I have summarized all of the service procedures requiring parts replacement from the Mercedes factory Service booklet specific to the AMG GT and GT-S. I did not include all the inspections of parts and systems indicated for service A & B.
There have been multiple service intervals given here for the 190 series car, but these are from the factory documentation which was current for my 2016 GT-S.
MB made some changes to the service schedule worldwide in 2019.
It is not much different than the earlier version, but for us, the main change is in the transaxle service schedule, which was changed from every 40,000 miles to every 30,000 miles.
If one does not drive a lot, you can convert every 10,000 miles or 16,000 km to one year. So, in the example of the transaxle service, it should be done every 30,000 miles or $3 years, whichever occurs first.
See post# 269 above for current schedule and a downloadable PDF
Yes, it's applied to ALL models (with some changes to the G, SLS and SLR models).
Here’s the logic:
Almost all MB/AMG models are built on very similar platforms, so their service intervals are largely the same, with only a few exceptions.
The core idea is that the dealer sees the car every 10K miles or 1 year, hooks it up to the Xentry diagnostic system, and performs both electronic and visual multi-point inspections.
If anything is out of spec that isn’t part of the standard service interval, they’ll flag it for you. Otherwise, there’s nothing to do beyond the regular interval maintenance outlined in the service brochure.
One additional recommendation I’ve heard consistently from multiple service techs is this: if you track the car, add an extra oil and filter change between the 10K-mile service intervals — essentially, change it every 5K miles. Brake fluid can also be accelerated based on your track usage. (You can also ask for a multi-point inspection at the 5K mark, just to be safe, if that gives you more peace of mind )
The GT platform is solid, don't overthink the maintenance.
As for the rear-wheel steering mechanism, I imagine that, in the absence of malfunctions, no maintenance is required. Is that correct?
(Please forgive me for asking all these questions, but since I may purchase a GTC/GTR in the future, I need to know all the pros and cons of this stunning car!)

Correct. It’s essentially a maintenance-free system. During your 10K/1-year service, the dealer’s workshop inspection manual, specifically under the rear-axle inspection section, will reveal any potential issues, if there are any.
Service A and B, alternates every 10K miles. Transaxle fluid service happens every 30K miles. See tables below:
This is for ALL AMG Models (Blue dot is for MY 2009-2014)
For our AMG models Transaxle fluid change and Engine air filter - Every 30K Miles
For regular AMG models, not the GT's, there has been a requirement for early change of the rear axle oil change as shown in your table. I do not see how this applies to AMG GT's that have a transaxle by Getrag.

I don't have much info for ROW, but in the USA, it include the GT's.
Open the PDF attached to post # 269 above, or check with your local dealer.
Even on Ferrari (USA), which originally designated this Getrag 7DCL750 Transaxle as " filled for life" , changed it to 30K Miles.

experts opinion needed... I'm in the process of negotiating the purchase of a GTR registered in February 2022 with 3,400 miles on the odometer. Assuming for a moment that the maintenance schedule is the same for both the North American and ROW markets, could someone tell me specifically what maintenance should have been performed on it so far? The dealer showed me the maintenance history to date, and I see a Service A in 2023, a Service B in 2024, a Service A in 2025, and a Service B this year, but what was done during each service isn’t specified... thanks
P.S. I still don't understand why a thread as important as this one has to be searched for among all the others every time, instead of being pinned... Could the moderator of this section kindly take it upon themselves to move it?

I have a 6.5 year old GTC that I bought new and now has about 7000 miles. The only important maintenance items are annual oil changes and brake flushes every 2 years — or more often if tracked. Everything else is a waste of money.
You may want to do the diff and trans fluid at 4 years; but I’m just doing mine now.
thanks for replying, I was asking because the car is (must be) sold by the dealer in accordance with the maintenance schedule set by the manufacturer up until the day it is delivered to me, so I expect even the “unnecessary” work to be done—since it’s at the dealer’s expense—even if it’s just a measly cabin filter...

Ha your comment made me laugh because the cabin filter is by far the most difficult maintenance job to do on a gt. The reason it’s so hard is there tiny metal clips as well as screws to get the cover off and it’s in the passenger footwell which is tiny and you end up with your back on the raised door sill. VERY Difficult.
AS a matter of fact I would rather replace fuel injectors or spark plugs (which I have done) than replace that dam filter. Would be easier if passenger seat was removed but I did not do that.
Ps throw in brake fluid changes, trans fluid changes, and exhaust actuator valve replacement. All easier than replacing that filter.

Agreed, was about to say the same thing!
I'll do mine at 20,000 km - I don't see much point in doing it sooner as it doesn't degrade over time.

Where do you get that from? If a dealer is selling a pre-owned car, the best they can offer is some kind of "certified" warranty, which probably doesn't carry much weight. The only thing I would rely on is an inspection from a mechanic you trust and/or a friend who knows the car well.
Yeah, you're right, I picked the worst possible example (I had read the discussion on that topic), but my point still stands: if there's even a single bolt that Mercedes specifies should have been replaced between when the car left the factory and the day I bought it, I expect it to be replaced! (In the purchase contract, I specified that the car must be up to date with the manufacturer's recommended maintenance schedule.)

@Katie22 doesn’t the exhaust actuator valve require a new exhaust pipe, or cutting into the pipe (which dealers won’t do)?
@Kevin#34 just my 2-cents: you are better off getting the car professionally inspected by an AMG mechanic whom you trust, then relying on this “if there’s even a signal bolt that MB specifies… I expect it to be replaced!”. I get where you are coming from, but this will be nearly impossible to prove if something goes wrong. The fact is that it’s pre-owned and out of warranty, so anything can happen.
I don’t want to discourage you - they are great cars and very reliable.
The car was registered in April 2022 and comes with the std. 2-year Mercedes wty + an extra 3-year warranty option, but it is valid only and exclusively if maintenance has been performed according to the manufacturer’s schedule and specifications; therefore, the dealer must verify that these conditions are met, otherwise, they cannot sell a car claiming it is under official warranty when in fact it is not (because, for example, a service may not have been performed on time or as required).

The car was registered in April 2022 and comes with a 2+3-year official Mercedes warranty (maybe not existing in US?), but the warranty is valid only and exclusively if maintenance has been performed according to the manufacturer’s schedule and specifications; therefore, the dealer must verify that these conditions are met, otherwise, they cannot sell a car claiming it is under official warranty when in fact it is not (because, for example, a service may not have been performed on time or as required).
That’s not really true - the warranty is not voided if service was not performed — although that is a common misconception. It certainly helps if it was performed though. But that’s easy to confirm - all work done on the car (assuming it was done at a Mercedes dealer) is stored with the car’s VIN. Any dealer can pull up the service history. This is your best way to determine if the service was done.
Maybe it’s different where you are, but here in Europe, if maintenance isn’t performed as scheduled, the warranty is void, and the maintenance history only shows the various Service A and Service B entries along with the date they were performed and the mileage, but no details on what was actually done—otherwise I wouldn’t have asked here...

Service A and B both only require an oil and filter change, with the addition of the cabin filter change at service B. There is no other detail to provide, as all that is done are simple checks with nothing needing replacing, and certainly no bolts need replacing.
ok, engine oil and oil filter changes at every year and -as said by somebody else, at least 2 brake fluid change... that's all in 5 years?
PS: the " a single bolt to be replaced" was obviusly just a way of saying...

Maybe you should have posted the image of the history first? I certainly missed that whole "Rome" thing and I am sure others have read posts without checking that bit of your profile.
I am not familiar how MB in IT works but I know MB DE and MB FR has a RO similar to what most US based dealerships provide. You need to ping SAGA and CENTRUM individually to ask them to provide the actual RO. I do think there has to be a digit after service A or B. With that digit, you can decipher which services are supposed to be completed.

You’re right, I didn’t mention that I live in Italy, but I did say Assuming for a moment that the maintenance schedule is the same for both the North American and ROW markets in my original post. In any case, the car in question is from the German market and, as you can see from the photos I’ve attached, the service reports only list the type of service carried out (A or B), the date of the service, the current mileage and the name of the service centre. There must surely be a way to obtain a service report that specifies exactly what was done, and I will raise the matter directly with the seller because I don’t want to continue cluttering up this interesting discussion explaining how to carry out certain jobs on your own car. Thanks anyway to everyone for their contributions.

This is the US-specific service sheet but it shows everything covered in Service A and B.
Thanks for posting that. The factory 2019 WIS service document AP00.20-P-1240GP for the 190 series GT shows transmission fluid change every 40,000 miles (60,000 kms), which is the same as in the file I posted previously.
