The Mercedes W140 S-Class V8 engine had developed an intermittent misfiring fault. The misfiring could be observed during idle speed when the engine was warm – however it was not a serious issue. Within a month it became apparent that as the engine coolant temperature reached 60 °C, the ‘intermittent’ fault became permanent. At this stage the car was still drivable, but had significantly less performance than expected and higher fuel consumption than normal.

Our Automotive forum has now been launched! The forum is a place for existing customers, new customers, and even those who simply need help to communicate, all in one place. It's a place for you to announce your findings, for hints and tips, for information on using the latest features, and perhaps hearing of features you may not have realised existed. One area in particular we hope you will find interesting and want to contribute to is our case study section. Here, you can post your findings for others to learn from, and spread the knowledge of faults for all makes and models of the cars you may work on. This information may be invaluable to others on the forum, and you may even get a thank you!
To help launch this new forum, and the case study section in particular, we are running a small competition. If you feel you have something to offer the community, and can present it inline with the guidelines listed, you could be in with a chance of winning a first prize of a WPS500X pressure sensor kit, or a one of two runner up prizes of a set of COP probes!
