Instrument Cluster Repair

Your Mercedes Benz instrument cluster contains the most important collection of information you'll ever need while operating your vehicle! Not only are the obvious fuel, speed and tachometer signals important, but engine vitals such as oil pressure, oil level, water coolant level and others, are closely and accurately monitored to keep your vehicle in peak condition.

Thus, if your instrument cluster is starting to show signs of twitchiness, inaccuracy, inoperation or even looks something similar to the one on the right, then it's very likely that you have developed a serious malfunction.

Correcting malfunctions such as sticky gauges, corrupt LCD displays, dead gauges/warning lights is our specialty. Our support includes the early Mercedes classics, such as the R107, W126 and W124.
