DPF and premium diesel

[Niall]

Here is an article about the use of premium diesel fuels and the effects it has on the DPF, problem is it in dutch:

Conclusion is that fuels like v-power, ultimate etc have a negative effect on the DPF, due to the higher burn temperature in comparison to normal diesel. More fine soot is produced which then clogs up the DPF causing it to regenerate constantly or causing the car to go into limp mode.

Best thing is to tank normal diesel when running a DPF, also when the car has any kind of remap the problem is exaggerated.

Diesel Particulate Filter or something very similar from memory.

These are fitted to the Leon FR TDI

Interesting.

I guess the dealers can't get out of warranty claims by saying you used non-approved additives either, as you bought the fuel from a normal filling station....

Interesting thread. I found my tuned GT TDI ran much better with ultimate and vpower a lot less smoke so was assuming that my new fr 170 would benefit from higher quality fuels - maybe i had this wrong! Save some money though- always good

so what about the mk1 cupras? or is it just the FR's?

It's only the Leon MK2 FR that has them i.e. cars with the PD170 engine...

I'm assuming any diesel with a DPF would be affected but the Mk1 would be fine with the higher quality fuels and you would get a benefit albeit at a cost.
