Those errors are all indicative of failed camshaft adjuster solenoids (a.k.a. "cam magnets"). In addition to throwing errors, they can also leak. This is covered in scenarios 2 and 3 of the "balance shaft" TSB:

I'd replace all four of them. You can get them for about $100 (total). They come with new seals and are a fairly easy DIY. Also check the back ends of the heads for leaks. The left (USA driver) side has two plugs that often leak. The right (USA passenger) side has an oil centrifuge cover that often leaks. These are also inexpensive parts and fairly easy to DIY. The only challenge with the camshaft solenoids is that you will probably have to remove the oil cooler, which means replacing its gasket and draining the radiator. The cam plugs are easy - they just snap in. The centrifuge cover can be a bit of a challenge simply because it uses Torx bolts and there's not much room to work, so you'll need a compact wrench set for that.

Thanks a lot. Excellent. Will these work?

it is a 2007 clk 350 hardtop\coupe American left hand drive. V6.

Will I have to remove the oil cooler on this 07 clk350 to replace the magnets? If so, I'll probably take it to an indy and have them replace them for me. Thanks

That link does not work for me, but I see "Amason" embedded in it. Personally, I would not buy critical car part on Amazon or eBay as there is a proliferation of fake parts on the market. I don't mean Chinese branded crap, but Chinese crap that is made to look like an OE MBZ or OEM Bosch part - complete with boxes, labels,

Here is one source for genuine MBZ parts - they are an authorized MBZ dealer that has an online discount parts store:

This is the entire kit - 4 adjuster solenoids, an oil filter and the oil cooler gasket. Most of the time, you do have to remove the oil cooler to get the solenoid that sits behind it out of the head. It's not hard - drain a gallon of coolant from the radiator, remove a few bolts.

I can personally attest to this fact. I bought some "genuine" Hella headlights from Amazon. They came with all the right packaging, labels, etc... but the body shop that I took them to for installation quickly identified them as fake. When I called the company and explained what they were selling, they took them back and did not seem surprised that I was claiming that they were fakes.
