Where does air leak in Mercedes Benz W210?
Just be sure to check all possible places air can leak in between the cylinders and the ICV. This also includes the oil dipstick O-ring, the oil filler cap, valve cover gasket, PCV valve and also the intake manifold gaskets. Sometimes, the process of eliminating all of the leaks can be quite frustrating.
Why is my Mercedes Benz W210 running rough?
Many times, a lean running condition can be traced back to a cracked or torn boot in the system. A good quick way to check the overall health of the system is to take the oil filler cap off with the engine running. If the system is in good shape, the idle of the engine should drop and the car will run rougher.
What happens when the cooling fan fails on a BMW E60?
The cooling fan is responsible for maintaining proper engine coolant temperature and A/C cooling. When a BMW E60 cooling fan fails, the fan will not activate or only activate at high speed. You can check cooling fan operation by turning on your air-conditioning and listening for the fan to activate.
What to do when exhaust bellows wear out?
Replacing Exhaust Bellows Sterndrive bellows are rubber “boots” that seal out water around the exhaust, U-joints and shift cable, while allowing the drive to pivot and tilt. These can wear out and require regular replacement (see owner’s manual for service intervals). Boating Magazine

Why is MY BMW E63 making a rattling noise?
Problems and faults: BMW E63 6-Series coupe If there is a rattling noise from the front of the engine and the ‘check engine’ light illuminates, there may be a leak in an oil line for the variable valve timing system.

What kind of engine does a Mercedes W210 have?
This article specifically covers the W210 Mercedes with the M104 engine, however the concepts I’ll go over apply to nearly all fuel-injected gasoline engines. In a gasoline engine, the speed of the engine is controlled by the amount of air that enters through the throttle body. In a diesel engine, there is no throttle body.
Why does my Mercedes Benz have a vacuum leak?
This is due to the extra unmetered air flowing through the oil filler port. If there is no change in the vehicle’s idle, then you probably have a vacuum leak somewhere in the system. Don’t forget to check places where vacuum leaks may not be as obvious, such as the oil filler cap, the dipstick and also the valve cover.
Can a vacuum leak cause a MAF error?
Vacuum leaks and other air leaks in the system can cause MAF sensor errors. If you have a crack or leak in your air intake downstream of the sensor, then the MAF will be sensing less air than the engine is actually receiving.
Where is the vacuum line on a Mercedes Benz?
On the right (passenger) side of the engine, you have one vacuum line that runs from the exhaust gas re-circulation valve to the actuator solenoid on the front of the engine.
