Do petrol cars have particulate filters?
Do petrol cars have particulate filters which can clog? I have a Hyundai i30 2018. A light came on the dash board and when I took it to the workshop they said its particulate filter so I have to run it on the motorway to clear it. I did that and the light went off.
Three months later the light has come on again. I thought its only diesel cars that have particulate filters. I used to have a diesel car and because of that I changed it to petrol, because I drive it mainly in the city. I need help please.

Some petrol vehicles are fitted with particular filters, in respect of Hyundais this is typically those fitted with Gasoline Direct Injection (GDI) engines.
Hyundai in the US issued specific guidance on how to perform a regeneration if the light is illuminated, which is to drive over 50mph in third gear, accelerate to 4,000rpm, release the accelerator for five seconds and accelerate again to 4,000rpm, and continue this process until the warning light goes out.
If this does not clear the light within 30 minutes or the warning light begins to flash, you should take your car to a Hyundai dealer or independent Hyundai specialist for further diagnosis.
