In actual fact, it is one of the most important parts that fight against the pollution discharged by your Renault Megane 3. It will convert these harmful gases into water or nonpolluting fumes. In order to convert these gases, the catalyst of your Renault Megane 3 a mesh of precious metals which, when the gases pass at high temperature, will break them down by chemical reaction . A catalytic converter can just work from 400°, it is therefore essential to avoid clogging the catalytic converter of your Renault Megane 3. If you are thinking of making sufficiently long travels to heat it up repeatedly (count more than 10 kilometres for the catalyst to reach the right temperature), this will allow you to optimize the life of this component and maintain ideal engine unit efficiency.

  • Switching on the engine light: : Following a clogged catalytic converter, engine light of your Renault Megane 3 may come on, do not hesitate to seek advice from our content to identify how to switch it off.
  • A faulty lambda sensor : The catalyst works in close connection with the lambda sensors downstream and upstream of it, they will analyze the air flowing inside it, if it is clogged the sensors will often as well have complications.
  • A metallic noise coming from the exhaust: In the event the catalyst is dead you should notice this noise which means that the ceramic is damaged.

Why you should clean the catalytic converter of your Renault Megane 3

Before we accomplish with the step you are likely most interested in, how to clean the catalytic converter of a Renault Megane 3? We will show you why it might be important for you to conduct this cleaning. In actual fact, a catalytic converter is a very expensive component (about 500 euros with the installation, the price can vary according to the engines). Furthermore to being no longer good for passing the technical control , you might be at risk of over-consumption of fuel . Finally, the last interest is that cleaning a catalytic converter is not that expensive and doing it repeatedly will save you quite a lot of money.

How do you clean the catalytic converter from its Renault Megane 3?

Finally here is the step that you are likely most enthusiastic about in this content, how to clean the catalytic converter of your Renault Megane 3? Know that this process is very simple, and that there are two approaches to accomplish:

  • Scrubbing the catalytic converter from your Renault Megane 3 regularly: This technique is specifically useful for people who principally do short trips . To do this, nothing could be less complicated, from time to time, make a long trip (about 30 minutes to enhance the efficiency of the process), thinking of making your engine go up in revs so that the temperature in the catalyst increases and it can be cleaned.
  • To use a catalyst cleaner: You can find some in a motor vehicle center for about 20 euros. All you have to do is add it to your fuel directly in your tank with about half a full tank. Afterwards you will have to drive on a long distance for at least 1 hour at mid-range by trying to go repeatedly at high rpm . If you can before and afterwards do an exhaust gas analysis to check that you have recovered healthier exhaust fumes after the procedure. You can conduct this procedure every 15 000km.
