Where is the sunroof drain hole located on the Mercedes-Benz C-Class 180?
2 Answers
The Mercedes-Benz C-Class 180 has one drain hole at each of the four corners of the sunroof, which can be seen when the sunroof is opened. Below is some relevant information about the Mercedes-Benz C-Class: 1. Exterior: The exterior styling changes of the new Mercedes-Benz C180 model are not significant, mainly involving the front bumper, LED daytime running lights, and new wheel rims. Inside the vehicle, the most notable change is the addition of chrome trim to the glove box handle. 2. Powertrain: Although the new Mercedes-Benz C180 model is equipped with only a 1.6-liter engine, its maximum power and torque reach up to 115Kw/5200 and 230N·m/3000-4500, respectively, which are 15Kw and 50N·m higher than those of the BMW 318i with a 2.0-liter engine.
I used to drive a Mercedes-Benz C180, and I've personally experienced the issue with sunroof drainage holes several times. Typically, these drainage holes are located in the four corners: two at the front near the upper edge of the windshield in the A-pillar area, and two at the rear of the roof near the C-pillar or trunk edge. Last time I cleaned them, I felt around the gaps in the sunroof frame from the driver's seat and traced them to those small holes. The drainage holes are crucial components to prevent rainwater from accumulating in the sunroof channel and leaking into the car. Once, I didn't clean them in time, and debris clogged the holes, resulting in water seeping into the cabin and wetting the seats. Since then, I've been using a soft hose to flush and clean them every six months to avoid clogging issues. It's quite convenient to do it yourself without professional tools, but you need to be careful not to damage the wiring. Overall, finding these small holes is simple; just observe around the sunroof regularly, and you'll spot them.
