Mercedes-Benz Sprinter Sliding Door Problems - How To Troubleshoot and Fix

Sliding doors contribute greatly to comfort level when stepping in and out of your Mercedes-Benz Sprinter. They help provide better clearance than standard doors and open and close on their own, which is great for accommodating large families and loading and off-loading cargo.

Let's discuss common problems with the sliding door of the Mercedes-Benz Sprinter. Keep reading to learn more about how sliding doors work, symptoms of a defective sliding door, and steps you can take to troubleshoot, diagnose, and go about fixing those common issues.

How Do Mercedes-Benz Sprinter Sliding Doors Work?

Sliding doors use a complex system, comprised of a motor, chain drive, and gears to open and close a door, automatically setting into a locking position. They are designed to remain in the locking position no matter how hard or soft you drive.

Common Mercedes-Benz Sprinter Sliding Door Issues?

Door Cannot Open and Close

Problem - Debris, rocks, dirt, and loose particles that sit on or beside your cable track can cause your cable track to break, making it difficult to open or close your sliding door. 

Solution - Replacing a worn-out cable track involves removing the door trim using am assembly wedge, stripping off the door handle, and disconnecting entrance lights before removing the entrance trim. These steps expose your Mercedes-Benz Sprinter's cable track. From there, its a relatively straightforward process of vacuuming to remove all dirt and contaminants.

Ratting Sound

Poor Lubrication

Problem - If you experience a rattling and vibration sound while opening and closing your sliding door while driving, it may be a sign of poor lubrication. A joint, pivot, or latch could become excessively dry, grinding against your chassis.

Solution - Fixing the rattling sound is straightforward. Access the lower track that your sliding door rides on, wipe it clean of debris using a dry rag, and use white lithium grease spray and wipe it against the track. Be sure to apply a generous coating. Use a thin spray tube to reach deep into crevices where fingers or brushes cannot reach. Do not forget to address the door latch or wheel riding on the track. Pay attention to any parts with pivot points, which are especially prone to rattling and vibrating with a lack of lubrication.

Bent Post

Problem - Another potential cause of a rattling Mercedes-Benz Sprinter sliding door is a bent post. A bent post causes the door to not sit flush with your door lines, which may cause it to rattle and vibrate with high speeds. 

Solution - Simply use a 15mm socket to move the post several millimeters closer to the vehicle. When closing the door, your door should line up perfectly and eliminate noise. This process should take no more than five minutes.

Fixing Your Mercedes-Benz Sprinter Sliding Door Problems

Fixing sliding doors requires a moderate understanding of pivot points and other mechanisms that open and close. The broken door should not impact overall drivability unless your sliding door is locked in the open position. At most, you will experience mild to heavy rattling and vibration, especially when in motion.

Note, a defective sliding door may not necessarily impact drivability as long as you can open and close it with force. A sliding door that remains open can cause plenty of problems, including break-ins or injury while driving.

Unlike routine oil changes or wheel rotations, the sliding door does not require regularly scheduled maintenance, subject to unexpected wear and tear regardless of mileage or driving conditions.
