Suzuki Wagon R Rough Idle Points to Mount Issues

My 2019 Suzuki Wagon R has developed rough idling and stored an error code. The vibration issues have gotten worse over the past weeks, especially when the car is stationary. Im suspecting a defective engine mount or transmission mount might be causing these problems. Has anyone dealt with similar symptoms on their Wagon R? Looking for feedback from those whove had motor mount replacements done, what was the repair process like and did it solve the issue? Also interested in knowing if there were any specific mounting bracket problems common to this model. Thanks in advance for sharing your repair experiences.

Having dealt with similar vibration issues on my 2017 Suzuki Swift, I can share some relevant experience. As someone with moderate DIY car maintenance experience, I initially thought it was a worn engine mount causing the rough idle. After investigating, my mechanic found the root cause was actually a loose connection in the wiring harness near the motor mount area. The cable connection to a sensor had deteriorated, triggering error codes and causing inconsistent engine performance. The mounting bracket and engine mounts themselves were actually in good condition. The repair involved: Diagnostic scan, Visual inspection of mount wear, Testing all sensor connections, Replacing the damaged wiring connector, Final testing to confirm fix Total cost was 95€ for parts and labor. The vibration issues completely resolved after the repair. For your Wagon R, could you share: Current mileage, Exact error code showing, Whether vibration changes with engine temperature, If the problem is worse in specific driving conditions This information would help determine if your issue matches what I experienced or points to actual mount wear instead.

I recently had this issue checked at 19081 KM during my service. After checking my engine mount and mounting brackets, the mechanic found clear signs of mount failure on the passenger side. The mount had deteriorated faster than normal, creating excessive engine movement at idle. Running a diagnostic scan revealed P0135 alongside the mount wear issue. When they replaced both the faulty engine mount and reinforced the mounting bracket, the vibration stopped completely. The service tech mentioned this particular mount failure pattern is something they see occasionally on similar models. Would you mind sharing which error code your scan showed? This could help confirm if your symptoms match what I experienced.

Thanks for following up about the error codes. In my case with the Swift, the initial scan actually showed error code P0135 as well, which is interesting since we had different root causes despite similar symptoms. The failed mount in your case explains the severe vibration issues. While my problem was electrical, the symptoms can be quite similar, both a defective engine mount and sensor issues can cause rough idling. The transmission mount was also inspected during my repair but was found to be solid. My mileage was around 21000 KM when the issue appeared. After fixing the wiring near the motor mount area, we did a follow-up scan that showed all clear. The fact that your mounting bracket also needed reinforcement suggests your issue was more structural than mine. The repair cost breakdown in my case was different since it focused on electrical work rather than mount replacement: Diagnostic: 35€, Wiring repair: 60€ Since both our cars had the same error code but different underlying problems, this really highlights why proper diagnosis is crucial when dealing with vibration issues and rough idling.

Thanks for the detailed comparison of our repair experiences. You're right about mount wear being the culprit in my case, as confirmed by the repair outcome. The P0135 code showing up in both situations is quite interesting, even though we had different root causes. My total repair costs came to: Diagnostic: 40€, Engine mount: 185€, Mounting bracket reinforcement: 95€, Labor: 160€ The vibration issues completely disappeared after fixing the defective engine mount. Im glad I had it checked when I did, as the mechanic mentioned continued mount wear could have led to more serious engine problems over time. Thanks for sharing those details about your wiring issue, its helpful to know that similar symptoms can have such different causes. Been running smooth for about 2000 KM now since the repair, so looks like we both got our problems sorted, even though they required different solutions.
