What could cause the Check Engine Light to illuminate on a Mercedes CLK 350 after the air filter were changed?

Presuming that the Check Engine light coming on is connected to the replacement of the air filters and is not a coincidence connected to some other problem, the possible reasons for the Check Engine light to come on are:

  • The air filter housings are not properly fitted or secured causing unmetered air to enter the system.
  • The air intake tube has not been properly secured thereby allowing unmetered air to be sucked in.
  • The vacuum hose was inadvertently knocked loose and not refitted.
  • The mass air flow sensor was not correctly plugged in.

The vehicle should be taken back to the shop that did the job so that these issues can be investigated and corrected.

Could the Check Engine light coming on in a 2010 Mercedes E350 soon after the air filters were changed be connected to the fact that the metal clip at the back of that air filter housing not staying in place?

The Check Engine light and the clamp not staying in place suggest that the air cleaner has not be correctly fitted to the mass air flow sensor.

What could cause the Check Engine light to illuminate on a Mercedes C300 after the air filter was changed and the vehicle runs perfectly?

Small issues in the installation of the new air filter like the housing not being properly secured or the air injection hose getting pinched can cause the Check Engine light to come on although there will be no effect on the vehicle’s performance. The air filter installation should be checked and the vehicle taken to a shop or auto part store that has a Mercedes compatible scan tool to have the code that is causing the light to come on erased.

Could the fact that a 2003 Mercedes C230 Kompressor stalled and will not restart after driving through deep water be a sign of major engine damage?

If water has entered the engine this can cause a hydraulic lock up as water will not compress in the cylinders causing the engine to cut out. This can cause severe engine damage. However, before considering this possibility, the air filter and intake should be checked for signs of water ingress. The intake should be cleaned and dried out and the filter replaced. If this is the extent of the problem, the vehicle should start.
