I took my Volvo to IM Autohaus when I started getting some ECU codes. Their mechanics were very knowledgeable and ran the diagnostics for me. They replaced the gas cap which was causing one code, and then another code kicked in, so they fixed that problem, too. I was really impressed by the fact that when I asked them to install an electrical pump that I had purchased, they did so, and in fact, encouraged me to purchase the part myself to save money. That was just super nice of IM Autohaus, and I really appreciated that kind of customer service!
