Tumping Noise back right side

Hi, I'm Bogi, one of the auto experts on RepairPal's Car Genius team! On your 2017 Mercedes GLA250 a thumping noise that occurs specifically at low speeds and when coming to a stop is a pretty telling symptom. The most common culprits for this type of noise are worn or failing CV axles, which tend to make a clunking or thumping sound at low speeds and under light load conditions. Worn sway bar end links or bushings are another very common cause of this type of noise, as they can knock and thump when the suspension moves slowly during deceleration. A warped or unevenly worn brake rotor is also worth considering, as it can produce a thumping sensation that is most noticeable at lower speeds. There even could be something with your wheel or tire causing the noise, and it is just more audible at low speeds. I’d recommend having a qualified shop do a proper inspection sooner rather than later, since some of the possible causes are safety related. A shop with European vehicle experience would be ideal for a Mercedes.
