Experiencing issues with your Mercedes-Benz A 220? Our long-term test car recently faced some concerning transmission problems, specifically rough shifts, prompting a visit to the dealership. After putting some miles on the clock, the usually smooth operation of our A 220’s transmission began to deteriorate, leading to noticeable jerky shifts, especially during lower gear changes. This article details our experience diagnosing and addressing these transmission issues, along with insights into the car’s 10,000-mile service.
The initial problem manifested as harsh shifts, particularly noticeable when upshifting from 1st to 2nd gear at around 15-20 mph in both Comfort and Sport driving modes. We replicated the issue and took our A 220 to the local Mercedes-Benz dealership for a thorough inspection. The dealer’s technicians confirmed the problem, noting “harsh clutch engagement and shift characteristics.” Utilizing diagnostic tools, they performed a quick test but found no fault codes related to the transmission concern. A fluid level check of the Dual Clutch Transmission (DCT) was conducted and deemed within specifications.
To address the rough shifting, the dealership performed full basic transmission adaptations. This process essentially relearns the transmission’s shift and wet clutch application characteristics. According to the service printout, this adaptation aimed to restore the smooth shifting behavior. Post-adaptation, a quality control road test was performed, and the technicians reported a 99% improvement in shift patterns and clutch application in both Comfort and Sport modes.
Upon picking up the A 220, the service advisor confirmed the performed adaptations but seemed hesitant to acknowledge a mechanical issue. Instead, the advisor attributed the previous rough shifting to the inherent nature of a DCT transmission. While DCTs can exhibit some minor jerkiness in certain situations, the severity of the issue we experienced in our A 220 felt beyond normal, especially considering its initial smooth performance. Despite the successful adaptation and resolution of the rough shifting, the dealer did not charge for the service, adding to the somewhat unclear explanation of the problem’s root cause.
Adding to our Mercedes A 220 ownership experience was the scheduled 10,000-mile service. This routine maintenance included essential tasks such as an oil change, tire rotation, and brake inspection. While the brakes were found to be in good condition and the oil change was completed without issue, the tire inspection revealed uneven wear, leading to a recommended wheel alignment. Consequently, in addition to the standard service, we opted for a wheel alignment to ensure optimal tire wear and vehicle handling.
The final bill for the 10,000-mile service totaled a significant $617.59. This cost broke down as follows: $229.95 for the alignment, $285.69 for the oil change (including 6 quarts of synthetic 5W40 oil and a filter), and $101.95 for tire rotation and balancing. Opting for the convenience of the local dealership and needing the service completed promptly, we did not negotiate on pricing. However, given the considerable expense, we are considering exploring independent service shops for future maintenance, such as the upcoming 20,000-mile service.
In conclusion, our experience with the Mercedes-Benz A 220 has highlighted both its sophisticated technology and the potential for unexpected issues. While the transmission rough shifting was successfully addressed through dealer intervention and transmission adaptations, the 10,000-mile service revealed the relatively high cost of maintaining this luxury compact car. Prospective A 220 owners should be aware of potential DCT transmission quirks and factor in potentially higher service costs compared to non-luxury vehicles.
