I bought the silver 2017 GTS that was in Missouri and was linked here around a month ago. I bought it without seeing it in person and finally received it Sunday. It's in great shape given it's 41k miles and even had some features that I didn't expect.

I think the lug wrench is missing. I assume it goes in the notch beside the tow hook? Anyone know a where I can get a replacement.

Every minute or so I get a slight buzz like a phone vibrate alert that I can slightly here and feel in the steering wheel. What could that be? Is it an alert and likely due to my oil overfill problem or related to the other alert I'm getting that I am 14 days overdue for my AF service?

Thanks for your help.


Just a little story on the oil issue. The person I was working with from the non Mercedes dealer sent me an email that my car was on the hauler and that an oil warning had came on and they would reimburse me for an oil change. I expected to see oil change due when I received the car, but when we started the car and drove it from the hauler and oil overfill warning came on. There is also a window sticker that says my next oil change is due in what would be 5k miles from my current mileage (no date, just mileage). So my impression is this dealer decided to change the oil and accidentally overfilled but didn't know until later. As many of you probably know, the oil level on these things is tricky. I siphoned off a half quart. Still read full on the dipstick. Siphoned off another nearly half quart for nearly a quart total and the oil read right in the middle of the range on the dipstick. But as you probably guessed, by this time the oil had cooled down. I drove it barely enough to get to operating temp and it still seems overfilled by the dipstick, maybe not by the internal display, but I did not get a warning yet. I'll siphon off another half quart before trying to check again.

 

The vibration in the steering wheel is the lane warning signal. "Lane Keeping Assist." Another feature you didn't know your car had.

Get back between the lanes!

 

Thanks. I hadn't gotten that far in the manual. Cool, I knew it said I had that feature. Pretty funny how my lane departing describes how I'm driving around pushing buttons trying to figure stuff out.

 

More than likely an oil service was performed by some body that didn't know the right procedures for the dry sump system and overfilled it.

On the oil overfill - I agree with Hendrik and this has been discussed in a few different threads on this forum.

Long story short, whoever did the oil change either didn't know the proper WIS change procedure, or did and didn't care to follow it...and that CAN include a MB dealership. Following the WIS instructions on proper oil change is NOT easy and I estimate busy shops do not have the time/patience to follow it, so they "short" it.

Bottom line - If you're overfilled after an oil change, it wasn't done correctly.

 

Don't just arbitrarily keep removing oil.

 

I agree!!
Use the proper procedure for checking oil.

 

There is no lug wrench in the GTS.

 

Hi,

MB already has a wheel change kit for the GT. Equipment code is: B12

Trunk jack support: A 197 898 01 81
Jack: A 197 580 02 18
Wheel wrench : A000 581 02 00
Wheel mounting bolt: A 204 581 00 74
Wheel chock (foldable): A203 583 00 75

But you don't have a spare wheel. There is also a suitable temporary spare wheel from MB. (There are countries, where a spare wheel is mandatory)
That is strapped into the trunk. Equipment code is: 690

Mini emergency wheel: A212 400 42 00

Also keep in mind that the wheel bolts are tightened to around 130 ft / lbs. It's no small thing with such a short wheel wrench.
Especially the opening. The risk of slipping is also high. I would rather recommend a cross wheel wrench. You need 19mm. (3/4" maybee work)

Kind regards

Stenzel

 

I am sure MBZ has the lug wrench for sale, I dont know of any GT cars for the US that have ever come with one. All the cars for these shores came with the inflator kit.

 

Hi,

I believe code B12 only exists in countries with a spare wheel requirement.
Whether it was selectable or not depends on my knowledge.

Kind regards

Thanks for all the help. I noticed today that the next oil change sticker has the name of the non Mercedes dealer where I bought the car. For sure I will not count any of this change as having been done properly. For sure this oil I'm removing is pretty black for new oil. I'll get the car in for service at the dealer next weekish. I'd like to drive it carefully a few more times to make sure I don't have any special concerns.

If by properly checking the oil level you mean using the dipstick within a few minutes of turning off a normal operating temperature engine, that's what I'm doing. I'm not having much luck getting the display fill level to work most of the time. It seems a little late to tow the car to the dealer since after the oil change the car was started and possibly driven at the dealer and by my hauler. The overfilled warning only comes on after the car hits full operating temperature now, whereas before it came on much quicker so I think I'll have it after this last half quart siphoning (I'm a boater so I'm accustomed to siphoning oil). Looks like my car will end up having been right at 2 quarts too full. Do y'all think that it is theoretically less damaging to a dry sump car to be over or under filled than a non dry sump?

I have had cars with run flats, no spare, etc and coped with it. I definitely want my own lug wrench. I like to keep a dedicated impact socket/breaker bar setup in the car and probably would like that better than the stock (if it had one) lug wrench anyways. I"m sure I'll buy a donut spare to strap in the car for trips where I still have trunk space. I plan to ceramic coat the wheels soon so they'll be coming off, hopefully. I was able to remove one of my center caps by hand with the included center cap wrench (I have the black forged cross spoke wheels). Is that correct tightness? Didn't see anything about that so far in the manual.

 

The oil change is important that the factory instructions be followed or about one quart of old oil will be left in the system and that will make a fresh oil change look like it wasn't changed; and, in fact, all of it wasn't. Sometimes even MB dealers get this wrong, either be ignorance or on purpose.

Take a look at this thread, post #31. Make sure your dealer is following this procedure, to the letter.

Hi,

25Nm approx. 18.5 ft/lbs
Its normally cast into the cap wrench

Kind regards

Stenzel

 

That's funny, i think i remember seeing the 18.5 ft/lbs label and not thought just figured that was related to the lugs and then saw your 130 lug nut recommendations and just figured I had misremembered. Btw, I still got the overfill warning now with 2 full quarts removed. And my oil is definitely dirty looking. I bet that non Mercedes dealer never offers to change an AMG again, especially after I complain about this.

 

I'm at 3 quarts removed now. We'll see if that's enough removed next time I get it up to operating temp.

Ran into a couple more issues. I can't adjust the balance or bass on my stereo is that normal and related to not having the top end option? My passenger side rear view mirror is maxed out but still barely turned in enough for me, others have that issue?

 

As far as the mirror, someone might have pressed on the glass and moved it past the motor settings. I would just, lightly, press in on the inside (closest side to the car), part of the mirror glass and then see if the switch will get it even closer....

This should help you for the stereo adjustments.....

 

Thanks. I had not figured out that that clicker device clicks forwards and backwards. Guess I didn't read that far in the manual or find such an informative video yet.

Yes the passenger mirror issue seems weird but it's tolerable. It is already heavily angled. It's almost like Mercedes mounted the mirror container itself so straight that angling the inner mirror as fully as possible would be needed if the seat is very far forward at all (I'm 5'9). I'll be taking the car in for a service soon, kind of wanting to check for issues that I'll want to ask about before I take it there.

 

Had time to inspect my paint much closer. I'm shocked that this car basically had no road paint chips after 41k miles. Maybe it was wrapped but it would seem strange that it would have been removed already. I also guess someone could have touched up any nicks, etc.

What I did find were a couple of areas brown areas on the black outer coating on my aerodynamic package side skirts. Looks like the skirts are made of some sort of brown material with a black coating. Shouldn't be too hard to touch up, hopefully. Have others had this issue?
