Hi Ali,
I think I am experiencing the same problem as you.
I have a '12 CLS63 with a Weistec Engineering Tune on it.
at about 2 weeks ago (the car had 3800 miles), my spark plug broke when I was accelerating the car at high speeds (above 100). I took it to the nearest service center (Arcadia SoCal) and they said that it was from cylinder 1, so they changed all of the spark plugs.
2 days after I got my car back, I punched the car again to high speeds, and when I was accelerating, suddenly the car vibrates really hard and the engine light came on (but there was no misfiring). However, the car was actually driveable (with the engine light on) but at only speed below 80 mph. So, I took it to the dealer again, and they couldn't really find the problem. They reseted my ECU and the CEL was gone. Until yesterday, it happened again, when I was accelerating the car. The same **** actually happened all over again. Accelerating above 100, CEL came on, and sudden heavy vibration from the engine everytime I step on the gas.
Anybody has any input to my case and what should I do?

@otherbenz: on the third times, did you actually still have the tune or stock setting on the car?
@dbasson: when i turn my engine, i actually feel unusual vibration, is it better to change the spark plug for safety issue? what spark plug you recommend for this car?

When I had my spark plugs changed, they actually reseted my ECU to the factory setting and I have not retune the car since then. So, all these happened when my car was at stock ECU

Other problems that these new M157 engines have as declared by dealer:
- first year spark production have quality issues.
- all pistons vibrate a bit and there is a new pistons update with diffrent connecting rod that have coating which doesn't make the rod a bit oval shape and the piston doesn't shake ( i saw it by my own eyes )
- fuel issue from the front pump which makes the car starve for fuel @ high speed or WOTs ( maybe this is your case ).
other than that there have been 2 recalls :
1 - passenger side airbag doesn't open to stage 2 in case of strong accidents
2- steering mechanical failure that make the steering wheel havier but drivable.
depends on your VIN.
there are alot Aftermarket Spark plugs i found that fits and manage higher powers + insane boost and colder, step 8 and 9. our stock is step 7 colder.

I don't really get what do you mean by the fuel from the front pump. So, basically my fuel pump is faulty?
and what is WOT stand for?

your front fuel pump could be fualty or weak.
WOT = Wide Open Throttle, AKA Kick down or Full acceleration

in our cars there are 2 fuel pumps @ the back with 65PSI and 1 in the front on passnger side 200PSI ( which makes the ticking sound under the hood ), because it is a direct injection engine
your front fuel pump could be fualty or weak.
WOT = Wide Open Throttle, AKA Kick down or Full acceleration

What is your suggestion for my next step?
should talk to my SA about this?

if your plugs are all fine, maybe there was a damage that happened when one of them broke the first time, exhuast valve is open, or injector if not functioning right.
let the dealer check fuel pressure while driving it or check the values @ idle.
it could be one of your blow vlaves, these engines are sensitve, any small failure will make it PITA, my car was drivable when my exhuase valve was broken after i changed the plug, but there is a vibration.
so it depends on how the plug broke ! did something fell inside the engine ?
better to let them do a compression and leak down test if something fell inside.

if they don't know what to do like our SAs LOL to that, yes yo can.
or tell them in a seruios way, if it is not fixed you will return it to them and ask for you money. or replacement.

@ali: when i start my car, the steering wheel seems unusual heavier like 15-20% than before but this is happen only sometimes, for the new piston rod, is it require to change that? because i dont think dealer want to change that if there is no serious issue to the engine
and for this one "passenger side airbag doesn't open to stage 2 in case of strong accidents" how do you know if it is a failure or not? because last time my car giving me notice that my passenger airbags is not functioning... and i dont know if this is only in my mind or for real but, when i do kickdown or highspeed travelling, my gas seem so ineffecient at all

About 6 months ago it was posted that there was a VIN specific recall on plugs. I called my SA and he checked and he said mine were fine. TWO HOURS LATER my car starts to hard idle and a cylinder shuts down. Rolled into the dealer on limp mode. It was the plugs and they changed them out under warrantee. We pulled those plug yesterday and after 7000 miles of hard use with a tune including 100+ degree track days the plugs looked perfect.
The guy who works on my car thinks that the power of these new tunes may be blowing out the spark randomly across the cylinders causing misfires. We were advised to go one step colder and we did...also closed the gap up and we are no longer getting codes and its on the track today being tested. So far so good.

Reason I ask is that I will be getting the Renntech tune in the coming weeks and plan to run the stock plugs. I want to be sure I will have no issues doing this.

So on the new dealer plugs, were you getting codes and CELs on the Renntech tune? You mention the plugs were perfect after lots of hard driving, but did you have any drivability issues during that time?

We added downpipes, Renntech's intercooler upgrade, race filters and a ice box intercooler system which is making a huge power difference...air intake temp as low as 60F. It was only after we did all this, and retuned for it, that we changed the plugs. Got the same codes before and after. And they're BMW plugs...like getting a transfusion from the enemy...lol.

Other - This isn't any kind of silver bullet for you but a specific recommendation made to me with my set up. If I were you I'd be working with my tuner for a solution.

The dealer just called me and said that it was a CEL misfire code, but the misfire only happened once. I told them to run the compression and leak tests but they said that it won't be necessary because there are no codes telling them to run the tests. What do you think?
Thanks!

I have no idea man. Could just be bad gas too....who knows...so many variables but the gas out here sux big time. I guess you have to trust your dealer though...

if there was no parts fell inside the engine, than no need to do leak test.
piston and rods update is not required under dealer cost.
they will start giving you truoble after 100k km. and they will slowly scratch and widen the engines bore due of vibration.
nice to know freefall you changed your plugs to colder ones.
how much HP are you making now with your last mods ?

My car ran perfectly with the Renntech tune for about 7000 miles on stock plugs...and like I said when we pulled them out they look at plugs should look...text book. Great increase in power and zero issues. Plug and play brother.

Hi everyone,
Just an update on my car.
So they did the fuel test and it was fine.
I requested them to do the leak down test and the compression test but they refused to do so because there are no CEL Codes telling them to do so.
This morning I got a call from my SA asking me what mods I have done to my car performance wise. I said I only mod the exhaust (resonator delete).
He told me the CEL came on because of the straight pipes because there are no back pressure. Is it true that straight pipes can cause this? or the dealer is just looking where my mistake is?
Thanks
