The MIL may not come on all the time, but there still may be sporadic faults stored in the ECM. If you have a reader, look into it!VWT1994 Mine is a late build 2019 Se Tech RLine VR6. 4,200 miles. Head replaced 200 miles ago. Been stumbling randomly at idle since I picked it up 2 weeks ago. No check engine light yet. Plenty of warranty left.
