Has Dunlop ve302 been discontinued?

Dunlop ve302 tires have not been discontinued. Here is some information about tires: The role of tires: Tires are the only components of a vehicle that come into contact with the ground. The contact area of a car tire is approximately the size of a human palm. Within such a small area, tires must withstand enormous forces from various directions to ensure good ride comfort and smooth driving for the vehicle. Tires are also crucial for the safety of drivers and passengers, playing a very important role in vehicle usage. Tire selection: For those prioritizing durability and versatility, Pirelli STR is a good choice—a semi-urban, semi-off-road SUV tire suitable for various road conditions. If handling performance is a priority, Bridgestone HPSPORT, a sporty urban SUV tire, is recommended. For those who value comfort, Continental CCCUHP, a comfort-oriented SUV tire, is an excellent option.

Where is the carbon canister purge solenoid valve located on a BMW X5?

BMW X5 carbon canister purge solenoid valve is located on the left side of the engine, next to the intake pipe. Function of carbon canister purge solenoid valve: The carbon canister purge solenoid valve is a device installed in cars or motorcycles to reduce air pollution caused by fuel vapor emissions while improving fuel efficiency. Principle of carbon canister purge solenoid valve: When the engine is off, the vehicle's activated carbon canister begins absorbing fuel vapors evaporating from the fuel tank and securely locks them within the micropores of the activated charcoal in the canister, preventing the vapors from being released into the atmosphere. When the engine starts, the absorbed fuel vapors in the canister are then delivered to the engine as fuel.
