Diesel engine vehicles are a favourite for Australian cross-country motorists as they are sturdy enough to withstand driving on rough terrain without succumbing to breakdowns. Nonetheless, the durability of the engine is only as good as the frequency of its servicing. If you neglect to take your car to the auto shop as regularly as it needs because of trying to keep your expenses down, you will find the repair costs you are accumulating will burn a hole through your wallet. Not to mention that the terrain the vehicle is exposed to and the mileage would dictate how frequent the servicing needs to be carried out. The following are key signs that your car requires diesel tuning.
The vehicle is hard starting
If you are finding that your engine is taking longer to start or if you are experiencing general difficulty with starting the car, it could be a symptom of decreased compression or a problem with fuel delivery. Unfortunately, since some diesel engines tend to develop issues with delayed cranking over time, some motorists may ignore this symptom assuming that it will go away on its own. In reality, the root of the problem could become aggravated and cause permanent damage to your diesel engine. It would be advisable to seek out diesel tuning services to ensure your engine does not become compromised.
The exhaust is emitting too much smoke
A common visual some people have about diesel engine vehicles is cars that consistently blow out dark plumes of smoke. This visual is a misconception, as diesel fuel has become more efficient over the years, translating into minimal smoke emissions. Therefore, if your diesel vehicle starts to emit large volumes of smoke, you should take the time to determine what could be causing this. One of the main reasons why your exhaust would be emitting excessive smoke is if the vehicle's fuel injector has developed a malfunction. However, your exhaust may emit too much smoke if the injector pump is damaged or if the air filters have acquired blockages.
The engine is making knocking noises
Engine knocking is a telltale symptom of an old diesel engine. However, if your car is new, your engine should not be making any knocking noises. If the knocking starts of spontaneously, it could be a sign that your vehicle's fuel has become contaminated. It should also be noted that diesel injectors that are malfunctioning would directly affect the compression balance in your engine, leading to knocking noises. Diesel tuning would be essential to prevent further damage.
