AMG63 R&D #1 (Free 18 RWHP)

Anyone with the Engine Light? I just did my C63 - removed charcoal filter, but I've added also K&N. After about 20 KM - engine light. I am going to put stock back on without charcoal. Will engine light go away in a bit? ( Damn, I miss my VAG-COM cable)

no lights ever here from that. Did you damage one of the sensors on the sirboxes when swithcing them out? DIsconnect battery to hard clear light and drive again. If engine light comes back you will probably have to get it scanned to see what the code is. i have never heard of ANYONE getting a check engine light from that, and probably 90% of these forums have done what you did.

I've tried your solution, disconnected battery and plugged it back in 15 min or so. CEL right from the start. Drove a little bit but it didn't go away.
Returned all to stock and going to a dealer tomorrow.
Another thing - i've installed LED's in my lids just about 2 days ago. They are also known for throwing a CEL sometimes.
Really wonder what diagnostics will show tomorrow.
I didn't touched the MAF. I've been doing filter swap for a while now to make this simple error, but who knows.
I am guilty of breaking a rule - never install different updates all at the same time (unless you have a diagnostic tool that is

No CEL ever from what? Charcoal removal? Probably and most likely you are correct. My mistake that I've installed K&N at the same time and as far as I know K&N can cause CEL. However, it never happened to any of my VW's or Audi's.

Thanks for you response. I might be a bloody gas gap as well, just a coincidence. But I am not alone with K&N and Charocal = CEL. Here:

Indeed. BTW, I am coming from VW/Audi camp to Merc and I am really missed my VAG-COM software and a cable. Is there anything remotely similar to it at least in terms of diagnostics and simple code delete like this case?
#87
I dont know really. Fortunatly enough people I seem to know around here have a few STAR diags around to help out in these situations. Sorry maybe someone else can give you a better idea.

CEL UPDATE
Well, I went to the dealer this morning.
I don't remember exact code, but it was something "running lean" in both sides. There were no codes about LED's.
SO. I now can officially confirm that my CEL was caused by combination of removing charcoal filter and installing K&N at the same time.
I am not going to try and remove charcoal alone until I receive my ODB 2 diagnostic tool.

It too bad cause with the K&N's and no charcoal filters does give some extra nice power.

kinda weird that only a few cars get affected like that. Cause myself and the majority of people have done this exact thing without issues. Go figure. Sorry to hear you are one of the minority that has had trouble doing this.

UPDATE
Just removed charcoal filter at this time and left stock ones. So far - no CEL. I'll wait for my ODB2 tool and will try K&N again.

another tip . follow the air intakes right in front of the hood in front of the grill and unsnap plastic clips and fold back . Intakes are almost 70% blocked off from these plates .

Well Ladies and Gentlemen, the time has come to unlock the secrets of this new, wondefull engine.
To establish the baseline, I used trezai's CLS63.
At 1000 miles he dynoed his car at another shop and, if I am not mistaken, ended up with 414RWHP on Dynojet 248.
After 3500 miles the car put down 424RWHP which is exactly what I was expecting it to do. Unfortunately, due to the lack of time, we could not find a way to pick-up rpms, so there are no TQ readings - only wheel HP.
While the car was cooling down, I took the airboxes off to examine them. The box size is a bit on a small side. Bigger design would be worth some power. More importantly I found an easy 18RWHP in them.
When you take them apart, besides stock air filter, there is another kind of filter - Charcoal (Please see first picture) - it's function is to keep vapor emissions from escaping through intake manifold and air boxes.
On E60 M5, which has the same filters, removing them was worth 12-17RWHP. So, out they go. Using a flat screw driver simply push the edge of the filter out from behind the tab and 10 seconds later it is out.
On the dyno, car went from 424 to 442RWHP an 18 HP gain, with a nice bump accross the whole curve.
So get your tools and get at it -
Thank you for listening.

Have your dealer check and see if your 63 is under recall for intake manifold vacuum leak. Some cars needed new gaskets. That could explain the lean codes.
Good Luck!

Thanks for the advise, I will check. But in this case lean codes will be there even with all stock, or you think that removal of charcoal just aggravates the situation?
