Happy Mashujaa day..who is your shujaa??

Why modern gearboxes can behave differently when cold.Some automatic and dual clutch transmissions behave differently when cold because fluid viscosity, hydraulic pressure and clutch control strategies change with temperature. A slight difference in shift behaviour may be normal for a particular model, but harsh engagement, slipping, delayed selection or repeated warning messages should not be ignored. The technician needs to consider the gearbox design, fluid specification, temperature, fault codes and service history before reaching a conclusion. Simply changing the fluid or condemning the gearbox without proper assessment may not solve the problem. What matters is understanding why the behaviour is occurring.

Why repeated short trips can affect modern diesel vehicles. Many modern diesel vehicles use a diesel particulate filter to capture soot from the exhaust. Under suitable conditions, the vehicle performs regeneration, a process that raises exhaust temperatures to burn off accumulated soot. Repeated short journeys may prevent some vehicles from completing regeneration consistently, depending on driving conditions and the manufacturer’s strategy. Over time, this can contribute to filter restriction or warning messages. If a warning appears repeatedly, the underlying cause should be investigated rather than forcing regeneration without checking the system. Sensors, engine performance and the condition of the filter all matter. For all your diesel engine repairs visit us along Magadi rd or dial a booking via 0708455455.

A vehicle can look attractive after bodywork while concealing evidence of previous accident damage. Uneven panel gaps, inconsistent paint thickness, poor weld quality, overspray and incorrectly fitted components may indicate earlier repairs. However, none of these signs alone proves that a vehicle has suffered serious structural damage. A proper inspection may also involve checking the chassis, structural measuring points, airbags and relevant electronic systems. When buying a used vehicle, the important thing is to establish the extent and quality of any previous repairs, especially where safety related components may have been affected.

Why a turbocharger failure is not always just a turbo problem. By this I mean, when a turbocharger fails, replacing it without investigating the original cause can lead to another expensive repair. Turbochargers depend on correct lubrication, clean oil supply, suitable operating conditions and proper boost control. Oil starvation, restricted oil passages, excessive crankcase pressure, intake leaks or problems with the engine itself may contribute to failure. The turbocharger should therefore be inspected alongside the systems that support it. At Precision Automotive, the important question is not simply which component has failed, but what caused it to fail in the first place.

Why a weak battery can cause multiple warning lights. A weak or failing 12-volt battery can sometimes cause several warning lights to appear at once. Modern vehicles depend on stable electrical voltage, and low voltage during starting can interfere with the operation of electronic modules or trigger communication errors. However, not every warning light is caused by the battery. The correct approach is to test battery condition, charging performance and relevant fault codes before replacing parts. Clearing the warnings without identifying the cause may only provide temporary relief if the underlying electrical problem remains.

We are skimming these brake discs to restore a smooth, even braking surface and improve contact between the discs and brake pads. This helps address issues such as brake pedal pulsation, steering vibration during braking, and uneven pad wear, provided the discs are still within the manufacturer’s minimum thickness specifications. At Precision Automotive, we believe proper brake service starts with inspection, not guesswork. If a disc is too thin, cracked, or damaged beyond acceptable limits, replacement is the safer option. Remember, your braking system is too important to compromise. Muringa Rd, Kilimani | Magadi Rd, Karen. 0708455455 / 0712455455

Under the hood of this Range Rover is a fuel burning auxiliary heater as they call it, Webasto/Eberspächer, a specialized winter system designed to pre heat the engine's coolant with a mix of water and antifreeze, before or during cold starts. Utilizing fuel directly from the vehicle's tank, the unit ignites inside its burner assembly. From the picture you can see its dedicated flexible metallic exhaust pipe routed below. Its work is to warm the circulating coolant. This process delivers instant cabin heat, rapidly defrosts the windshield, and reduces harsh engine wear from cold winter starts, making it a critical comfort and reliability feature in colder climates.

Cars are becoming computers on wheels. What does this mean? Vehicle technology has changed considerably over the years. Modern cars rely on electronic control units to manage everything from engine performance and transmission shifts to climate control and safety systems. Some manufacturers also provide software updates that improve functionality or address specific faults. This means a technician may need to investigate software, communication networks and mechanical components before identifying the real cause of a problem. Mechanical knowledge remains essential, but understanding vehicle electronics is becoming equally important as automotive technology advances.

Modern vehicles increasingly use cameras and radar sensors to support features such as automatic emergency braking, lane assistance and adaptive cruise control. Some of these sensors are mounted behind the windscreen, grille or bumper. When these components are replaced or disturbed, the sensors may require recalibration according to the manufacturer’s procedure. A vehicle can look perfectly repaired while a driver-assistance system is no longer operating accurately. This is why certain body repairs need to be followed by electronic checks and calibration, not just painting and panel alignment. Dial 0708455455 for bookings.

Hybrid vehicles combine a conventional engine with an electric motor, a battery and several electronic control systems. These components must work together efficiently, and a problem in one system can affect the performance of the others. For example, a hybrid battery fault may cause the petrol engine to run more frequently, affecting fuel economy. Proper diagnosis involves checking battery health, cooling, charging performance and the interaction between the different systems. Owning a hybrid can offer real benefits, but understanding its condition is just as important as understanding its fuel consumption. So would you still go hybrid?? Anyway we fix your hybrid as much as we service them. Dial a booking on 0708455455.

A car can pass a diagnostic scan and still have a serious mechanical problem because a scan tool reads electronic data and fault codes; it does not physically inspect the engine, gearbox or other mechanical components. Issues such as worn bearings, low compression, internal engine wear, failing oil pumps or gearbox damage may not trigger a fault code, especially in their early stages. Even when a sensor reports normal values, the actual mechanical condition may be far from healthy. This is why proper diagnosis goes beyond plugging in a scanner. Depending on the symptoms, a mechanic may need to perform compression and leak-down tests, check oil pressure, inspect fluids, carry out physical measurements or conduct a controlled road test. A clean scan report does not automatically mean a healthy car. The scanner is a diagnostic tool, not a final verdict. At Precision Automotive, we look beyond fault codes to identify the root cause of a problem before recommending repairs. Our number is 0708455455. Call us or drop us a WhatsApp message to book.

Not every noise from your car indicates a problem, but knowing the difference between a normal operating sound and a warning sign requires proper diagnosis. Mechanics consider when the noise occurs, where it comes from, its frequency, and whether it changes with engine speed, braking, steering, or acceleration. For example, a light injector ticking sound may be normal in some engines, while deep knocking could indicate internal engine wear. Similarly, squealing brakes may point to worn brake pads, while clunking over bumps could suggest worn suspension components. A mechanic also uses diagnostic tools, physical inspections, and road tests to identify the source rather than relying on sound alone. The key is not to ignore unusual noises or rush into replacing parts without confirming the cause. At @PrecisionAutoKE , we believe proper diagnosis, patience, and technical expertise are essential to identifying problems early and protecting your car from unnecessary damage.

A clean engine bay doesn’t always mean a healthy engine. A good wash can make an engine look almost brand new, but it won’t tell you what is happening internally. An engine can be spotless on the outside while having low oil pressure, worn components, coolant loss, compression issues, electrical faults or even a developing leak. That’s why proper inspection goes beyond appearance. Check the fluids, scan the vehicle, inspect for leaks, listen for abnormal noises, monitor temperatures and, where necessary, carry out proper mechanical tests. Don’t judge the health of an engine by how clean it looks. Diagnose what’s happening underneath.

A single turbo engine uses one turbocharger to compress intake air and increase engine power, while a twin turbo setup uses two turbos, either working together or in sequence. In practice, a single turbo system is generally simpler, easier to maintain and can deliver strong performance, but turbo sizing can affect how quickly it builds boost. Twin turbos can be designed to improve low-RPM response while maintaining strong power at higher RPM, giving the engine a broader and more responsive powerband. However, they also come with more plumbing, components and complexity, so more turbos doesn’t automatically mean a better engine; the setup and calibration matter.
