Mazda 6 2009: Design fault in diesel engine?
Asked by John
I have been told the fuel filter on my 2009 Mazda 6 diesel wagon is faulty and will cost $2000 to fix, but worse that the injectors are faulty due to a design fault and will cost $7000 to fix. Is this a common problem, or am I being conned?
Answered by CarsGuide
30 Oct 2015There have been reports of problems with the CX-5 and some other Mazda models of fuel contaminating the engine oil through the DPF filter. Mazda claim to have a fix for that problem. I would check with your Mazda dealer so see if your car is one of those affected.
