This is probably a bad idea... but have any of you folks tried using chemicals to clean a blocked DPF?
After a few weeks of driving around town with little if any motorway driving (I know, my bad) my "DPF (Check System)" warning light has come on and my turbo has stopped kicking in (like it usually does at c. 2000 RPM) on my Honda Accord EX I-DTEC from 2008.
My local Honda dealer want to charge me £150 to do a regeneration. But my local garage is suggesting that I go to Halfords and ask them what the best chemical is, put it into my tank and drive it 50 miles at fairly high revs - i.e. "2000 to 3000 RPM"). Luckily my tank is fairly empty - c. 100 miles left in the tank so I should be able to create a fairly high concentration of any chemical additives that I put into the tank.
6HAD thinks that this is a bad idea. But have any of you tried using DPF additive chemicals yourselves?
e.g. Have you tried any of these?
