A warning light I had never seen before came on in my 2006 Nissan Navara D40 auto. My Nissan dealer informed me it was the diesel particulate filter. They kept it for a week and did a forced burn, which didn't fix the problem, and I was told I was up for $3200. I told them I would like Nissan to come to the party with the cost, which I thought was reasonable because there is no information about it in the manual, but the answer was no. I have done some research and apparently on each trip you have to travel above 80 km/h. Do I have a case against them?
The DPF requires a certain drive cycle to do the automatic burn it must do to rid itself of the accumulated carbon. Your driving cycle obviously doesn't meet the criteria so the automatic burn hasn't been done and the dealer has attempted a forced burn in an attempt to save the DPF. In one sense you're lucky that it only cost $3200 as many people find they also have to replace the catalytic converters and the cost can climb as high as $6000 or more when that happens. You might have a case against Nissan, consult the consumer affairs people in your state and get their advice.
