All you guys with coil pack issues have been misled!
I started my CL65 up last week and it felt like it was running on 6 cylinders and the CEL came on. Knowing the V12TT was plagued with coil pack issue I had it towed to the dealer rather than dumping fuel through the engine. Upon inspection they noticed the gas gauge had just hit the low fuel warning light and somehow they calculated that there was only 4 quarts of fuel. They added $40.00 in fuel and Voila it ran like a champ. When I asked them how low fuel would discriminate between one bank of cylinders and not the other the tech said he doesn't know. I said that's because it cant, its the coil pack. He said the problem was fixed and they would not replace my coil pack. They also couldn't fix a whining noise coming from either the power steering or ABC pump. Their recommendation was to drive it.
Drive it I did. On a business trip to Chi town I started my car and guess what? Well I drove straight to the closest gas station and added 3 gallons of gas to an almost full tank and I'll be a monkeys uncle if the engine didn't start running better.
All you buys had to do was stop and add a little more gas to the tanks.

Car was connected to computer, car was diagnosed, coil packs need replacement, packs were replaced, problem solved.
By your experience with the stealer, they will not replace them if not needed.

Im pretty sure by "hook it up to the computer" all they do is pull the codes. Based on the codes they are probably given a logic flow table of common problems which can cause these codes. Obviously my dealer chose to beleive that the low fuel could somehow cause the entire bank of cylinders to misfire.

Perhaps you can explain it to me.

Obviusly you missed my satire. The problem was resolved when the engine warmed up.
If you read my post you can see that the condition was exhibited a few days later with nearly a full tank of gas. How could anyone who undertands how a fuel system works possibly believe that low fuel was the problem to begin with?

The car did not get fixed, the problem is still there it is just intermittent. I remember reading a few other guys noticed this as the coil packs were dying. I honestly believe it is just a matter of time before the coil pack dies all together.

Yeah....I got that. I actually was verifying your argument......albeit in my own way, based on my experiences.
I had the left bank replaced 2 years ago with: A275 150 07 80 Q3
I had the right bank replaced 2 months ago with: A275 150 06 80 Q4
Hope this helps.

XABO, don't waste your breathe.....your are a stand up guy, a gentlemen kindly entertaining someone who still thinks the earth is flat... The older coils have been proven to fail otherwise why were they updated??? Many situations occured with some not all or one misfire scenarios. There are other things that cause misfires, and to come here and state with a great deal of certainty that low fuel levels are the cause is just crazy.

No offense to you friend but that was your issue with the car, not everyone else's. We have not been misled in any way. The coils on these cars do go out, just because you run a low fuel level does not mean that the issue is with fuel.

Which is exactly why I gave the dealer that look. I made it clear that low fuel would not cause misfire codes in just one bank of cylinders. My original post was poking fun at the dealer, no one else. I thought everyone would catch on that the problem went away because the engine warmed up, obviously i was amiss.

WOW so all this time V12 guys were changing coils pack and spending thousands of $$$ for no reason when all they had to do is put a few gallons of gas in their tanks....... damn Mercedes and Dealerships for "Stealing" money from your poor V12 customers how dare you....
