Tune Up & Diagnostics

Tune-Up & Warnings Lights Diagnostics

The Engine Tune-up is an essential part of your engine running. Regular Engine Tune-up maintenance is an important formula for fuel-efficient and saving. Infrequent tune-ups can increase fuel consumption up to 50% percent leading to poor fuel mileage, rough running and difficult starting.

For better performance and smooth starting, it is essential that your engine is maintained regularly. The tune-up is a series of maintenance steps aimed at restoring engine optimal operation including, among other things, replacing air filter, spark plugs, cleaning the injectors, hrottle body and fuel filter replacement.

- Engine Fault Warning Light (Check Engine).
- Difficult Engine Starting
- Unstable Engine Idling.
- Fuel Consumption.
- Unpleasant Smell From Exhaust.

Most manufacturers recommend an engine tune-up check every 36 months or 60 thousand kilometers (38,000 miles).

If the message (DRIVE TO WORKSHOP) appears on your dashboard. It is important not to ignore this message, this indicates that there is a potential mechanical, electronic or pneumatic problem with the suspension of your vehicle.


Some vehicles are equipped with driver assistance systems that use proximity sensors to monitor nearby vehicles and help the driver maintain a safe distance. These systems can also be used to alert the driver in the event of an unsafe lane change or risk of collision.

It is important not to ignore warning lights related to safety systems can compromise your vehicle's safety features and increase the risk of an accident.



When the "Check Engine" or "Service Engine Soon" light illuminates on your vehicle's dashboard, it indicates that there is a problem with the management system of the motor. Here are some common reasons why the check engine light may come ON:

Defective spark plug or ignition coil. This can lead to poor fuel combustion in the combustion chambers.

This may include problems with the fuel injection, fuel injectors, or fuel system.

This can include faults in the engine management system, such as faulty sensors or electrical actuators.

This may include a problem with the exhaust system, catalyst, or oxygen sensors.

Some cars may also turn on the check engine light for transmission-related problems, such as high transmission temperatures or transmission-specific malfunction codes.

If the message (DRIVE TO WORKSHOP) appears on your dashboard. It is important not to ignore this message, this indicates that there is a potential mechanical or electronic problem with your vehicle's transmission.


The brake warning light is a light on the dashboard that illuminates to indicate a potential problem with your vehicle's brake system. When the brake warning light comes on, it is important not to ignore this signal, it can mean several things, including:

A low brake fluid level may indicate a leak in the brake system or simply normal wear and tear of the brake fluid over time.

If the brake pads are worn, the brake light may come on to alert you that it is time to replace them. It can also indicate excessive wear of the brake rotors.

The brake light may also illuminate if there is a problem with other components of the brake system, such as the ABS sensors, brake calipers, or brake lines.


When the anti-lock brake (ABS) light illuminates on your car's dashboard, it usually signals a problem with the anti-lock brake system.


If the Traction and Stability Control light stays on continuously or flashes while you are driving: this may indicate a malfunction in one of the control systems (ESC) or (TCS).


The airbag light may illuminate due to a problem detected with one of your vehicle's airbags. This could be caused by a faulty sensor, loose connector, electrical problem, or a fault in the airbag deployment system.
