Took my grandmother's car for a subframe bushing replacement on her jetta, I noticed that the engine had the same back and forth movement as it did previously, after inspecting the "replaced" part I discovered that the part was the original part the vehicle came with and was in fact never replaced. The following day, a Monday I went to Velocity Motors to express my concern with the owner Brent, that concern was that the part looked too old, had too many cracks and was too dirty for 50 miles, he became very rude and hostile and kept saying I was accusing him and his business of I don't know what exactly, and even asked me to leave. I did some research and discovered that Volkswagen has revisions for their parts, the original part that came on the vehicle had a B stamped on it which was a part that was stopped being made, the new parts i purchased from the Volkswagen dealer for the second time both have Q's stamped which is the only revision you can purchase from the dealer, I even asked the part salesmen if he could print something out where it shows when the revisions occured, even after these facts, the revision documentation and the visual condition of the part I asked for a refund on the parts that were never installed and the owner Brent just has become more hostile and even threatened to call the police. Not only did I over paid for the service, but I had to purchase the parts two times, and now I'm being threatened to have the police called on me. The first picture is of part 1K0199868B, which is the original part the car came with, the second is 1K0199868Q which is the revision version of the part. *Update Just received the subframe back from Velocity with the second set of parts I purchased and needles to say it came back improperly installed and broken, I've updated the pictures with the results.
