21 G63 CEL Already...
Hello everyone,
I'm new here to the MBWorld, and this isn't exactly the first post I wanted to make about my new purchase. Just about a week ago I was fortunate enough to find my dream spec G63. A brand new car that was not even test driven yet. Just about a few days later with about 100 miles on the dash I get a check engine light. I took the car to the dealer and was told there was an engine misfire in cylinder 2 and 6. This is definitely not the best introduction to the world of AMG. I'm hoping this issue is going to be addressed, but it's a bit concerning that something like this can come about with just 100 miles. I am curious to know if anyone here has experienced something similar. Or if anyone has heard of similar stories. Any help would be greatly appreciated.
Thanks

Such experiences are the best reason to buy an OBD code reader. Even a loose gas cap will set off the CEL, and you don't want to spend time and $$ at the dealer to remedy such trivia. Cylinder misfires could be more serious, but knowing the code(s) you can ask if driving the vehicle is safe or if it needs flat-bedding.

I know here in Canada there is a recall that affects a small number of GLC43s and G Wagens involving ignition coils. Misfiring on multiple cylinders is one of the issues identified. Parts are not yet available.

You will need to be a bit patient - in your situation the "AMG Tech" at the dealership will do the Tests requested in Star - which get uploaded to MB for their Tech Review - then "usually" MBUSA tech will request additional Tests - those then get done next - those get uploaded - and sometime over the next 2-3 days of that - then MBUSA will authorize the replacement parts/service that MBUSA believes will solve the issue.
Yes - there have been "some" coil/injector issues - not a lot - but some. Nowadays - the MBUSA "tech loop" is how MBUSA stays on top of potential issues.

Hi everyone, wanted to give a quick update on my car. Once again, I appreciate the replies. So I got the car back just a couple of days ago and was told by the AMG technician and service manager that they couldn't identify the source of the misfire. I believe they completed 8 major tests in total (minus the test drive because the car was not broken in yet). Since they couldn't find the source of the problem, the AMG tech just filled the car up with new gas. I was told to just drive the car around town and break it in to see if another misfire/CEL is reported (after about 100 more miles, so far nothing yet - thankfully). But I found out something interesting. Another G63 at this dealer (where I serviced my car) had the same exact problem 2 days after it was purchased. Another G at a different dealer had also the same issue. Not sure if this is coincidental or if there's clearly something wrong here.

Were these misfiring vehicles by any chance among those that were in VPC purgatory for 8 weeks earlier this year? Assuming they had only enough fuel in their tanks to survive the "RO-RO" expedition from Graz to the dealership, they could have experienced some fuel tank condensation while sitting around in an oscillating climate, and a bit of water in the fuel would induce a misfire. Buy a bottle of Heet and add it to your fuel tank. If it's water, Heet will help flush it through the fuel system. Or if your local fuel stations pump ethanol blends, this should accomplish the same after a tankful or two.
