If you don't want to add Rheingold/ISTA that's ok too - you'll have a working copy of INPA and NCS Expert. This makes your diagnostic system capable for a wide version of BMW's including e46 all the way up to Fxx series cars. So once you install the simplest install version of BMW Standard Tools ever produced you can add Rheingold/ISTA to your new BMW Standard Tools as it uses the same EDIABAS 7.3.0 program for comm purposes - with existing K+DCAN cable. Rheingold/ ISTA is the current Dealer Level Diagnostic tool for diagnosing and repairing your e46. What's great about having a known working copy of BMW Standard Tools (INPA, NCS Expert, EDIABAS etc.) is that it is a prerequisite to upgrading your system to support Rheingold/ISTA. A while back he created this single one click install that will detect your Windows version and make the necessary modifications it will even install the correct USB drivers for your Amazon or eBay K+DCAN cable. It's never been easier to install BMW Standard Tools thanks to Stylinmike over at Bimmerfest. Well these days of install confusion with INPA and configuration issues are over? Even the thread titled NOT SO EASY sees the OP frequently having to remote access the owner PC trying to resolve install issues for this not so difficult version. At least 10 times a week or more there are new posts about INPA. This is why every e46 owner needs a working copy of dealer level software. Good examples are Brake Module replacements, or Steering Angle Sensor calibrations. Now tools like OBD Fusion and PA Soft might all be part of your arsenal for an e46 but there are times when neither of these will do the job.
