Code P2004 question
I have been the happy owner of my 07 550 cabriolet since January. When driving the other day the dressed CEL came on. I pulled the code when I returned home with the car driving without any issues and the P2004 code with the description of stuck variable intake control bank 1. I immediately went to this forum and other internet sources and read about the reason for the code. When I went to the car to see the expected broken lever I was surprised to find everything in working order. The lever from the activator and both arms are connected and work in synchrony. Can anyone shed some light on other possible reasons for the code? Also ,is there any reason to not continue to drive the car since it seems to run fine?

I decided to check the code again and found a code p0025 in addition to the p2004 . My question is what conditions would cause both the codes appearing at the same time with no drivability issues? I am confident that within the vast knowledge of the members of this forum someone can help me out with a plausible answer for these codes.

NO LONGER ACTIVE
Those are two separate issues, but both somewhat common problems with this engine. P2004 is a bad tumble in the intake manifold. The proper fix is to replace the entire manifold. Sometimes, there are other ways to fix this this, by replacing a broken external actuator arm with an aftermarket metal piece, but if it's internal, you don't want broken parts sucked into the engine.
P0024 is a bad camshaft adjuster solenoid (a.k.a. "cam magnet"). There was a TSB for this on your engine. Need to replace all four camshaft adjuster solenoids. Parts are about $100 and it's not a difficult DIY if you are so inclined. Otherwise, I'd expect to pay less than $400 at good indy shop.

Thanks Rodney for your response. My confusion over these codes is that the linkage for the variable intake is not broken. I inspected it thoroughly and it is intact. Somewhere in my searching on the internet I came across a posting that said the 2 codes were related and that the problem was the cam sensors and it triggered the p2004 code. It seems unlikely that both problems happened at the same instant, so I am inclined to focus on the cam sensors. If anyone else has come across both codes at the same time ,I would appreciate some input.

I Read something about that and put a charger on it yesterday. The charger indicated a low battery. Since the car has been sitting for the winter it may be the battery.

So as I posted ,I put my trickle charger on the car for 24 hours after reading that a bad battery can cause unrelated codes. I took the car for a ride yesterday and after the third start/stop cycles the CEL went out! Thanks to everyone for the helpful input. If more codes come back I will replace the battery.

Hey I know I’m late to the party but I have the same issue with my S550! First I got a p0025, went ahead and replaced the cam magnet, and sure enough I then get a p2004. Same as you, no broken actuator. So this could all be from a bad battery?? And which battery was it in your case? Because my engine bay battery is up to voltage but I know for a fact my trunk battery needs replacing. I would very much appreciate a response as this has been a giant headache, I fix one problem and boom! Another one appears. Thanks.

Got it, didn’t even think about that. Thanks. Do you have any idea if in my case the battery could be the culprit? Same exact codes as ptrigg. No drivability issues. And on top of that sometimes while I drive a red battery icon will appear on the dash. I know my trunk battery is larger and is the battery that controls the electronics of the vehicle, while the engine battery is strictly for starting. So with that said if that battery was low, which I know it is, that’d most likely be the one to trip false CEL codes. You said this is a common thing?

Common mistake
first the battery in the trunk is for starting the car. the battery under the hood is for accessories. Yes low voltage can cause false issue all over the place. Yours being an 07 s class has sbc braking (brake by wire) there was a class action against MB on at very least the w211 e class (i own one) that extended the warranty. I would have it checked out as there is something like 300k pushes before the computer just says it is bad.
