The 2012 Volkswagen Tiguan has been reported to have several common problems, particularly with its transmission. This article will explore these issues, including symptoms, diagnosis, and potential solutions, based on real-world experiences.
One Tiguan owner reported a series of issues starting with a check engine light. The initial diagnosis at a dealership led to a turbo booster replacement, costing around $800. However, this didn’t resolve a persistent unusual noise, later attributed to a faulty wheel bearing. Even after these repairs, the check engine light reappeared, prompting the dealership to recommend a full turbocharger replacement. Skeptical, the owner sought a second opinion.
Meanwhile, a new problem emerged: strange driving behavior and a strained transmission sound between 25-40 mph. Another repair shop couldn’t pinpoint the issue but acknowledged vibrations at low speeds. Online research revealed that this was a common complaint among 2012 Tiguan owners, with descriptions matching the owner’s experience. Many reported issues with the transmission shifting too early at low speeds, causing lugging, vibration, and a straining sound.
Forums and online reviews, such as those on Edmunds.com, pointed to a potential solution: a technical service bulletin (TSB) addressing low-speed hesitation and noise in high gear. The TSB, identified as number 1-12-13 with transaction number 2029206, offered a software update to address the transmission issue.
The owner followed this advice and requested the TSB update at a different Volkswagen dealership. Initial results were positive, with the Tiguan driving noticeably better. This dealership also found a turbo-related code but, after inspection, determined the turbocharger was functioning correctly and didn’t require replacement.
This experience highlights the importance of thorough diagnosis and seeking multiple opinions when dealing with complex car problems. While the 2012 Volkswagen Tiguan’s transmission issues can be concerning, the available TSB offers a potential solution for the common low-speed driving problems. If you’re experiencing similar issues with your 2012 Tiguan, consulting a Volkswagen dealership about TSB 1-12-13 is a recommended first step. This case also underscores that a check engine light can stem from various issues, and addressing the root cause, rather than just replacing parts, is crucial.
