Hello Guys,


I removed my charcoal filters today, i unplugged the two sensors that are connected to the airbox, took out filter and refitted. I then reassembled everything , made sure everything was connected properly. It feels like it has more oopmh! anyway to the point, car drives fine and everything, but a hour later a got a Check Engine Light, could this be related to me taking the charcoal filters out or a whole other matter? car just got back from dealership with a service D.

 

Not to be rude or anything but if you pulled out the charcoal filters then you got a cel- it's pretty obvious that the removal of the charcoal filters is causing the cel. Reset the cel and see if it comes back on, if it does- put the filtes back in and reset it again and see if it comes back on. Do you have a code reader?

 

my charcoal filters are removed and i never got a CEL.

 

Many guys here have removed the filters, I've never read that anyone had a CEL becuse of it Take a look under the cover with the star for a loose vacume line.

 

my friend removed charcoal filter from C63 but didn't notice any gain...

 

i will check again for anything loose. Thanks guys. can you reset CEL by disconnecting the battery?

 

Actually, quite a few E63 guys got the CEL early on. I do not remember the "fix" but they did not have to put the filters back.

I'd like to see data on improved performance.

 

I have a service appointment on the 30th, they are giving me new wheels to replace the current ones as they are starting to flake. Anyway so should i try to find the fix on these forums, or tell the dealer my CEL came on? also if i take it in should i put the filters back on ?

 

No CEL here. Filters were off since day 1.

 

hmm... maybe i disturbed one of the connections to the MAF sensor... car runs great though.

 

If you turned the key to the on #2 with the Mafs unpluged it will CEL..

 

the CEL came on about 1hour to 2 hours after i removed Filters

 

I would recommend putting the filters back in then just telling the dealership that the cel's came on after you picked the car up from their servicing it.

 

Go to Kragan and buy a code reader for $49 it's very east to use and lets you reset the CEL.. well worth it for a MOD HEAD

 

Ok, i will pick one up and i will let you guys know what i find out, where does the scanner plug in?

 

Does air flow matter?


I agree with this poster. Put them back in and take it in.

 

will do guys, thanks for your advice guys. That way i can see if the code is related to what i did.

 

It is a standard On Board Display II (OBDII) hookup and it is just up under the dash by your left knee. There should be a little red flip door to access it and the cable simply snaps in. Very simple.

 

i am going to try this tomorrow, but i will end up refitting everything and sending to dealer.

 

On-Board Diagnostics

NOT On Board Display

once again slinging the terms without understanding them...

 

What a turd! Lets let the OP say who has been more helpful, ok? You with your perfectly mechanic head or me with my enthusiast know nothing? Attitude is everything when it comes to contributing. You offer jack!!

 

I offer correct answers, you just offer noise, lots of noise

 

I appreciate all the help guys... i am truly glad i am a member of the forum, by any chance Jangy do you where i could find the fix you mentioned earlier?

 

Is that PartsAmerica? (http://www.partsamerica.com/CodeReaders.aspx#) If so the all OBD-II code readers go for over $120. Could you give more info on yours?

 

And what question have you answered?
