I have a P2000 code that I'm unsure of how to deal with. It came up about a month ago, and I wasn't able to clear the original code right away, but after several attempts over a 7 day period it did clear. Now it is back and again won't clear. I don't have a nearby VW shop, so in the past I've replaced the odd sensor ( Boost presure twice) with success, but this one might be covered under the dieselgate fix warranty. Anybody have thoughts on this, and what the issue might be..?
