Hi All,

 

Is there an efficient DPF cleaner liquid which I can use in fuel, before fueling? 

DPF light on my car is never blinked or switched on, but the smell of the exhausted gas is really smelly. When I bought my car it was not smelly.

I always kept the DPF regeneration.

Which is the best DPF cleaner liquid which really efficient?

 

Thanks in advance.

What's the ash loading on the DPF? It may be that your DPF is full of oil ash and needs to be replaced.

I don't know it is full or not, maybe yes, but the regeneration should be burn the ash.

If the light switched on permanently in that case, I should be replace the DPF. is it correct?

I just would prevent the exchange of DPF, with cleaning of it at first, because a new DPF is really expensive.

A regeneration is only able to burn off soot, leaving an amount of oil ash. This is why DPF filters have a service life as once it's full of oil ash it'll need replacing.

 

Personally, I wouldn't add any DPF cleaners on a CR engine as I doubt they are needed. It's well designed with the DPF is close to the engine so should be hot enough to burn off the soot on a normal highway run.

 

If your engine is in good condition and not burning oil then the DPF should be fine for 200000-300000km assuming the car is able to regen when needed.

Just go drive a few miles at 60 in 4th.  If that doesn't burn it off there may be something else wrong.  My car quite often stinks but being a taxi it does a lot of small runs so not really ideal for emissions strangled dervs.

 

A garage should be ale to do a forced regeneration if it is not doing it itself.

 

Mine will do a regen in the middle of town, once amusingly at lights at 3am with my colleague behind me.  Looked like an 80s pop video all lit up by his Xenons

You can get the DPF cleaned, done here on a Skoda Octavia https://www.youtube.com/watch?v=UsIq1dmdASE

Give it a good long run , at operating temperature for a few hours on the motorway
