Ok, well, what are the current trouble codes you are getting? Based upon the codes you are posting; I'm assuming, you have a generic obd II scan tool. To read ABS and other possible related problems; you probably, need a VW specific scan tool, like VCDS by Ross Tech or equivalent (OBDEleven, other VAG scan tool, etc), to read those specific VW factory trouble codes, which can narrow down the issue. If you get more codes; and/or a scan with a VW compatible scan tool, please post any codes you get and we can go from there, to figure out why you are having the "beeping" issue and the various lights are on, in the speedo cluster.
You have already, "gone deep down the rabbit hole"; in during in depth repairs on this Volkswagen, further diagnosis and troubleshooting, pretty much requires the use of a VW specific scanner with factory level capabilities, like VCDS by Ross Tech, it is a investment @ $199 but totally worth it, I have been using it, since 2007, when my factory VW warranty went out and it has saved me thousands in repair costs and my car literally, would not be on the road today without it.
At the end of the day, either you pay someone to diagnose things; and they will be using a VW factory level scan tool, costing you most likely more then buying VCDS or you fix it yourself with your own equivalent tool; VCDS, enables you, to gain control of your diagnostic, troubleshooting and repair process, which finally, completes the missing capability to truly "see", what the onboard VW proprietary diagnostic system sees and this is a very powerful way, to finally stop "flying blind", eliminate the guessing, speculation, about what is going on with the car. This will help you to finally, allow total access; to all the live data, factory vw codes and ultimately, hopefully, fix your car. When you get the tool; you can tell us the factory VW codes, that are coming up and then, do more in depth testing and if needed, look at live data, do output tests, etc. Let us know, how you want to proceed with your diagnostics, troubleshooting and repairs (get access to a vw scan tool allowing you to diy, take it to a pro shop, have then handle it or "punt", etc), we can go from there. Thanks.
