2007 clk550 code P0025
 

My car threw the P0025 code today.
So I have been reading for a couple of hours about the code. I can't find out for sure a fix. Some say it is the front cam sensors, and some say it is the side ones.
My car threw the code, and I reset it and took it for a long drive. The code never came back, and it is still clear. Is this a urgent problem?
It has 116 000 km and I recently changed the plugs. They looked nice and tan. The idle is a little rough, but nothing serious. There is no hesitation to speak of.
It seems to have lots of power. I just purchased the car recently and only put about 500 km on it.
I was thinking of changing the oil because I noticed a Canadian Tire oil change sticker on the window. I don't trust CT for doing any work whatsoever. Is Mobil 1 0W40 Euro Spec the proper oil for cold climates?
Thanks for any help in advance.

Use this to lookup the DTC(s) corresponding to that generic OBDII code:

You will see it's DTC 0064. Now, check out Scenario 2 in this TSB:

You need to replace the solenoids on the camshaft adjusters (a.k.a. cam magnets).

Thanks Rodney.
Is this what I need?

I might as well change them all because shipping and duty are a killer, not to mention the exchange rate. I pretty much double what the price is and it's pretty close to what I pay.

Yes, I would change them all. And that kit looks like what you need, for a good price.

Thanks for all the assistance, you are a real wealth of knoweledge.

So I changed the magnets, but the ones that were in there were the upgraded ones. Do you think the cam magnet wiring recall wold have something to do with the trouble code?

Should I just drive it now and see if any codes pop up? Or do you think I should go in for the wiring recall? I hate taking my car to any mechanic. I like to do the work myself. I asled if they would just give me the wiring and they said no.

Is there and actual recall for wiring? I did not realize there were any recall for the CLK. Now, there are "TSBs" but those don't call for post-warranty coverage.

I don't think that throws any codes. It was for oil leaking through the connector or something.

Acording to the benz dealer in Canda. Recall they said.
