HOW IT WORKS?
We will start with a consultation to understand the issues you are experiencing, before our Modern Classic team will follow the diagnosis process for your particular car and the issue you are experiencing. Our team possess industry leading technology to diagnose issues with your R129, but limitations are presented by the number of faults that the ECUs present.
Examples of how we diagnose an issue:
EARLY R129 (1990-1993)
Poor running: This era of V8 models retained the same injection system as the late R107s. The KE fuel Injection system can be compromised by corroded lines, issues with the coils or HT leads, causing starting and running issues. Due to the simpler nature of this system, it is easier to locate and identify such an issue by checking these components.
Soft top issues: Earlier R129 models have basic ECUs that can be read using a ‘flash code reader’. This is a system whereby the number of flashes indicates a potential, leading our team in the right direction. This is a directional support and finding the definitive issue comes down to individual testing of your soft top’s electrical components.
LATE R129 (1997/98 ONWARDS):
Poor Running: Six-cylinder models from 1996 onwards feature MAF sensors, which are responsible for ensuring the correct flow of air into your engine. Over time, contamination will occur and your engine may run rich and blow smoke or run lean and hesitate under acceleration. Our team can instantly identify these issues simply by driving and inspecting your car. No technology necessary.
Soft top issues: With developments in technology during the R129’s life, new ECUs were incorporated to allow more advanced diagnostics. We possess the STAR computer equipment purpose built to diagnose electrical faults on the R129. This allows our team to use live data to quickly identify your soft top system’s faults.
This is just a snapshot of the varying approach our team takes to the R129 SL. Other diagnostic areas that our tools allow include issues with traction control, ABS and the CAN-BUS electrical system.
