To troubleshoot a Mercedes-Benz with a rough shifting condition, remove and disassemble the transmission, as the problem results from an internal component malfunction. Replace the instrument cluster display if it stops working properly. If there's a clicking noise coming from the middle part behind the dash panel, disassemble the center console to replace the broken arm.
Many owners of the Mercedes-Benz E350 and Mercedes-Benz ML350, which operate with a seven-speed automatic transmission, reported on the RepairPal site that their vehicles developed a rough shifting condition. RepairPal technicians explain that Mercedes provided updated parts to solve the issue, allowing vehicle owners to replace the defective parts.
A common problem associated with the Mercedes-Benz SL500 is an active body control system leaking hydraulic fluid from areas such as the seals, struts, hydraulic lines or tandem pump. This issue requires immediate repair by an experienced technician to prevent undercarriage damage due to a very low vehicle ride height.
Door locks tend to cycle quickly when switched on using a door lock switch or keyless remote due to failure in electrical switches. This problem commonly occurs in Mercedes-Benz ML320 and requires replacement of the malfunctioning door latch to resolve the issue. If the Electronic Stability Program or Brake Assist System warning lights lighten, replace the defective switch as the cause of the problem is likely a malfunctioning brake light switch.
