Diagnostics & Coding

As cars get more advanced, it can be difficult to know if there is an issue.

ECUs and sensors on our cars help to make our lives easier than ever before, but they need extra care and attention to make sure that your vehicle is running safely and at its best! If you’ve noticed strange noises or vibrations when you’re driving, or you have an engine warning light, it’s important to get the problem identified and sorted sooner rather than later. Fortunately, that’s exactly where GLM Automotive can help.

We offer a range of diagnostics and coding services in Surrey, Woking, Guildford, Redhill and the surrounding areas. We give our customers peace of mind that their car’s computers are working exactly as they should and that your vehicle is fully optimised.

What Does a Car Diagnostic Check Do?

During a diagnostic check, a skilled mechanic connects your vehicle to a specialised code reader to thoroughly assess its condition. This process effectively identifies issues that might be hard to pick up manually, and that you might not be able to identify yourself when driving.

The diagnostic check focuses on examining crucial components, including the car’s electronic control units (ECUs), responsible for managing various aspects of the vehicle’s performance, such as engine operation.

It also checks the healthy running of a range of other components, including:

Airflow and coolant
Braking system
Electrical components such as central door locking
Emissions and exhaust sensors
Fuel injectors
Ignition coils
Throttle setting
Transmission (if the transmission is electronically controlled)

What is Coding?

Car coding is a way of modifying the vehicle software so that it is different to the way it left the factory. The most common reason for coding is to adapt to local vehicle regulations.

However, this doesn’t mean you can do whatever you want with your car’s internal computer! In every vehicle, there are existing parameters already in place to prevent any illegal or unsafe modifications, and all coding changes are made within these parameters.

This is why it’s so important to come to an expert for car coding in Surrey – our team can adapt and customise your vehicle’s code in a way that keeps you safe and makes sure your car is still legally compliant. To find out how we can help, get in touch!

Mercedes Coding and SCN Coding

SCN coding stands for Software Calibration Number coding and is a specialist process unique to Mercedes-Benz vehicles. Only authorised Mercedes-Benz technicians can use these features to help protect your vehicle and carry out repairs.

Modern cars can be quite complex, which means it’s not unusual to encounter issues with various control units or notice small changes in your vehicle’s performance. In some cases, an issue that you may initially think is mechanical or electrical can turn out to be a problem solved by SCN coding.

Even if there are no electrical problems, we can perform software updates to improve your vehicle’s performance. So, whether you’re experiencing a slightly rough gear change or that persistent warning light on your dashboard, our updates will help your car run smoothly and efficiently.
