Automotive Mechanics & Mechatronics

D.T. Dobie Training Center

This training course covered Automotive Technology,  Automotive Mechatronics, Automotive Electrics, Metal work and repair instructions on Mercedes passenger car and Trucks. This course prepares one for the diverse Automotive Industry.


Truck Spec'ing

It is vital to provide a customer with a truck suitable for his operations. This way the customer does not incur unnecessary expenses especially increased fuel consumption. I do this by identifying the ideal engine, transmission and drive axle ratio for the customer before ordering the truck. This is part of Key Account Management.

Truck Air Production Systems Troubleshooting & Repair.

Trucks make use of compressed air for various tasks including brakes, gear control and so on. It is important to be familiar with the system so as to perform accurate diagnosis and repairs.

Key Account Management.

This involves providing technical solutions to one's fleet customers personally or involving the manufacturer via online dealer portals such as the Xentry TIPS for Mercedes trucks. It's always important to point out the benefits of Genuine parts and Service contracts.

Roadside Recovery & Repairs.

Accurate and quick diagnosis and repair in the field for broken down trucks is key to minimizing downtime and saving the customer money.

Truck & Trailer Wheel Alignment

This involves performing accurate wheel alignment for truck and trailer with a by-the-book approach. This is important to the customer as misaligned truck and trailer axles increase the operating costs of the customer in terms of premature tyre wear as well as increased fuel consumption.

Unit Troubleshooting & Overhaul.

This is the fault finding and repair of major assemblies in a truck such as engines, transmissions and drive axles. It's vital this is done professionally so as to avoid future failures resulting in increased costs to the customer as well as downtime.

Engine Testing

It is necessary in many cases to test an Engine for lack of power, misfiring, oil consumption and so on. It is necessary that engine testing is done accurately so as to save the customer from unnecessary expenses occasioned by misdiagnosis.

Electrical & Electronic Systems Retrofitting.

Adding systems that are not part of the vehicle ex factory. This is a particularly useful skill as one has to perform the retrofit accurately and by the book so as not to damage the existing systems of the vehicle.

Computerised Auto Diagnostics

With the possession of this skill I am able to perform accurate diagnosis and repair on Truck Electronic systems quicker with the Mercedes Xentry Star Diagnosis so as to minimize downtime which I key to my customers. These systems include but are not limited to Engine management systems such as the PLN and Common Rail, Electronic braking systems such as WABCO EBS, Transmission Control systems such as the Mercedes Powershift and Telligent gearshift systems and so on.
