Summary Verdict
The 2007 Volkswagen Eos presents a mixed reliability profile. The 2.0L Turbo engine has known issues with PCV valves and carbon buildup, requiring attention. The DSG transmission, while offering smooth shifts, is prone to mechatronic unit and clutch pack failures, which can be costly repairs. The retractable hardtop roof system is a significant feature but also a common source of problems, with hydraulic leaks and sensor issues being prevalent. Electrical components like window regulators and infotainment systems can also develop faults. The 3.2L VR6 engine and manual transmission appear to be more robust. Overall, potential buyers should be aware of these specific potential issues, especially concerning the powertrain and the complex roof mechanism, and factor in potential repair costs.
