Thank you for the information.

I acquired my first MB C220D W204 from the original owner and am very satisfied. The service history is entirely digital; other from visiting a dealer, is there anybody who can assist? Identification WDD2040022A540242.

It is accurate that it has not been driven much, accumulating barely 10,000 km over four years. The garage personnel are generally reliable, yet end customers like us inevitably have some skepticism over their judgment. Reading about various concerns on the internet may indeed be intimidating. I am willing to attempt shifting the tires and wheels to assess the outcome.

Greetings, everyone. Recently, I traveled from Nottingham to Wales for business. As my car's air conditioning was inoperative, I intermittently opened the window to get fresh air. Operated the vehicle at a velocity between 70 and 90. Upon closing the windows, I noticed a buzzing noise that intensified with speed, which I suspected may be attributed to the wheel bearings. The mechanic inspected the vehicle and confirmed that the bearings are functioning properly. However, the rear tires are producing noise, despite having acceptable tread depth, which is attributed to their inferior quality. This pertains to the 2007 W211 E220 model, which has accumulated 180,000 kilometers. Front tires - Pirelli - Cinturato (exceeding 5 years in age, however retaining substantial tread depth) Replace both rear tires - Dynamo (installed in mid-2021, although the vehicle has only been driven 10,000 miles since) - the tread is also highly effective in this regard I detected tire noise according to the road type, but I disregarded it since it was not very bothersome. Recently, the rear shock absorbers were replaced (non-2024), and during a lengthy work-related trip, I noticed a significant amount of humming sounds. I conducted an online search for similar sounds. The rear tires are expected to last at least 40,000 miles; however, mine had worn out after just 10,000 km. The rear shock absorber has also been modified lately. What are your opinions on this noise? Additionally, how can I accurately ascertain which tires are producing the noise? Thank you for your assistance.
