I've learned to live with it. The smell goes away after about an hr.
so my gtr is fine but my GLS makes this smell. My old gl didnít and they both have M157 engine. Iím not expecting resolution by the way as Iím sure I will get similar responses from dealer.

I also smell gas/burnt oil on my 2018 GTS when I park it in garage, it only has 500 miles on it. It is always after a drive and last couple of hours.

My 2016 GTS started making the smell when it got to about 10K miles. I took it to MB dealer. They kept the car for 2 days and said they couldn’t find anything wrong with it.

Has anyone found any answers or resolution for this?

Mine had the same burnt oil smell shortly after picking the car up, which I think was caused by the oil level being slightly too high (it threw an oil level high warning), but after having put 400ish miles on since they did a fresh change to fix it, it's pretty much gone.

Can you tell at all what side or where smell is coming from? There was a member here that had a microscopic hole in his fuel line. Or it was pinched at a clamp. They replaced line and I believe that was the end.
The smell comes from driver side front fender's vent. There was no smell until it got to about 300 miles and now it is very strong at 500 miles.

Years ago, there was a $5M class action lawsuit against MB and it's entire second generation E-Class range including AMGs related to fuel smell/leak.

When you have a chance, go to the thread I created a started of years ago titled GTS PROBLEMS AND ISSUES.
I remember some members posting about this problem.

Also, your MB dealer (Sewell?) should be able to reference this issue in the AMG database maintained in Germany along with the solution.

Best of luck in a quick resolution.

That is the area of the dry sump holding tank. Make sure that the oil level is not overfilled. In fact if you're not running the car on track, having the oil level in between the two marks is where I would shoot for.

My '15 Z06/7 was notorious for a 'burning oil' type smell when at a standstill; it couldn't be smelled when moving. Worse was when I'd just pulled off the highway and came to a red light/stop sign. One way to stop smelling it was to place the HVAC system into 'Recirc' mode, but of course you do not want to run like that the majority of the time. Smell totally resolved when I made sure the dry sump system wasn't overfilled, or was slightly below the top fill line.

I'm not saying the issue is analogous but it's something to check.

Good luck getting to the bottom of this; I know it must be aggravating.

Guys,

Thank you so much for your feedback! I made an appointment to take it to Park Place MB Tuesday. I will be sure to mention oil level and dry sump holding tank. I will report back once I get a resolution.

Please do, as I'd likely take mine in to them as well if they help you find a definitive solution.

Thank you Jerry! I found your post titled: "GTR & GTC ISSUES-OWNER POSTS ONLY PLEASE" but couldn't find the one on GTS. Any chance you could send me a link to it?

My one week old GT R has that smell too, not sure if itís me getting used to it or itís less and less strong day after. Itís definitely still there but not as noticeable as the first few days. I now have 426km only, hopefully that smell will be gone soon as mileage accumulates.

On a brand new car you could be just smelling the brake pads; DCT clutches, etc. Ďbreaking-iní. My GT R was the same. It should resolve fairly quickly. Go and drive the snot out of it once everything is warm, and really try and burnish the brakes regardless of what type they are.

Bish, I am very familiar with new car break-in smell. This is burnt oil/gas smell concentrated around Driver side front fender where the dipstick is. This is the same smell I noticed when my 2016 GTS got to about 10K miles. Hopefully I 'll report back with some resolution after my dealer visit Tuesday.

I also checked oil level and it is slightly above the minimum mark.

I was actually responding to Ďpy0413í, as I thought that his issue; (new car smells), might very well be different than yours.

We had it too and the car went back after only two days and the dealer said there is no fuel leak which is what I was concerned with. They claimed it was brake fluid and that after a while it would stop doing it. Well after two months it has gotten less significant but it still lingers for a couple of hours. I think in time it will eventually be completely gone. The main thing is that there is really nothing wrong and that is what I am convinced of. Is it a good thing? No but it's nut ruining our ownership experience.

2018 GTR - 2018 C 63S
I live in the high desert outside of Vegas. Summer temps are routinely in the 100-115 Fahrenheit range. I have 10k plus miles on my GTR. Even when filling up with gas on my way home on occasion and the car sitting in a very warm/hot garage. I've never smelled anything about what's being talked about here. And yes, I do have a sensitive schnoz when it comes to smell. My best guess is pressure from heat expansion is seeping past a connection (weakest point), evaporative canister or somewhere and causing the issue. Dealer gets the car in and it cools down. Tech may or may not take it for a quick drive. Put it up on a lift. Unless something is visibly leaking or glaring in their face. You get a verdict of normal or NPF (no problem found). This has to be a seeping issue (liquid or vapor) because of pressure from a connection somewhere. If it were an actual leak. It would be pretty obvious/evident.

It might also be possible on a tank that is less than 1/3-1/4 full that fuel expansion on a warmer day may slightly bleed off some vapor pressure once the vehicle is at a rest - just a guess. If you haven't yet. Try keeping the tank at no less than 3/4 full and see if the problem is still there or if it goes away. If it does go away there may be something defective in the EVAP (evaporative emission control system).

Impossible to be brake fluid; if they told you that find a new service dept immediately! lol (I may have told you this before). Pads can and do make a smell when the car has been driven hard, the brakes well used and the car parked up without a cool down period. Brake fluid itself is essentially without a smell; (donít try it as itís toxic as hell), although if itís leaking on something hot it might well produce a smell. But then youíd be experiencing major brake issues due to the leak.

I went back and reread all 20 pages of postings in my topic GTS PROBLEMS AND ISSUES in the Private Lounge.
http://www.mercedes-amg.com/privatel...TS-ONLY/page20

Unfortunately I didn’t find any postings about your specific problem.

There were a few related to brake fluid smell but none about gas smell in the front of the car.

If you haven’t yet you should join the Private Lounge. Many here like me move back and forth between the two sites.

Best regards.

Jerry.

No fuel smell. Just an oil smell which started after my first dealer oil change. Attributed that to some spillage that is burning off somewhere. Who knows.... this is related to a slight over-fill of the dry sump tank? Will keep a nose on it.

I'm guessing so, as I have the same issue, but no fuel smell, just burnt oil. Hoping that's all it is anyways.

This was the AMG tech that works on them. That is what my wife says they told her but nothing is leaking. They just said it will subside with time and it has but it's not completely gone.

So the tech must have misspoken then. The brake pads are bedding in as well as out-gassing the binders/adhesives in them. This causes a Ďburning brakesí type smell when new.
