DPF and Regeneration Issues?

When the oil burns in an engine, naturally it emits some gas but some of these gases could be harmful to a DPF. Low SAPS oils are specifically designed to be low in Sulphated Ash – a by-product of combustion that can cause the ‘mesh’ structure in a DPF to become irreversibly blocked. Such oils that are not low in Phosphorus and Sulphur can also have a significant, detrimental effect on Catalytic Converters – so the issue of getting the right engine oil is relevant to petrol and diesel vehicles alike.

hello

First post but I have been lurking around in the background for a while now. I am a previous member SEAT CUPRA. NET having owned a 1.6 CR Seat Ibiza Sport  . Great car however the problems with the DPF were unreal ! The car was eventually sold as it was going to cost far too much money to have sorted out everytime the DPF decided to act up for a brand new car with less than 10k miles. I eventually took the plunge and went for a one owner Mk5 GT TDI 170 knowing fine well it was a DPF model. I was advised by the Indy that i use to run it on Super Diesel and i can honestly say I have never looked back. Never seen the DPF light once compared to everyday with the ibiza and only rarely does it go into regen mode ( if it does its only 10 mins or so) .

It would seem to me that these mystical things called DPF's are just that and that they cannot be predicted however I would highly recommend using better fuel or run a diesel treatment through the system to either promote regen or keep everything sweet under the hood and in the exhaust.

Thanks for all the tips. A few questions though.
Firstly, how does removing the DPF affect the running, emissions, warranty etc? Do you think putting just super-diesel in rather than the standard stuff would make any difference?
The car has done just under 60k, and has been well looked after. The dealer did tell me to think about selling it when it gets close to 100k as that is when the DPF's eventually give up and at £1500 I'm not sure I want to be the owner when it does. Apparently the Mk 6's don't have any DPF issues according to the dealer!

i had a Leon PPD PD170, Quite alot had been done to it, Darkside Developments EGR Delete, Milltek DPF Delete pipe, Scorpion Cat-Back (No Boxes at all) amongst other things.

Ran several DPF Delete maps on it

JBS/Custom Code "Wild" DPF delete map (Stuttered alot)
JBS/Custom Code "Wild" V2 DPF Delete map (stutter was solved)
Shark Stage 0 (felt suprisingly good)
Shark Stage 2 (went very well)
Shark Stage 2+ (this was not for road use because of the amount of smoke)



Went though 2 MOT's fine, never broke down, and was a great car for me, only sold it because i wanted 300+bhp and at the time Darkside wern't releasing Turbo kits for the PPD PD170 so i bought a 2.0Tfsi
