Where is the emergency trunk release on 1992 merceds benz 300e

SOURCE: My trunk release button on my Mercedes Benz C230

I have the same intermittent problem on my C230 in that the trunk lid switch will not open the trunk lid from inside. If you pull it the least bit hard, the little plastic switch button breaks off and you have to replace the whole unit. Mine has been replaced twice and five months later it is now happening again. One of the tech's at Mercedes happen to say in passing that the contacts may have a problem in the hot weather and it was acting up during several heat spells. Problem is the assembly is $742.00 installed each time and Mercedes says they only warranty the replacement from the date of the original installation instead of a new warranty on the new part. I am currently fighting Mercedes of America over this as they seem to have a problem with the switch and will not admit it. Everything is so expensive on a Mercedes.

Emergency operation of rear lid
If the rear lid cannot be opened with the radio
remote control (e.g., if the battery of the remote
control is dead), the emergency operation must
be performed:
1. Unlock and open the driver's door with the
vehicle key.
2. Switch on the ignition so that the alarm system
will not be triggered.
3. Check if the TAILGATE function is activated in
the multi-purpose display of the instrument
panel.
Please observe the chapter “TAILGATE” on
Page 119.
4. Press the central locking button in the armrest.
The rear lid is now unlocked and can be opened
with the unlocking handle

The check engine light is on for a reason. You need to pull the error codes, and resolve all of the issues indicated. Then the light will go off.

If a condition were to happen, and be intermittent, the light would go out....But your description appears to have a fault condition detected. It is better and less expensive to fix the issue(s).

If the fuse is okay, check to see that the latch is not bound in some way, and that it is properly lubricated. A dry latch sometimes will not release.

Hi, yes there is. To release the trunk - look on the centre console, just rearward of the front seats and you will notice a separate rectangular section in the plastic, if you lift this out you will find a cable release for the trunk underneath. To open the fuel filler cap manually, look inside the car just behind the rear light on the same side as the fuel filler and you will notice a flap in the interior trim, which is to allow access to the rear lamp. Open this and then looking towards the top you should see a loop of orange plastic - pull this towards the rear of the car to release the fuel filler.
Hope that helps Matt..
