🎃 Mazda 3 2.2 Diesel Engine Problems

2.2 Mazda engines are well known for dpf and oil dilution issues. So if I was you personally I'd get the dpf gutted and get it and the regen process mapped out of the ecu and be done with them. This should resolve the issue quickly and allow you to have an operational car. Before we discuss the Mazda CX 5 problems let’s see the fuel economy numbers. The naturally aspirated engine is delivering 25 mpg in the city, 31 mpg on the highway, and 28 mpg combined. The turbocharged version is delivering 22 mpg in the city, 27 mpg on the highway, and 24 mpg overall fuel economy. Hi, I have a problem with my Mazda 3 2.2 Skyactive D: when accelerating in 5th or 6th gear, between 130 and 150 kph (but I guess it is linked to the rpm) , there's an annoying vibration coming from the engine compartment: the entire car starts vibrating and looks like the engine is struggling to deliver the power, it goes away when realising the throttle, or when speed is outside the 130-150 Both Mazda 3 engines have a timing chain instead of a timing belt. The timing chain doesn't need to be replaced unless it's stretched or there are some other issues with it. Fuel economy The EPA rates the 2004-2008 Mazda 3 with a 2.0-liter engine and automatic transmission at 23/31 mpg (10.2/7.6 L/100 km) city/highway. Common problems with this engine include cylinder head failure, valve stem seal failure, and cylinder deactivation failure. All these problems affect different VIN numbers. The most problematic are the model years between 2018 and 2021. Older engines do not have these issues. 20,143 posts. 251 months. [report] [news] Monday 20th April 2015. The older Mazda diesels suffered badly from oil dilution due to the DPF regen method. Owners tend to find the oil level increasing Removed injector and found number one injector seal to be leaking causing excessive carbon build up/sludge in engine causing major engine damage. Replaced engine, number one injector and turbo assembly as per Mazda Australia's instructions. Cleared all malfunction codes.

Some might be surprised that the Mazda 3 2.5 Turbo can get to 60 mph in roughly the same time as the old Mazdaspeed3 even though it produces 13 fewer horsepower. The secret lies partly in the gearing and partly in the design of the turbocharger. The Mazdaspeed3 used a fairly traditional single-scroll turbocharger, so lag was noticeable. xNma.
