2013 Mercedes-Benz C250
The Value of Real Matrix Wand Data:
This 2013 Mercedes-Benz C250 was in the shop after having been repaired elsewhere. After repair, the customer complained multiple times that the vehicle wasn't handling properly, despite the shop having a printout from the alignment shop showing that everything was in spec. The structural tech reviewed the original damage appraisal and based on personal experience, diagnosed damage to the left front strut tower. However, the estimator disagreed with the diagnosis and asked the shop's blueprint technician to analyze the vehicle using data obtained from the Matrix Wand.
Using the new Matrix Active Map 3-D™ feature, the blueprinting technician was able to use measured data points and diagnose the left front strut tower was not damaged in any way. Further there was no movement on the front structure of any kind. Once this confirmed analysis was generated, everyone involved knew the problem was located somewhere else and was not located in the front structure of the vehicle.
In slightly less than 10 minutes, the front upper structure of the vehicle was eliminated as the cause of the vehicle handling problem. Further analysis revealed a damaged left lower control arm and cradle misalignment. (possibly by the alignment shop in an attempt to compensate for the bent control arm).
