pinging under heavy accel
so i have been noticing that when i punch it the initial burst will cause my engine to ping...i am using 94 octane so that should eliminate poor fuel, the car is completely stock there should be no reason for it to ping!!!

Unfortunately these engines are notorious for pinging. I took my ML63 to dealer and they "played around with timing" and fixed it. I occasionally get pinging in all my AMGs but very intermittent.

Almost certainly fuel/timing related if it is pinging.

I'm envious. I've had two C63's and both pinged pretty regularly on 91 octane. The inside of the gas door says minimum 93. With higher octane the car runs much better and no pinging. I've heard of other 63's that don't ping on 91 octane so I don't know what the story is with my cars. Anyway, the ECU will protect the motor in quick fashion when it senses knock.

I have no clue how your engine is pinging off 91 octane... There are knock sensors on the engine that will retard the timing if it senses knock (pinging)... I believe the engine has the ability to protect itself a fair amount.
Realistically, you could put 87oct in these engines and they would just retard the timing to adapt to the fuel.
I believe its something else.

I find that hard to believe. Perhaps they have a faulty knock sensor than.
Maybe Weistec can tune in on the M156's ability to retard timing and protect itself.

I always use 94 octane..I to take the car in next week and have them take a look at it....there is no way that an engine with 40k using 94octane should ever ping

The fuel, how can you be really be sure what you used is what what advertised at the pump?
Or if the fuel was stale or had some water in it?
Try another source for fuel and check again.

I am quite sure I've never heard the noise when manually controlling the gears...only when it's left in auto and has to slam down several gears. Maybe that's a test you could do to get more concrete data, if you haven't already. Have the car in M and floor it at various RPMs in various gears.

Lets say it pings and its more of a headache to look into it and all your guesswork wont fix it. Pinging won't do anything unless its valve related or cam related so I am thinking the engine will run fine, you just have to block out the noise...

you have it wrong buddy...pinging will do a lot of damage to your engine, normally an engine that is pinging because of timing or fuel issues....if your are not getting enough fuel to the engine you will run too lean meaning your engine will be running at mad temperatures and you will find your self with a massive empty engine bay when it explodes lol...

[QUOTE=ZephyrAMG;5300484Second you will have over heating first and foremost so coolant and temps would alerting you way ahead of time...[/QUOTE]
coolant temp and internal combustion temp are totally different....your vehicle will be running at normal operating temp and your combustion chamber will be melting

I believe it is nearly impossible for a stock car to ping. You have something called a knock sensor which will retard timing, even if you put 87 octane in it, I doubt you could get it to ping.
Dont you think the merc engineers thought that someone might get trapped on the highway or something where 91 oct wasn't available?? I doubt they said, ahhh screw it if they cant find 91, lets just let the engine detonate itself apart.

You should try 87 octane and see how it works out. Report back.
