E270 cdi trunk lock does not work with the remote and inside trunk lights and the number plate lighgts do not work

You should have a trunk lock cylinder in the trunk lid. Look to the right side of the license l plate by the license plate light and you will see a black plastic cover. Remove the cover to expose the lock cylinder then use your key.

Many People don't know exactly how to use the manual key attached to your remote to open the doors and trunk in case the battery is dead. All you have to do is slide the locking button in the back of your remote and pull the metal pre-cut key, then insert it in the trunk lock, turn key to the left and then push in. kawaboongha!!!

how to reset the service light on mercedes benz e270 cdi avantgarde

okay the dealer may be right,the wiring sometimes breaks from opening and closing trunk,the trunk release operates on the same power as door locks, if door locks work its not a fuse,check the wiring harness in the trunk near hinge, this system is a complex one,so if you dont see a broken wire in the harness,(you will have to untape the wiring to see every wire) have a tech check the system.

I had the same problem in me 2004 cdi e270. Check the voltage going to the battery when the car engine is on. Stedy charge of 12v should be going in to the battery, if the voltage is volitale say between 11v to 14v then it your Regulator (which is attached to the backend of the alternator). You need to change alternator and then unplug all the batteries over night and re plug them back again. The problem should go away.

There is usually a fuse box in the spare wheel compartment, there is also one under the rear ,Owner's manual indicates fuse position

i found the solution to same problem here.

it was a easy fix, broken wires in the boot a common fault with mercedes.

Your vehicle is not a Hyundai Elantra -- problem solved!

Does pushing the trunk release button make the back up lights illuminate? Has the car been serviced or wrecked before this problem? Have you been golfing and put clubs in the huge trunk. Either the ground wire for the trunk lid devices is bad or the trunk release wire (purple/orange) and the reverse lamps wire (purple/white) have been reversed.

There should be a key hole for your ignition key to fit just above the number plate along side the number plate light
