I had a "check engine" light (Peake tool code-"VANOS, exhaust mechanically stuck") and took it to a garage in Finksburg, Md. I picked it up, after a VANOS actuator replacement ($3K), and had the identical engine code within a few miles. The garage then indicated, after their initial attempt, that it now needed a new timing chain and sprockets for an additional $4K. I didn't trust their judgement and brought the car home.
The same code has come up sporadically over time, with resets, and now about every 20 miles. It has never changed through the RMW vanos actuator replacement. Any thoughts on actual engine problems related to this code?
