Hi there
Just joined forum to canvase others view's on the apparant problem with the Diesel Particulate Filter on the Mazda 6 diesel.
I have a 07 plate car.
7000 miles after first service which incidently cost a fortune! the engine oil rose up to the X mark on dip stick so as advised by manual took it to dealer who charged another £110 to change to oil and filter and clear the DPF.
I queried why this was happening and was told I was driving the car too slowly and the car was trying to clear the filter by injecting more diesel (on the exhuaust stroke) into the engine to raise the exhaust temp. Some of this diesel gets past the pistons down into the sump hence the oil level rising!!!!!!!!!
At the same time they updated the ECM and fitted a modified dip stick. The new dip stick has a lower normal full mark (Was told 1 litre less oil was now in sump) giving more room for diesel in the oil before it reaches the X mark and so should last the 12500 miles between services before the level rises above the X. ECM upgrade caused the car to judder/stutter under certain driving conditions so had to go back to dealer for more modifications that seem to have cured this
I wrote to Mazda asking various questions including how I should drive the car to keep the DPF clear. They replied and quoted a driving proceedure that they say is in the Hand Book but its different from whats in mine so they have obviously had to change things. Have written back pointing this out to them and also that I do infact exceed their driving recommendation every week with a motorway commute.
What are other peoples experience of this problem? My last 2 cars were deisels with DPF filters and had no problems with them. Also last car a 320d BMW was giving over 45mpg where as the Mazda struggles to get more than 40 on exactly the same commutes (BMW cost me £90 in servicing in 25,000miles of driving with the mazda already costing nearly £500 in 9000miles)
Very disappointed in car because of above as it is otherwise a good car. Yes I bought it cheap but Mazda did have a good reputation. My wife has a 9 year old Premacy that has generally been trouble free.
