The light on your FAP is on and you do not know what caused the problem. The FAP is mainly found for vehicles Diesel, even if they are now found for petrol vehicles. Before launching into repairs for the Suzuki Grand Vitara Xl-7, it is wiser to understand where this malfunction comes from. How does a FAP work? Why does the indicator light come on? What are the most common concerns? In this article, we will give a point by point overview. 
What is an FAP on your Suzuki Grand Vitara Xl-7
As its designation presages, it is used to filter out microscopic molecules harmful of your engine block. These kinds of molecules are so tiny that they easily enter your body. For your information, it is Peugeot who developed this FAP. Your catalyst has the role of reducing the dose of molecules generated from the engine, then the particle filter collects the rest. It is therefore fundamental to have an operational FAP if you no longer want the Suzuki Grand Vitara Xl-7 to pollute.
Why the FAP indicator light on your Suzuki Grand Vitara Xl-7
The FAP of your Suzuki Grand Vitara Xl-7 is clogged
Indeed, this is the most common problem. And that's normal, the particle filter becomes clogged as time goes by. The molecules pile up and then block the evacuation of exhaust gases. Normally, the particulate filter on the Suzuki Grand Vitara Xl-7 is expected to purge on its own and remove clumps. On the other hand, if this one is particularly old it will have to be replaced by a new one.
An electronic problem
The concern with these LEDs is that you are in no way certain that there is a problem. In practice, it sometimes appears that an indicator light comes on while the Suzuki Grand Vitara Xl-7 works without problems. The particulate filter has several electronic sensors which send the warning to the dashboard. If these probes have a problem while the particle filter is fine, it remains plausible that the indicator light is on.
What to do if the FAP indicator on your Suzuki Grand Vitara Xl-7 lights up?
To start, it is completely prohibited to remove the particulate filter from your vehicle! It is punishable by law. You can check the sensors to see if they work perfectly. If these ever work properly, the malfunction must come from the FAP. If it is dirty, you have the possibility of repairing it by driving on high speed for ten minutes. Without exaggerating, it could damage the car. We advise you to drive to 3000 rpm. The heat from the engine block will therefore burn the stored soot and purify the particulate filter. If this combination does not work well, it will have to be changed.
Conclusion:
Your damaged particle filter will pollute and reduce acceleration. It is therefore essential to take care of it. Write a comment in case our file has been useful. Enjoy the road!
