Mercedes-Benz C220 CDi (2011 W204) - Diagnostic Code - lilley

Yellow engine diagostic lamp stayed on over two days at each and every start. It then cleared; a week later it has not recurred. I have had the codes read by M-B of Poole, It is P200671 The charge movement flap (cylinder bank 1) is jammed closed. The actuator is blocked. Status S. They want the car back for further investigations. The status of regeneration is given as 'Normal operation without regeneration of diesel particulate filter'.

What happened and what is the cure please?

Most modern diesel engines have various flaps in the air intake system that alter the flow and swirl of air into the engine depending on speed and load.I would guess that one of these has become stuck and not able to move freely.Access to these often requires removal of the inlet manifold.hth

The car has done 17,700 miles since new in my ownership. Presumably in the inlet manifold the flap cannot be jammed with carbon so it must be a manufacturing problem.

Would you agree?

If the car is a 2011 it is still within the 3 year warranty providing you have maintained it correctly.

Just take it to your nearest dealer and let them sort it for free.

And if you are doing relatively low mileage in it you are probably slowly strangling it to death with crud from the short runs you are no doubt doing.

Far better to trade it for a petrol as once the warranty expires sorting out issues like this will soon get very expensive.

I've been there with an X type diesel which soon told me the short runs were killing it. I got rid before the warranty expired.

Whilst it is possible the intake manifold air flaps could have a manufacturing fault, I think the probable cause would be lack of use given the relatively low mileage. As has been mentioned, if the car is used for short, stop / start journeys it won't get up to the optimum temperature and all the oily gasses that get recirculated through the EGR system condense in the intake manifold and gum the flaps up with the sticky carbonised mess.

Also, there is the risk that the DPF will eventually block up with soot / ash. Regeneration is automatically carried out when the pressure differential sensor(s) sense the DPF is getting full and as long as certain parameters are met, there is no problem. It usually takes a drive cycle of approx 15 - 20 mins at 50 - 60mph at around 2500 - 3000rpm CONSTANTLY.

If these conditions are not met, regeneration is aborted. After three aborted regen's, you usually need a forced regen using manufacturers diagnostic equipment as the soot in the filter is deemed unsafe to burn off under normal conditions. Ignoring this means a new DPF and then things get expensive !

Not that load of old nonsense again. You do not need to be revving the engine that high to carry out a regen. On our old BMW 118D and our Ceed CRDi regens happily complete with the revs between 1500 and 2000 for about 20 minutes, in truth they complete faster at these revs than higher ones. It tells you all about regens in your handbook, all makes are slightly different but the BMW and Kia have been pretty much identical.

you are quite correct, italian tune ups dont work with a DPF

low speed, low rpm, low throttle openings but a slight gradient helps.

The higher the revs the more carbon created, the faster you go the air ram effect cools the exhaust.

Gently does it as they say. Having carried out live testing on regens its very interesting to see how driving gently reduces the soot content but thrashing it increases it !

The car had done 2 x 100 mile trips the previous day to the initial problem on Shell standard diesel fuel. The car is used for mainly longish trips then stands for a few days.

Would premium diesel fuel be a good idea?

Sorry, I cannot agree with any of your comments. Did you get this information from Wikipedia by any chance ?

Having carried out numerous regens on various makes and models in the course of my work as both a VW main agent tech and now as a tech in an Indy VAG garage I have never heard such nonsense. Driving slowly at low RPM is the main cause of premature DPF blockage so how can your advice possibly be plausible ? You need to get the exhaust gasses hot enough to successfully burn off the soot content which will not happen at low speeds or low RPM.

When using either the VW VAS or Bosch KTS diagnostic equipment to carry out a regen, the programme insists that the road speed and RPM is within the range I quoted earlier. In fact, if the speed/RPM is not kept within this range for a duration which is dependant on soot content, the regen will abort. The software that governs regeneration will not allow it to commence if these parameters are not met, plus the heat generated ( around 600°c ) inside the DPF dictates a good airflow to keep the underbody of the vehicle safe from possibly catching fire which blows your "air ram cooling effect" into the water I'm afraid.

Back to the original question, I would suggest the OP gets the car booked in for further investigation. The flaps may be gummed up or the actuator itself may have started seizing so the only way to be sure is to get it looked into first. If the car still has some warranty remaining you may well get this for free, if not, it's worth trying to get some goodwill contribution ?

"Sorry, I cannot agree with any of your comments. Did you get this information from Wikipedia by any chance ?"

Not wiki Im afraid, 40 years experince in the trade all day every day dealing with diagnostics , testing & training !

If your working on VAG cars , put one in regen mode & drive with live data & watch the soot particle content when you thrash it ! IT RISES ! run at approx 1900-2200 rpm at around 40 has the quickest percentage drop ! if you increase the speed much above 50 you will see the soot particle content remain the same to a degree !

You will also find now that many manufactures are stating in their handbooks to drive within a certain speed range ( normally around 40mph )

Who said anything about "thrashing" it ? Since when has driving at 2500 - 3000 rpm and 50 mph been classed as that ? As long as the regen drive is within the pre determined parameters set out by either the car ECU or the diag tester, regeneration will be successful. We'll just have to agree to disagree.

In the OP's case, I wouldn't be chancing it and hoping the fault fixes itself. This engine is the OM651 and has quite a complex emissions control set-up - either take it back to the MB dealer or find a good independant MB garage. Either way, leave it and you may cause more damage.

M=B Garage have had the car for two days, actually turned out to be one, for 'further investigations'. No fault was found and nothing was stripped or replaced. The car has not suffered a second occurrence. Would you be happy?

hello there

I have W212 CDI E220 and I face the same error code by dignostic with Xentry program.

my car in winter time when I start the car it will run normal but when I engaged the D drive or

reverse the car will start , in hard hard way, shacking. it shack like 1 or 2 cylinder is off.

so I took way to solve this problem in temprory. the way is warming up the car more then 10 minute. in this way the car can drive either drive possition or reverse .but one thing in high RPM, the engine is not pullying ahead becuase the engine work either air or fuel not coming ( cuttung).

I took off these items:

manifold ( located beside the engine of motor ), throutle( located down ), cables, valves ( change ocer valve), reciever air tank of vacum system, pipe fuel (which coming from high pressure pumpe to common rail), water inlet ( from thermostat to block engine), thrmostat, rubber hoses for vacum system,EGR, BAypass valve of EGR,Pipe ( from EGR to Manifold , etc,,,,,,,,

what I found: bad, in very bad accumilate carbon in all manifold connections, pipes , EGR system etc,,,

what I did, I cleaned all manifold connections , EGR , pipes, where carbon is present I cleaned with special cleaner ( like CRC throutle cleaner and some by gas )

parts which cleaned by gas, after I cleaned with detergant and I blow out with air.

I gather all parts back

I start the engine but the same issue

my reason to do all these actauly for finding the leak of diesel and water of coolant. while finding the leak I found the carbon present in every where. so that I took alll parts for cleaning .

the problem is still there.

by the way this almost happened in winter sesson not in summer.

'Warming up' a car for a few minutes before driving is the WORST thing you can do, especially for a modern diesel. An engine warms up quickest when used. An engine idling from cold uses more fuel, will create more carbon/soot in the system, and will 'clog up' even sooner.

hello RobJP you said the worst think is to warm up the car ( engine). do you know what is will happen if I didn't this it will :

1- soon you guage the gear to drive postion the car (the engine) will shake like 2 cylender is missing ( 2 cylinder out ). you can't drive the car.

it will take time to come normal after warming up 11 minute
