Voyah, catalyst replacement in Golan.
Catalyst malfunctions are caused by poor fuel quality, engine breakdowns and mechanical damage to the ignition system. The procedure for replacing the catalyst depends on the car model and the Euro environmental standards. In cars of lower Euro standards, it is enough to cut the body, remove the element from there and weld the body. Starting from Euro 3 vehicles, it is also required to carry out some software work in the control unit.
