I did some googling and found you lot, who seem to have similar problems to me! Not sure if that's a good thing or not
Car: 56' reg Mazda 6 2.0d Sakata
Story: I did a 180 mile trip today, and after about 150 miles, the car felt really sluggish. Hills on the motorway were ridiculous - foot to the floor, even dropped down to 4th at 70mph and it was struggling. After 160 miles or so, the DPF light suddenly started flashing (it wasn't on solid before this, just flashing). I did remember reading the manual so I slowed down and kept it around the 3krpm mark but it made no difference. At about 165 miles, the engine management light came on, and I thought "oh crap, its actually broken". It's a saturday afternoon, no garages are open (there are very few near me anyway!) so I limped it to KFC not far from home. Let it sit while I browsed the manual and ate some chicken, then pinched some napkins so I could check the oil level - it wasn't much below the X mark on the dipstick. I drove it the remaining 3-4 miles home and parked it up. It's dark now, so I can't look at anything until tomorrow, but it seems the symptons I've had are in a different order to most :s
Tomorrow, I plan on following the guide on Tips and Tricks for MAZDA 6 (GH) 2.0D MZR-CD (RF-Turbo) 2007 - 09. - www.cdn.dk
1. Change oil and oil filter.
2. Warm up the car, take it for a drive.
3. Clean the DPF. takes about half an hour.
4. Reset for oil change.
5. Reset the DPF.
6. Calibrate the injectors.
If that doesn't work, it looks like I'll be either hunting for a replacement DPF+cat, or finding somewhere who can remove it for me and remap the ECU at the same time (not gonna be easy around here!).
Anyone got anything else they could throw in? I'm new to diesels, but not new to cars/engines - I carry out my own oil/filter/coolant changes regularly, I've just broken up my old Mazda 323F (including removing the engine, and I didn't even use a hammer) so I'm not alien to everything, but diesels are new to me!
Oh, the best thing? I've owned this car for 20 days now
This is a good start!
