We cover the Mazda3 across the BK, BL, BM/BN and BP generations. Engines include 2.0- and 2.3-liter MZR units, the Mazdaspeed3 2.3 turbo, 2.0- and 2.5-liter Skyactiv-G and the 2.5-liter turbo, with Skyactiv transmissions and i-Activ AWD.



The 2008 Mazda 3 belongs to the first-generation Mazda3 (BK), built for model years 2004–2009. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2008 model year.
Check the model year on your VIN: on a 2008 vehicle the 10th character of the 17-digit VIN is “8”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 18 years old, a 2008 vehicle is in the age range where wiring, rubber hoses, seals and corrosion repairs take most of the work, and where original factory information is hardest to find.
Same generation: 2006 Mazda 3, 2007 Mazda 3, 2009 Mazda 3.
