Hello so today I got a check engine light. I put a cose reader and got the fallowing codes. If someone can help I really appreciate it. My car is a 2004 clk500.
P2014-000
P2019-000
P20D4.

Thanks in advance

irokdastar

does no one know what it can be ?

Google is your friend, for example googling the first one gives P2014 OBD-II Trouble Code: Intake Manifold Runner Pos Sensor ...

irokdastar

I did google it but I can't find anything on a clk 500 . I am just trying to see what it can be .

irokdastar

Does the v8 have actuators like the v6 ? Thats whta I am getting from the searches or the sensor but I doubt both sides fail at the same time .

Rudeney

Here's the list of DTCs:

Thank you Rudeney , Very helpful . If you dont mind me asking you a questions . I had the radiator blow a few weeks back and I am guessing that is whats causing the 2019 code. the 2014 code is indicating a purge valve leak . The issue that I am having is sometimes when I go to step on the accelerator like when I am pulling into the highway . The car falls on its face and I get no power for a a second then it comes on . Sometimes I have to lift the off the pedal and hit it again to get power . Can this valve be the reason ? and should i Just get it replaced since its in contact with fuel ?

Rudeney

I don't see how a purge valve problem could cause that behavior. DTC 2019 specifically states that power output will be limited. Are you still having coolant issues?

irokdastar

No I fixed the coolant issue . I erased all the codes and only the P2014 came back . I unplugged one of the hoses yesterday from the purge valve and its working fine . When I read the code P2014 on my MBII scanner it says intake manifold runner sensor not purge valve . Any idea what the intake manifold runner sensor is referring to ?

Rudeney

As an MBZ DTC, P2104 is a purge valve fault. At a generic OBDII code, P2014 is an issue with the intake manifold runners. I thought that the iCarsoft tools returned MBZ DTCs, but maybe not? If it says its an intake runner issue, then yes, that can cause some performance issues.

irokdastar

when I pull the code on my MBII it says P2014-000 the fault code is not found in data base . When I search the code online it says its a intake runner control position sensor . Does this car have such sensor ?

Agent-A01

No.

Not be mean or anything but you've already gotten the list of correct codes.
Googling generic codes will not help you.

You shouldn't need to be spoon-fed the same answer over and over, all the info is in the web link above.

The purge valve is most likely your issue where the solenoid is stuck open/closed..
Replace it as it's a cheap part.

If that doesn't fix it then you have a leak in one of the hoses up/downstream towards the charcaol canister. Or it could be the charcoal canister needing to be replaced.

irokdastar

I am not asking to be spoon fed . If you read my comment I already checked the lines and purge valve and its working . And as Rudeney stated its not the cause for the issue I am having . So me throwing parts at a problem isn't really going to work .

Agent-A01

Spoon fed the same information. You asked the same question several times despite been giving the factory DTC codes

regardless, it is a fact that there is either a leak in the lines or the purge valve/charcoal canister have failed.

You need to look further into that.

A system without the proper list of DTC will not be very useful. It says it’s not in the database which means that it is not going to be very helpful in finding the correct fault.

I trust that the code is the correct one but icarsoft has no idea what it is. Generic codes for American cars are not applicable to Mercedes. If you don’t trust the icarsoft I suggest taking it to the dealer or an independent euro repair shop to pull the codes for you.
It shouldn’t cost much for them to do that but Mercedes will likely charge you for 1 hour of labor.

Rudeney

The issue is that iCarsoft doesn't have the right code in its database, so it just throws out the generic code. I suspect it is in fact an intake runner issue, which would be P2074 on the DTC list. It might be time to get it hooked up to SDS to verify. Note that the dealer is not the only option for SDS. Some indys have it, and many DIYers (like me) have it. If you are in a major city, you finn another MBWORLD member nearby that has it and would help with a scan. You should consider updating your forum user's profile to include your location, and also the model year of your car.

Thanks Rudeney , I updated my location . I am in NYC . I am calling around to see if anyone has the system . Thank you so much for your help . I thought that icarsoft being made for Mercedes had all the correct codes .

Hi, I know I'm a new guy on this forum but I just replaced my intake manifold tumble flap lever because of an intake runner position fault . . . this could certainly cause a lack of power or hesitation upon acceleration. I believe this is a common problem on the W209. Just my 2 cents.

Also, just between us grown ups . . . there is no need to be nasty when someone does not understand. Just change the channel, no worries we'll collectively figure it out. That's what these forums are for, to help each other understand. We're not all geniuses at everything. I can build a satellite dish from a coconut shell but would probably get hit by a bus crossing the street in NYC.

irokdastar

Hello Jepaul , Thank you for the help . Do you have a V6 or V8 ? I know its common on the v6 but I dont think I have them on the v8 engine . Or am I wrong about that ?

Rudeney

The intake manifold system on the M272 V6 and M273 V8 is the same, except that there are two extra ports for the two extra cylinders on the V8. So yes, the same tumble and swirl flap actuator problems affect both.

irokdastar

I have a 2004 clk 500 I have the M113 Engine . Do they have the same flaps like the m273 ?

jepaul

I don't believe they have the same arrangement of the flaps but there is some swirl flap motor or sensor attached to the manifold . . . at least that is what my mechanic friend thinks. He's not a Merc specialist so he does not know the exact engine configuration. If this is not the problem you might look at the EGR or find a shop that has the right code reader. That should not be a daunting task in NY.

Rudeney

There are two vacuum actuated movable components in the M272/M273 intake manifold. It has variable-length intake runners and swirl flaps. The intake runner just change the overall length of the path the air travels through the manifold. A longer path causes the engine's intake stroke to work harder and thus create more torque, so at low RPM,s you get a loner path. At higher RPMs where efficiency is needed, you get a shorter path. The swirl flaps crate both a restriction in intake airflow (thus more torque) and turbulence for better fuel/air mixing. At low RPMs, the swirl flaps are engaged, but at higher RPMs they are retracted for a more free-flowing intake.

The M112/M113 engines only have the variable-length intake runners. They do not have swirl flaps.

The reason for swirl flap failure is from a buildup of "varnish" and "sludge" from the PCV system. It collects on thes flaps and makes them more difficult to actuate. Repairing broken levers is just prolonging the death of the manifold. If the plastic swirl flaps themselves crack and pieces are sucked into the cylinders, you can have catastrophic failure. The best repair is a new manifold.

Hey everybody, my iCar unit just saved me some dealership $$$. My CLK 350 just limped home from the grocery store, missing on several cylinders. Most prominent error the iCarsoft displayed was "tumble flap actuator" malfunction. Sure enough, I poke around with a long screwdriver and slightly push on the actuator rod, only to find that it isn't attached to the lever any more. Why? because the damned PLASTIC arm broke. Apparently this is a common failure since there is a plethora of upgrade kits available that supply you with a metal arm with a bearing at the pivot. As usual, Rudeney is spot on.

I decided to buy the whole manifold with new actuators AND an upgrade METAL lever and pushrods which I will change out before putting the manifold on the car. Wish me luck.
