So I recently purchased a audi a4 1.8 with 120k for a really cheap price through an online auction. Plan on making it roadworthy again and then sell it. Runs and drives but it has a few vacuum lines unplugged that I cannot find where they go. Car runs great when first started then starts to run rough. From what I have read this could be because of the vacuum lines. The lines I am talking about run through the driver side fender. There are 2 of them and both of them also have a small wiring harness beside them that are also unhooked. Looks like they would plug in somewhere around the brake booster and battery but I cannot find them. I have done a search on it but came up with nothing and can not tell using the online vacuum diagrams. Please help
