2018 S63 AMG Issues

Dropped my car off at the indy shop and hopefully its something manageable for them to fix otherwise I will drop off at dealership.

This weekend , experienced when driving the car would shake like crazy when gasing and very rough starts. Alot of gas smells when starting up. So I decided to drop off the car this morning at the closeby indy shop for quick inspection and this is what came back. Now to see what can be fixed.

doesn't sound good, hopefully, it is a simple (inexpensive) fix.

Dealership gathered it could be the aftermarket exhaust (Capistro) causing it and will not warranty

3 spark plugs being replaced
2 ignition coils be replaced

After that will test it out some more..

Hmmmm, while I do not remember the name of the actual law, IIRC there is a Federal Law which might apply to the sue of (some) aftermarket items. Not to sure you want to get into a pissing contest with your dealer ( I only have 1 Mercedes dealer in my area, just an FYI)...... I would also check with Capristo..see what they say.......GL

Aftermarket exhaust will not cause coils or spark plugs to fail.

Period. End of story.

Coils die. Spark plugs die.

@Hedgey-
I just realized that you are in TO, so a US Fed law isn't going to help......... Did you get the issue resolved? If is the exhaust ( which I really doubt) does this mean that you can expect to deal with this on an ongoing basis? I hope not for your sake.

Been there done that with BMW dealership.... If the Plugs/Coils are not Mercedes original (even if they are OE aor OEM, they would make you change the plugs/coils first before going any further. For me lesson learnt was, if youwant to change your own plugs/coils, always use manufacturer original so if you do run into issue, they don't attribute it to the after market stuff

Exhaust shouldn't do the misfire and if they say yes it does, ask them if the mechanic can explain how it would?

As other have stated, misfires has nothing to do with aftermarket exhaust. If any issues you would have with aftermarket exhaust will come in the form of α check engine light related to O2 sensors or exhaust valves. In the US, if there is α questionable warranty work, the dealer will ask MBusa for approval, not sure how it works in Canada, but I imagine it’s the same? What did your dealer say OP after their diagnostic review? Best of luck it gets resolved quickly.

A quick update from previously

SA called me and explained they will warranty the parts and fixing it - they wanted to make sure I do NOT have any boost in the car before they download information off the computer which will void that warranty.
Finally it was warrantied and the following

1) replaced Ignition coil
2) replaced Spark plugs
3) Reman injector with nozzle
4) TS spring injector
5) TS oil filter
6) screw plug
7) Check Compressions

After all said and done it was replaced - they found out it was still having issues.

They suspect its the fuel injector and fuel kit and have that replaced which got the car running again. After getting the car back all was fine but few days after i noticed sometimes when starting the car the idle would be low and car would shake - than the RPM would jump up very high and back down again on random starts.

Yesterday when car is in Drive and stopped at the light or traffic for whatever reason - the car would just simply die. I'd put back to Park and restart the car which made it very dangerous to drive. When driving pass 60 the whole car would shake and rumble again.

Enough of it - sent back to dealership yesterday AGAIN so will see what the further analysis is.

Had a CLS63 AMG prior to this and it was giving me same problem after 4 years or so - i am starting to get my doubts with AMG's after several cars with the same issue. I am starting to get a sense of how unreliable AMG cars can be .

Car is fixed - replaced all fuel injectors and a hose that goes along with it now.

Lets hope this is the last of it!

Got my car today and so far it runs fine!

I am sorry to hear this........I can't imagine the frustration you are experiencing. Does CA have lemon laws..........Mercedes Benz buyback, as this issue continues to plague your car and the dealer has not been able to fix it?

I drove for alittle while more as it seemed to be one time only - than out of no where pressing the gas it started rumbling i park to side . Turned off car and turned it back on - heavy gas smell - saw alot of smoke coming out of the exhaust side . Enough is enough i called tow truck services to tow truck back to dealership.

Lets see how this one goes... I may get rid of this car now and perhaps get a newer 2020 S63 or so instead or try out Porsche Panamera / Taycan Turbo etc.

This issue has been going on for waaay too long. I use highest grade fuel available at gas station if its 93 or 94 octane or sometimes 91 if its highest but nothing lower than that.

I would keep “ALL” service invoices and if you don’t have them all, contact your SA and ask for copies of them. If Canada doesn’t have the lemon law like we have in the US, get a lawyer involved. I had issues with my SoCal purchased/driven 2017 W222 S63 and MBUSA would NOT accept my lemon buyback request, hired a lawyer who took my case and guarantee to win the case and if not, no bills for me. After all was said and done, other than insurance and gas, I received a check from MBusa for 93% of what I paid from the time I purchased the S63 to the time MBusa took it back and that includes the wheels and tires protection, extended warranty. Best of luck.

I was more so asking about the station. The AMG techs at my dealer recommended I stay away from certain stations. But it is ridiculous it keeps happening. Definitely may be time to get rid of the car or inquire about a lemon buyback.

That blows... I'd leave it at the dealer till the fixed the dang thing. I get so attached to cars, I just keep bringing it back to the dealer and trying their various loaner cars as it can sometimes happen when you have a recurring issue. They are very very complicated cars. I'd be pissed for sure though. The 2020 S63 is so much more expensive still... hopefully they can fix yours correctly this time.

This.

Hedges, sorry that you are dealing with these problems and how it keeps coming back especially on such an expensive car. We have something that is inferior to the lemon law in USA but it might still be useful in your case if all options were exhausted: https://www.camvap.ca/
Please tell your dealership to open a TIPS case immediately to escalate to MB Germany, you can also ask about it on the AMG Private Lounge and the forum admins might reply to you directly and escalate your issue for you directly. https://www.mercedes-amg.com/en/get-to-know-us.html

For gas brands in the US, dealers does not recommend using Costco or Arco brands no matter how high the octagon you use ( 91 ) in California.
