    Diesel particulate filter specialists

    Your car’s Diesel Particulate Filter (DPF)  sits in the exhaust system and filters harmful carbon particulates produced in the combustion cycle, preventing these particles from being released into the atmosphere.

    First fitted to diesel vehicles in 2007, the DPF has been causing confusion and, in many cases, expensive repair bills for drivers due to a lack of knowledge about the system.

    The filter is designed to deliver an 80% reduction in diesel particulate and soot emissions by trapping the particles in the filter itself.

    The engine control unit (ECU) monitors the saturation level inside the filter, and when it reaches a certain percentage, it increases the temperature inside the exhaust to ‘burn off’ the particles.

    If your car’s DPF hasn’t regenerated and has become ‘blocked’ you’ll see a warning light on the dashboard and need to take your vehicle to a diesel mechanic immediately.

    Our services include:

    • Diesel engine diagnostic
    • Troubleshooting
    • Diesel engine repair service
    • Diesel engine maintenance
    • Engine replacement
    • Major engine restoration
    • Diesel engine spare parts
    • DPF maintenance
    • Repairs and maintenance of engine-related parts, e.g. automation, alarms & controls


    Diesel engines are unique in that they use mechanical combustion to ignite the fuel and work quite differently from other engines, which means that it requires a high level of expertise to understand how they function and to conduct successful repairs and servicing.


    At Port Phillip Automotive, we are also specialists in dealing with Diesel Particulate Filters (DPFs), which prevent harmful carbon particles from being released into the atmosphere. These filters are situated in the exhaust system of your car and must be handled with care. During the combustion cycle of diesel engines, carbon particulates are released and the filter is designed to reduce these emissions by up to 80%. However, over time the filter may become over-saturated or blocked, in which case you will see a warning light on your dashboard. When this happens, bring your vehicle to us at Port Phillip Automotive for expert diesel servicing and peace of mind.

    I was down the peninsula visiting family when my car wouldn’t start one evening. Chris from Port Phillip Automotive came and checked out the car within 20 minutes, found the problem quickly and the next day had fixed it for me. Fast, reliable and great service

    Have been through many different mechanics over the years. Chris and Port Phillip Automotive have been the best by far. An honest company that cares about their customers and always does a great job. Will definitely continue to use their services.

    My Nissan Patrol kept having engine check light come on and it would constantly go into limp mode. The car had logged several codes and Nissan told me that the car would cost approx $6000 to repair. I got a second opinion through Chris, and within 3-4 minutes he found my supposed $6000 issue, it turns it out was a loose fuel line and it was a simple fix with a $1 hose clamp. Very happy with the outcome!
