Got my car worked on because of a intake manifold flap issue with my GTI (or so I thought) took it up there and they told me they t was covered under warranty. Got a call day later saying that they needed to go deeper and complete the full troubleshooting process. Raised the bill up to 400. The car was fixed the next day, but it turned out to only be the spark plugs from what they told me. I basically paid 400 bucks for my spark plugs to be changed. Now my car has a vacuum leak and the same intake manifold code which they also noticed and said to come back when it clonks out. So the initial issue I went in there for hasn’t been fixed and I still have the same issue and more now. After I went back to see about the warranty, they refused me service because I gave them a bad review on my survey. Super unprofessional and childish.
