Hello,

I have problem with my 06 mb cls 320cdi. Left-hand number plate lamp isnt working. It keeps blinking after 5 seconds..I have changed the lamp but the fault is still there. I changed a couple mounths ago and but there LED-s.
When i took both lamps out suddenly left-hand lamp work and the other, right-hand lamp kept blinking. LED´s worked correctly before..2 weeks.

Any suggentions? Do i need to replace the SAM module or is there anything to check?

SO now both licence plate lights are LEDs right ? If so did you replace just an LED bulb or the whole light assembly ? Look at the pictures.
Do you have any other lights on your CLS replaced with LED ?

Do you have this


or this

madisvaltu

exactly the firsts..I changed the bulbs. front park lamps are also LED and they work correclty.

GuestFromTampa

Problem solved then, you have too many cheap LEDs ive had exact same problem .so you really have 2 option -replace park lamps with quality LEDs like these http://www.aznoptics.com/index.php?m...&products_id=8 or i am selling a pair becouse i didnt like it https://mbworld.org/forums/mobile-el...ptics-com.html
or option two will be purchasing quality LED licence plate lights like picture #2 , they are not that expensive , i think i paid $40 or so...

But over 2 weeks both leds (front and rear) worked correctly...who to explain this? Today i tried another new leds to the licence plate number and they didnt work too..

I think it is car ECU adapting or something because LEDs drawing less power then regular light bulbs...
I am just sharing my own experiance-ive had same problem and i found solution that worked for me

Ok, i will try ugly yellow lamps and will write, if it helped or not.

GuestFromTampa

It wont be instant, ECU will have to adapt again. Now Yellow Lamp you said are we taling about the turn signal or parking light ?
Perhaps i am wrong but i tought

GuestFromTampa

I bought these

But can not the old ones out cos the chrome trim on the boot lid is stopping them from coming out

What a stupid idea, why not made the gap slightly bigger, and to take the chrome trim off is impossible cos it's stuck on!!

Unfortunately this is the part that ***** from IJDMTOY.com dont tell you and then they deleted my review even tough i re-left it 5 times .
Anyways it just takes longer , you will need to remove 2 screws and then there is a double sided tape that holds boot lid in place. I used old credit card to separate the lid from the trunk. Taking off old tape off the plastic lid that is a real PITA. Took me like an hour. Then you have to use new doublesided tape, i used 3M . Not that hard.
this is what it looks like when you done
