Petrol car with error code p246300

Particulate filter soot content to high. Is this error code right? It's petrol car thanks

Can you tell us how you arrived at that error code? The standardised codes are a letter and 4 numbers, sometimes after this they have a dash and then 2 further numbers. I know its only a detail but you've given 6 numbers with no dash.

Scan it yourself? What with (make/model of scan tool, which mode was the machine in)? Appear on a report/invoice from a garage? Which garage? Which car? "Its a petrol car" is drip feeding us info.

Maybe, maybe not.

P2463 is a particulate filter code.
The 00 is usually a subsection code and won't usually mean anything for a filter code like this, it's either working of isn't.
 
How did you get this code, what diagnostic tool did you use?
Sometimes the diagnostic tool can misinterpret codes.

What car/engine is it?
Most modern petrol cars have a soot filter these days (GPF or a FAP). They aren't just for diesels.
Petrol engine filters are passive rather than active filters like diesels.

These filters trap the particulates (soot is fuel that hasn't completely burnt) and will then burn that completely to ash and store it.
So eventually they all fill up with ash, but ash particles are far far smaller than soot particles so hold far more ash than soot.
It could be it's filled with soot which it is struggling to burn to ash, or just total full with ash.

With a diesel, it has to introduce more fuel into the filter (DPF) via a post combustion injection into the cylinders and then ignite that fuel in the filter to reach the required temp to turn the soot to ash, but in a petrol it's different.

The engine on over run will produce enough heat in the filter to turn the soot to ash.
Every time you take your foot off the accelerator, the engine injects no fuel but pumps out extremely hot gases, enough to burn the soot to ash. (hopefully) 

There have been reports of a few models/makes petrol engine suffering like this.
One of the more common ones I have heard about is the little 1.0T GDi in some MG's.
This direct injection petrol engine appears to be rather sooty and probably has a poorly sited filter due to packaging so the filter is short on heat, but writing that the dealers, importers and manufacturers will blame your driving.

As these filters are passive and regenerate differently than a diesel filter, there's little you can do except replace the filter.
Long motorway runs won't allow for the sort of active regen a diesel filter would.

I have a filter in my car, Renault call it a FAP and it's been trouble free for the last five years.

Ask garage then. They have the car in front of them, all we have is your posts.

That's the Renault unit I think..?  I remember seeing some issues on a Dacia forum about GPF issues so maybe try there or Renault forums?

PSA also use the same acronym, which is unsurprising to anybody who speaks any French.

It stands for "Filtre à Particules" - which is simply the French for "particulate filter"

Do petrol engines have particulate filters?

In summary, the short answer is “no,” petrol cars don't use a DPF. Diesel particulate filters are strictly for diesel engines.
