I purchased a 2015 VW Golf with the 1.8T gas motor. I took it in for emissions and it's calling for a pre OBD2 2 speed test on dyno rollers. It will not give the emissions tech an opportunity to plug it into the OBD2 port at all. Guy said he has never seen it before and didnt have the dyno equipment to do the test. I have no CELs at all. Anyone ever seen this happen?
