? have you tried setting your headlight switch to the "0" position when you leave the car?

Lol yes I know about the auto setting. My headlights are turned off or to "0". And no lights are burned out.. its weird just started happening

is your turn signal lever still engaged when you switch the car off? I know in the VW Golf this leaves the corrosponding city light on.

I know my 911 does that too.....have to check but don't think the E55 works that way.

OP mine does the exact same thing except it's the driver side city light I always thought it was kinda weird.

kompressorfed

Really that's weird. Has it always done this and how long has this been going on? Mine just started to happen last week.

Mine did this once and I fiddled with the light switch switching it back and forth off auto... never happened since that iv noticed.

I just bought a 2012 cls 63. When the car is off and my light is turned to P or parked instead of auto, I get out and lock the car and the passenger side LED parking light stays on. I'm starting to think its a short or wiring issue, this is so crazy. Someone has to know something....

I had service B0 done 2 weeks ago on a 2010 GLK350 and told the garage to check the fuse for the cig lighter(was not working) and they replaced the fuse and a few days after that service, saw the rear passenger light came on in the garage one evening, started the car and off and the light went off.


A few day later, the passenger headlamp came on when parked, the light switch was at 0, turned it to A but it still stayed on, turned it to 0, and it went off

This morning my wife couldnt start the car, my guess was that the freaking headlamp stayed on for the night, had to boost it, now car is in the garage
to be checked out.

Searched this site and it seems replacing the light switch resolved the issue by some posters, dont mind paying for this repair if it is the culprit.

Will post the outcome once I have the answer.

oh.. forgot to ask you, if you had this fix?

Yep, mine does this too. Have to set the light selector to "0" and jiggle the damned thing. The problems seems to be crap quality light mode selector.
