Mercedes SL 280

The boot and fuel cap wont unlock

    Fuel cap will not unlock on 2003 Mercedes E 320. Didn't even know it locked! One day, when I removed the cap to add fuel, I could not get the cap back on. There are two metal pieces sticking out on either side of the cap that keep me from completely replacing the cap. Of course, engine light is on now, as well as notification that I need to replace fuel cap.

Hello, I'm not sure if you are talking about the lid that you have to open to get to the fuel filler cap or the cap itself. If it's the fuel filler cap that you are talking about, you will need to take a pair of channel locks or equivalent and grab the two metal pieces that are about 3/8" wide, hold the cap with one hand and turn the pliers with the other until it snaps back on top of the ex centric.
If it's the actual lid that won't open, it is a vacuum problem. You can try to leave the car running, then work your locking system back and forth with the key in the drivers door. That should get the trunk unlocked. If you can get the trunk open, look to the upper right in your trunk and should see a round pull knob, pull it and your lid will open.
I hope this helps.

Hi,
The early 300 SL suffered from dodgy HT leads and spark plugs if not regularly maintained, the problem with Mercedes Benz though is that the cars have so many features that it is almost impossible to diagnose without seeing the car. Some things to try (in this order) are : - Spark plugs, Ht leads, remove and clean Distributer Cap, replacement of HFM sensor (common fault), if none of these help then faults have been known in throttle valves and fuel pumps/filters

Happy fault finding
