Case Study | CTEK Revolutionize Operations at Mercedes Waterloo, Belgium

Mercedes Waterloo, part of the Saga Mercedes dealership in Waterloo, Belgium, boasts an impressive track record in sales and after-sales service. They cater to a diverse range of vehicles, including electric, hybrid, and thermal cars. Their commitment to exceptional service recently earned them the prestigious award for the best Mercedes dealership in after-sales service in Belgium. 

Mercedes Waterloo prides itself on providing top-tier automotive service. With a team of 10 highly skilled technicians handling approximately 25 vehicles each day, their workshop undertakes various tasks, from mechanical repairs to diagnostics and electrical work. Ensuring customer satisfaction and timely service delivery is their primary goal. 

One significant challenge they faced was during the process of updating specific Engine Control Units (ECUs). This intricate task demanded a constant voltage supply, sometimes spanning several hours. Their existing chargers were found lacking, occasionally causing hiccups and glitches when flashing the ECUs. 

Recognizing the need for a robust and dependable charging solution, Mercedes Waterloo turned to CTEK and their PRO120 battery support unit. The results were transformative. 

Jéremi, the Workshop Manager at Saga Mercedes Waterloo, elaborated on their experience with the CTEK PRO120: "We have a team of 10 technicians, and we take care of more or less 25 vehicles per day, covering all types of mechanical repairs, maintenance, diagnosis, and electrical work. Our goal is that the customer is satisfied and that they get their car back on time." 

He continued, "During the process of updating certain ECUs, it is necessary to ensure a constant voltage, sometimes for three, four hours, or even more. We need a product that is powerful enough; our old chargers weren't up to the task and caused occasional issues when flashing the ECUs. With the CTEK PRO120, we never had any more worries. It is fast and efficient. We first tested a CTEK PRO120 and we were pleasantly surprised, so we ordered more!" 

Jéremi emphasized the vital role of the CTEK charger: "We run diagnostic programs on most of the vehicles that come into the workshop. For that, we need to ensure a constant power supply. The CTEK charger has really become an indispensable tool, more important than a 10mm wrench! When we know we have to update an engine ECU, the first thing we do is to plug the battery support unit into the vehicle." 

He concluded, "So, simply two clamps, a positive and a ground. We can directly see the battery voltage on the screen of the charger, which indicates to us that it is in order. Then, we connect the computer, and we can start the updating process. The computer will also show us the battery voltage in real time, which must be quite high, sometimes for an hour or two, sometimes more." 

In summary, the CTEK PRO120 charger has become an indispensable asset for Mercedes Waterloo. It has empowered their team to carry out critical tasks such as ECU updates with efficiency and reliability, ensuring that they meet their primary goal of providing exceptional service to their customers. The collaboration with CTEK has resulted in streamlined operations and enhanced customer satisfaction at Mercedes Waterloo.
