Stupid question about the opening next to gas cap.
I filled up my car for the first time this evening and noticed this rubber cap/gasket of some sort to the left of the gas cap. I have never seen that before on any other car so I couldn't help but wonder what it was. I Googled it and found an explanation that describes it's where the DEF (Diesel Exhaust Fluid) cap would go if it were a diesel engine vehicle.
Does this exist on any other cars? I mean I've driven many makes/models of cars and have never seen that before. I also wonder why such a soft rubber cap is used. |

It is a blank space. If it was a diesel there will be another cap over that. It is the same way on my X5.

Interesting. I'm just wondering why they use such a soft, pliable thin rubber cover on that opening as opposed to a hard plastic cap or something. Cost?

There is nothing behind there, that is a blank. If it was a diesel that rubber circle would be punched out and the rubber fitted around the fill pipe. Then a cap would be used to seal the fill pipe.

That's for the adblue tank in diesel cars.

Thanks guys. Like I said earlier, it's strange to have this really soft, ultra thin rubber cap over the opening and makes me want to poke at it. Lol.

Lol. I think I must be driving my car harder than you because I only squeezed 300 miles out of the first tank. I could've driven it an extra 20 miles or so but not worth the hassle. Yeah, I might be having more fun than you.
