Sorry to dig this old chestnut up but I am needing to do this on my ML350.
I assume I should replace the camshaft sensors at the same time as the magnets?

Camshaft position sensor solenoid magnet DIY
A P0015 code started last month on my 2007 S550. After one reset with my OBDII scanner, the CEL came back after a week. Not wanting to have this get worse, did some research and found the following which prompted me to jump on this DIY repair for an original solenoid magnet that should be replaced with an upgrade.
Purpose
The camshaft sensor is magnetic device with a solenoid. It gathers and sends information about the car’s camshaft speed (and as a result the position of each piston) to the electronic control module. This information is received by the computer, which then uses this data to further calculate the time of ignition and the timing of fuel injection required by the engine. Progressive problems with these sensors are:
1. "Check Engine" Light
The first symptom of a failing camshaft sensor manifests as a warning from the car’s control module. As the camshaft sensor fails, the computer sends the driver a warning sign via the “check engine” light on the car’s dashboard. When the check engine light first comes on, the driver has enough time to service the car and replace all faulty parts, including the failing camshaft sensor. However, if you ignore this flashing light for a considerable time, it could later lead to engine trouble.
2. Disrupted Driving
Another symptom of a failing camshaft sensor is experiencing constant disruption while driving. If you are experiencing symptoms like frequent stalling, poor idling of the car at 500 to 600 rpms, a massive drop in the rpms slowing down the car to a crawl, a noticeable drop in engine power, poor mileage, abnormal acceleration activity, frequent stumbling, etc., it probably means you have a failing camshaft sensor that needs immediate attention.
3. Ignition Trouble
If you ignore all of the above symptoms, you end up with one that really can’t be ignored—no ignition. Remember, as the sensor begins to weaken, so does the signal it transmits to the car’s computerized control station. If you let the problem carry on for too long, the engine will suffer from a “no spark” situation. Once the signal switches off, so will your engine, thereby stranding you.

Yeah I did mine without removing the cooler.
