Signs of a Failing EVAP canister

Image
The canister purge valve, also commonly referred to as the purge valve, is an important component of your Evaporative Emission Control (EVAP) system. This system restricts the fuel vapours created in your fuel tank from escaping into the atmosphere by trapping them in a charcoal canister. When your engine begins to run at regular speed, the EVAP system slowly allows these vapours to be released into your engine, which burn like regular fuel. The flow of these vapours is controlled by your canister purge valve, which regulates when and how much of these vapours enter your engine. The canister purge valve is electrically operated, and is also referred to commonly as a solenoid. The most common purge valve issues are when the purge valve is stuck open or closed, or does not open at the proper time. The symptoms are listed below that may indicate your canister purge valve is not functioning properly. 1. Check Engine Light Is On The first sign of trouble for your canister purge valve is the

Causes of vibration above 60 mph of GL450 Mercedes Benz

GL450 vibrating above 60MPH


Vibration above 60 miles per hour while driving your GL or ML is caused primarily, by either a propeller shaft or the flat washer of the lower arm bushings.

Lower arm bushing will cause the vibration if:

  •          It’s broken
  •          You Changed the position of the flat wide washer: the washer on the big bushing of the lower arm supposed to be at the right side of the bushing. If it’s changed from this position to the front end of the bushing, it’ll destroy the alignment of the lower arm and the bushing. This, if you're accelerating at a high speed above 60 mph, it’ll draw the iron in the bushing to the chasis of the vehicle. This you’ll feel as a vibration while speeding. This situation usually disappears when you lower your speed below 60mph. 

lower arm bushing washer will be at the right side of the bushing, not left  

Propeller shaft and driving shaft

A broken driveline of the propeller shaft can cause the vibration of GL450 above 60mph


  •          They’ll be a vibration if there’s no grease in either the propeller shaft or the driving shaft
  •          If the bearing of the propeller shaft is broken
  •          If the cup of the driving shaft is worn out

Other culprits are broken transmission mounts, bent rim(s), bad tyres  and  bad wheel alignment
