This Mazda 3 was using a lot of fuel and running rough so we replaced the airflow meter  -  then the dashboard warning light came on so the owner brought it to us for some more diagnostics and help. 

Initial vehicle scan and diagnostics of the Mazda 3 

Using the scan tool, we monitored air flow meter data: grams per second and air temperature. Both readings were out of specifications. We diagnosed the air flow meter as faulty due to the air flow and temperature from the component being out of specifications.

We replaced the air flow meter and tested everything again - the air temperature was good and grams per second came in around 2 grams per second, all within specifications, and also during the road test all indicators were okay, the car was no longer running rough!

The vehicle returned to us approximately one week later with a warning light on the dashboard.   There were no running issues, that had been fixed  - just the light present on the instrument cluster.  We read the message  - P0171 (bank one system too lean). Intake air temperatures from the air flow meter were okay, grams per second were down.  We suspected there might be an issue with the new air flow meter that had been installed.  We fitted a replacement air flow meter for the customer and everything was okay!

But the vehicle returned with the same code, but this time the engine light was only coming on intermittently. We pico scoped the fuel pump and that showed us slight wear in two of the pump cells, so we the checked fuel pressure which was within specifications every time. We also checked the operation of the front air fuel ratio sensor, all okay.

So again we started looking at grams per second reading from the air flow meter and we noticed that the reading would drop occasionally. Suspecting a slight intake leak we filled the manifold with smoke to inspect for leaks -  yet there were none to be found.

After finding no EXTERNAL intake leaks we started suspecting an INTERNAL intake leak. When disconnecting and blocking the evaporative emission purge solenoid valve between the valve and the manifold, the grams per second reading rose to within spec. So we checked for a leak through the evaporative emission purge solenoid valve - there wasn't one. We reassembled the purge valve and hose to intake manifold with a clamp , all readings were within spec. A further test drive indicated no faults.

A few weeks later guess which car was back, yep, and the same code. Still going with the evaporative emission valve and internal intake leak theory we removed the hose between the purge valve and fuel tank, this time there was a huge intake leak, this wasn't happening last time we checked!!  Also, the scan tool showed that the purge valve should be closed. By blocking the intake leak all readings were within specifications, most importantly, the grams per second through the air flow meter had risen.

We found we could use the actuation tests on the scan tool to control the duty cycle of the purge valve. Finding the purge valve intermittently not shutting when commanded, even though the signal was getting to the purge valve from the engine control module, all okay, we suggested replacement of the purge valve. Once the purge valve was replaced we tested it with the scan tool, it shut every time we commanded it to...brilliant!!

We took the vehicle for a good long test drive while monitoring the purge valve duty cycle and grams per second from the air flow meter - everything was operating normally and whenever the purge valve was shut the grams per second was within specifications. WE DID IT. #CELEBRATIONS

Sometimes car diagnostics can be a tricky business -  sometimes there can be more than one faulty part and fixing the first one found can lead to finding more problems. Even experts like us sometimes need to use extra investigations and some out of the box thinking to solve the problem.  But the most important thing about this story - This customer's vehicle is now running smooth and no warning lights! 

If your car isn't performing as well as it should, or your warning lights are shining - give us a call at Blackwood dyno tune for expert diagnostics and service.

Auto Electrical servicing is one of the most important ways of keeping modern cars running efficiently and safely. You should always visit a qualified auto electrician to ensure your vehicle is maintained properly.

It is easy to spot an auto electrical issue when the worst happens. A car which will not start signals an issue with the battery, alternator or spark plugs. But what about when there are more subtle issues going on with your vehicle? There are warning signs which can signal that you need to make a trip to see an auto electrician or suitably qualified mechanic. Some of the top symptoms and causes of auto electrical failure include:

Faulty start due to worn out spark plugs.

Engine will not start due to a broken alternator.

Dead battery due to buildup on the connection cables.

Puddle under a car which will not start due to a leak in the battery.

Engine does not engage due to failed starter and cylinders which haven't been ignited.

Car will not start due to faulty electrical components.

In addition to the traditional systems such as starter motors and simple systems like radios, the electrical systems of modern cars now need to cope with many more components. Such things as modern safety systems & controls and a range of electronic devices such as navigation systems and various entertainment devices all rely on your auto electrical system to function.

Auto Electrical Services from Blackwood Dyno Tune & Service include testing, servicing, refitting and repairing a whole range of electrical components fitted to different types of vehicles including:

When you have to get back on the road or back on with your day, you need a mechanic in Blackwood you can trust. A vehicle's ignition system is designed to ignite a fuel-air mixture.

Our customers visit us for a range of reasons, from an alternator which will not catch to a car which will not start. There are several things which can go wrong with the ignition system such as:

Wear and Tear: The battery, spark plugs, distributor cap and wires will not last forever. Replacement of these items at regular intervals prevents larger ignition issues.

Weak Ignition: When spark plugs need to be replaced it is usually not all of them at once. A misfire in one or more sparkplugs will cause a weak start-up of the car and is an indication that a service may be needed soon.

Battery Issues: A battery can wear out or its terminals become corroded. We have the equipment to clean and test batteries or can replace them as needed.

Coil Wire is Frayed: When the charge is not carried to the spark plugs, the ignition fails to catch and the coil wire must be replaced.

Automotive Servicing, Tuning and Repairs in Blackwood, South Australia

Diesel vehicles are great cars – renowned for their torque (towing capacity) and fuel efficiency. However, they can occasionally present challenges that require expert attention. It’s important to find a mechanic who understands diesel engines and their intricate design. 

At Blackwood Dyno Tune & Service, we are fully equipped and certified to work on, diagnose and repair your diesel vehicles. All our technicians are fully qualified diesel mechanics, certified through Repco’s Auto-Tech training program.

With our diagnostic scan tools and comprehensive knowledge, just know that your diesel vehicles are in the best possible care at Blackwood Dyno Tune & Service. 

Did you know that it is not recommended to travel short distances daily with your diesel engine? The engine does not get warm enough for regeneration to take place, resulting in the diesel particulate filter becoming very quickly full of soot particles. 

A diesel engine draws in large amounts of air to operate efficiently. Over time, carbon deposits build up on the inner walls of the induction system. This carbon (black soot, similar to what you would find in a chimney) restricts air flow, affecting performance, and if left untreated, carbon build up can decrease performance and economy. 

These are 5 parts of your Diesel engine that you should know about:

ECU (Engine Control Unit): This is essentially the vehicle's brain. The diagnostic scan assesses the ECU for any error codes, misconfigurations, or software issues that might affect engine performance.

Fuel Injection System: Diagnostics check the timing, spray pattern, and operation of the injectors to ensure the fuel is being delivered to the engine properly, which is critical for maintaining fuel efficiency and engine performance.

Turbocharger System: Scans the turbocharger for issues related to its operation, including reduced boost pressure and leaks that could result in decreased engine power and increased fuel consumption.

Exhaust System (including DPF): Checks for blockages or malfunctions within the Diesel Particulate Filter (DPF) and the entire exhaust system, which can lead to increased emissions and reduced engine performance.

Cooling System: Evaluates the operation of the radiator, water pump, and thermostat to prevent overheating, which is vital for preventing engine damage.

Some of the most common issues faced by diesel engines include: 

What other issues can occur with Diesel Engines? 

Poor Fuel Quality: Contaminated or low-quality diesel fuel can lead to clogged fuel injectors and reduced engine performance.

Turbocharger Failure: Turbochargers can fail due to wear and tear, improper maintenance, or foreign objects damaging the turbine, leading to a significant loss of power.

Overheating: Diesel engines can overheat due to cooling system malfunctions, such as a faulty thermostat or a clogged radiator, potentially causing severe engine damage.

Starting Issues: Cold weather or faulty glow plugs can lead to difficulties in starting the engine, as diesel engines rely on heat for the ignition.

EGR (Exhaust Gas Recirculation) Valve Failure: The EGR valve helps lower the vehicle's emissions; however, if it becomes clogged or malfunctions, it can cause engine performance issues and increased emissions.

At Blackwood Dyno Tune & Service, we work towards extending the life of your diesel vehicle, by using our comprehensive knowledge and specialised scan tools, to take a deeper look at the problems occurring. The scan covers crucial components, such as the engine control unit (ECU; essentially the vehicle’s “brain”), fuel injection system, exhaust system, and more, providing a comprehensive health check that is essential for maintaining the vehicles performance. We can save you money by finding the problem early on!

Just know that when you bring your diesel vehicle into us at Blackwood Dyno Tune & Service, it is in the best care. We will communicate with you throughout the entire process and answer any questions you may have!

Premier Diesel Engine Diagnostics and Repair in Blackwood

 A customer with a Ford Ranger called with a lack of power and engine light on issue. In this instance there were 3 different reasons for the power loss and engine light to be on. When diagnosing faults, never assume it is the first one you find. 

The front bumper and grill were removed, exposing the old leaking intercooler.

This image shows the damaged Turbo Charger intake wheel, which had to be replaced due to irreparable damage as described above.

Above you can see specks of aluminium from the turbo stuck to the carbon inside the intake manifold. We also highly recommend for turbo diesel vehicles, an annual intake throttle carbon clean and then a fitment of an oil catch can to stop the heavy carbon build up in the inlet manifold. 

Finally, the new replacement intercooler has now been fitted after repairing the turbo charger and cleaning the intake manifold. Most turbo vehicles have the intercooler fitted in front of the radiator.

When diagnosing vehicle faults, we never assume it is the first one we find.

Don't buy a Lemon - Pre Purchase Vehicle Inspections in Blackwood

The customer brought his Nissan Urvan mobile home to us, requiring the removal of the LPG gas tank from the dual fuel system as they were having running problems with the van not running on LPG.

It was a wise a decision because the cost to repair the LPG system outweighed the gains achieved using a cheaper fuel. Plus the vehicle would be lighter and be more fuel efficient running on petrol due to the restrictions on air intake when LPG is installed. They chose Blackwood Dyno Tune & Service as we’re fully licensed to fit, service and remove LPG systems.

To remove the LPG tank from underneath the motor home, it was raised on the hoist. Some tanks are installed inside the cabin of the car or more usually in the boot area, so when you remove the LPG tank it increases the luggage/storage space to a factory configuration. The LPG tank does not have to be empty to remove it from the vehicle. 

Here’s the LPG 100 litre tank that was removed from the Nissan Urvan. During the removal procedure we also remove the LPG fuel lines, associated wiring, gauges and electrical switches in the cabin.

This shows the LPG Converter, associated wiring, gauges, electrical switches, feed and supply lines that were also removed from vehicle. Once the system has been removed, we then adjust the tune for the vehicle to run correctly and efficiently on petrol, as this would have been changed when the LPG system was originally fitted to the vehicle.
