Hi,

I am the owner of a 2006 CLK350. I have had it for a month. I keep getting these error codes, P2006 and P0410, after clearing the codes. The codes show up after 300 miles or more. I have read some threads that say it might be a pump. I have no idea where the pump is located. Can someone please point me in the right direction with a fix please.

Here are the descriptions of these codes:

P2006:
0522 Diagnosis of tumble flap 'Intake manifold' : Open circuit of sensor lines / Tumble flap
shafts stick in the nonactuated position.

P0410:
0810 Malfunction of secondary air injection at right bank of cylinders (function chain)
0814 Malfunction of secondary air injection at left bank of cylinders (function chain)

The tumble flaps are inside the intake manifold and are used to vary the length the path the airflow takes. This may require replacement of the intake manifold.

The secondary air pump is located on the front of the engine. It's an electric motor that blows fresh air into the exhaust system when the engine is cold. It may be defective and need to be replaced, or it could just be a bad fuse/relay (fuse 65 and relay O on the front SAM, under the hood).

I also have a code for the SAS pump. I checked the pump - works fine. On my
2000 CLK 430
Where are the fuse and relay? I have seen several YouTube vids and other similar things which show newer cars - but they don't seem to match the location of my fuse and relay for the SAS pump. Some help please?

Your car is a w208 - you should post in that forum.

Thanks for the assistance. I will check the fuse. I guess i will have to buy a new intake air manifold. Ouch...

Not necessarily, there are kits sold aftermarket that deal with the problem. The tumble flap actuator breaks (it is plastic) and does not operate the flaps. The intake manifold still needs to be removed to do the job but it is a helluva a lot cheaper than the $1,800.00 you are about to be told by the dealer to install a new manifold.

Damn, wish I had known about the repair kit when mine went bad

Thanks for the info. Where should I look for the kit. Again, thanks for the help.

This is an old post but I'm getting the same 2 codes on my 2007 clk350. If you do see this and can let us all know if you ever fixed the issue and what you did to fix it.
