Howdy Folks:
Are any of you as disappointed as I am with the gas cap holder on the fill flap. No matter how careful I try to be, I seem to dislodge it when refilling, so that it falls on the exterior surface just below the flap. If I keep this up, I'm sure to chip the paint. Yeah, I could take matters into my own hands, but has anyone mentioned it to their dealer?

I had the same problem, until I cut the cord. Not I just put it on the roof when I fill up.

I played with that also, I finally found a way to put it in the holder that keeps it in place securely. I still don’t like it and you do have to force it in there pretty good.

In Jersey, by law you have full service only at the pumps. I haven't paid attention, but I bet the attendant just lets it dangle and scrape the paint

It plain sucks

I think it is poorly designed also. In addition, the cord is twisted to an almost unusable lenght on my car. I don't know why they did not use the same setup as on my E-class as that one works just fine.

Interesting the things you don't realize everyone is experiencing. I've had problems with the gas cap holder too, and I just sort of push it in. Once when I went to Exxon the pump handle had that large advertising gizmo at the top and I almost couldn't fit the nozzle into the tank w/ the cap sitting there. I've learned how to position the cord when I close it. A couple of times, it twisted and caught hold of the door which made it hard to open next time.

Put it in BACKWARDS with the handle pointing to the front of the car. It does't make sense, but it fits securely that way.

I insert the cap into the holder with the handle pointing to the front of the car (not the flap), with the cord protruding from the holder, pointing toward the outer edge of the flap. In this manner the cap goes into the slot easily and is held there securely. Yes, you can dislodge it with the gas filler nozzle, but I've learned not to jostle it.

It works just like my previous car (a Ford), so as with any other car it's just a learning curve issue for me.

I finally realized what I've been doing wrong trying to put the gas cap into the holder! Last two times I gassed up, I figured it out. What I didn't realize is that the holder is set at an angle. I was trying to push the cap into the holder parallel with the open gas tank door. If you place the cap, handle to the right (toward front of car) and angle the cap so the rear is further to the right (front slightly to the left), it slips right in! It isn't held in tightly, but at least I don't have to force it now.

The owners manual has a picture of the cap placement in the flap. (No wonder it's nearly 400 pages long.) I don't have the page number handy, though.

Oh, Ryan

In the C230 manual, the picture is on page 278. I just tried it, and it works great.

is this what you guys are having trouble with?

Next time you might want to try saving the picture as a JPEG so it isn't so big...

Today i went to the gas station to fill up today and right as i finished and tried to put the gas cap on it did not go. i tried turning all different ways but it did not lay flat i was at the gas pump for about 25min. trying to get it on a people were looking at me like its a rent a car and i dont know how to put gas in. After a while a person who works at the gas station came out and asked if i needed help and i showed him what was wrong and he tried putting it on and he could not do it eaither. so he said thats what u get for waisting you money on a Mercedes. So i said thanks for your help can u please leave. Well anyway he left and i was still stuck with the gas cap not going on so i decided to just drive home as is. I thought the Check Engine light would go on but it didn't. I finally got home and tried fixing it and it still did not go. So i called 1-800-for-mercedes and spoke to a road side assistance person. He told me this happens all the time, he said i should get a pair of pliers and pick up the 2 silver latches on the inside and put those latches on the white plastic peice. Mine looked like a cross like + that and they were supose to be on top of eachother in a straight line like --- that. If u dont know what i am talking about just go look on yours u will see the metal peices on top of the white plastic peice. Which is the correct way. So after a while of trying to do it i finally got it and put it back on and now it works fine. I am just wondering why this happened?? its not like i pulled it hard or different than usual it was just a normal way of opening your gas cap. Well i am glad its fixed and i did not have to bring it to the dealer or anything but i was just curious did this ever happen to any of you??

FrankW

looks like its not ur fault...i'm thinking maybe its cause by the gas nozzel from the station and it some how mess it up...because i know some of the stations near where i lives have some of the most messed up gas nozzel i hav ever seen...once it had actually stuck to my dad's fun car 1.8T beetle.

To which you should've replied "At least I don't work at a gas station buddy! HAHAHAHA".

I hate jeleous "haters".

I was filling up gas at a mobil station near my house yesterday and when the tank was full i tried to put my gas cap back...but it wouldn't go back in...I took a look at the gas cap and realize that the two metal prongs were not in sync with the white plastic under it...anyhow I rotated the plastic so that the two prongs were lifted up a bit enough that it fit back....I don't think it has anything to do with the stations gas nozzle because it doesn't even touch the cap...its probably cuz I twisted it and it somehow got caught and twisted back the opposite direction releasing the locking mechanism in the cap...no big problem...took me about a couple minutes to realize what happened...I felt like a retard though...hehe

BlackC230Coupe

yea i should have said that but i was so pissed i did not even realize i just wanted it fixed. Maybe i will go back oneday and say something.

i felt pretty stuipid to.

Fuzzo

It hasn't happened to me ....yet... but thanks for the info on what to do if this ever does happen....

Mach430

I did this once. The cause is if you turn the gas cap before it is completely on, it will push the 2 metal prongs the wrong direction (or something like that...). It must happen relatively frequently, because my service advisor had a tool that is used only to fix this problem, sitting on his desk when I arrived.

BlackC230Coupe

i would like that tool, but for now i just put a pair of pliers in my car just incase it happens again.

What the hell is going on. I went to fill up gas in the morning, so I unscrew the cap okay. After I am done, i try to close the cap and no Avail. I am like WTF, so i attempt for the next 2-3 minutes while people are looking at me like What the hell.

So I just took it off the plastic wire piece, and put it in the car, and drove with out a fuel cap. Then the error message came on.

My question is what's wrong?. Has this happend to anyone.?
Will this do damage to my car?

Since my dealer is far away, i just dont want to drive all the way there.?

bobbyrab

Well, same thing happened to me with my 2002 C320 and I felt like an idiot too, but I called tel-aid and they told me to re-align the white plastic wing on the inside of the fuel cap to the metal wing, and, sun of a gun, it worked!

Hope that helps. It is a ridiculous thing to happen.

Thanks I will try that
