Will it store a code showing its done a regen?And you havnt meantioned all that fuel you saved at 60mpg, you then pour down the exhaust on each of the exhaust strokes to get the sost glowing and then if you slow down below 40 mph it was all wasted and it has to start again!
as said I had one customer with an ashcan hehe that was spell check changing qashqai! quite apt so left it, her commute was just at the point when the regen cut in then she reached work , Literally took a few weeks and back again I cleaned it 4times with a power wash etc etc then I 'properly' cleaned it out!! hasnt missed a beat since.
