c63 chugging violently
My car started chugging today with no CEL. if anyone has any tech input it would be appreciated. Here is what I told the dealer.
Outside temps are getting cold
Oil temp was 71 F (22 C) upon cold start and car Chugged HARD when accelerating
Oil temp was hot and still had mild chugs accelerating under freeway speeds
I just did A service last week, oil was changed 0w-40 mobil 1
I put BMC filters in a week a go.
Use Petro Canada Ultra 94 gas.
Dropped the car at the dealer today they look at it tomorrow.
Update:
Dealer told me they found no codes or errors via testing but knew something was wrong after they drove it and it started chugging. I mentioned about the upstream O2 sensors, MAF, and my air filters. They still couldnt find the cause, the data they pulled was sent to Mercedes techs to see if they can figure it out.

CAM sensor OR MAF.
if you JUST installed new filters and any residue contaminated the MAF that would/could screw with the A/F compensation from the ECU.
or bad gas? its never bad gas but it would be great if it was!

.5 + bad gas
..I always blow out new filters with air when i just get them. Most people add to much oil WHEN THEY recharge them. Not really when they just bought. make sure your MAF's a re plugged in tightly and clamps closed.

I hope you removed your BMC filters before bringing it to the dealership? They might not honor the warranty work due to the aftermarket filter. (if the problem is caused by it)

Go to the hardware store and buy three bottles/ cans of Touline and pour it into your tank. I bet you $50 problem solved 
ps if you rank is full 3 cans if it's half 1-2 cans

,get someone independant that knows how to use a logger and log o2 activity when it chugs & you will know right way which o2 sensor it is.regards sonny

My dealership took 2 times before they found out which 02 sensors was defective... it was starting to make me worry. I'm glad they resolved my issue, hope you will have better chance today blackbenzo!

Thats ridicolous,its easy to log upstream o2 activity and easy to tell if they are functioning correctly,if they cant do that as a merc dealership,they might as well shut shop ,get someone independant that knows how to use a logger and log o2 activity when it chugs & you will know right way which o2 sensor it is.

- Jack the vehicle up and remove the lower plastic tray.
- Under the transmission bellhousing you will see the o2 sensors plugs.
- Follow the upstream sensors to the connector and unplug them both.
- Then take the car for the drive to see if the issue is still there.
- If the issue is gone,then you have faulty o2 sensors,if its still there,then its not the o2sensors,Just a note,you will get a check engine light,but dont panic,its becuase the o2 sensors are unplugged,let us know how you go

I'm glad the chugging is gone. I don't think it's a bad cam sensor 'cuz you would get a CEL & the car would probably be on limp mode. Maybe you fixed your problem. So you're leaving your car at the dealer until Monday?

I agree with you blackbenzo, after the warranty expires I'm taking my car to Young's garage on Preston... I heard great reviews about them on the net. I also talk to the owner, he is very knowledgeable about AMG cars... their price is at least 25% cheaper too. They specialized in Benz & Volvo.
