Which sensor might that be? If you don't mind the time.

Cleared the fault codes and drove it again today - nice & easy.
"Service Engine Soon" light popped up within minutes. Same Fault Codes:

OF A5 21

My interpretation -
OF - Table OF in Fault Code Listings.
A5 - VANOS output stage, Cyl. #1-4
21 - Camshaft VANOS control, Cyl.#1-4

After perusing the Bentley Manual, it seems there may be a likely correlation between code 21 & the VANOS Control Solenoid.
"VANOS Output Stage" is an unknown.

This may be beyond my handy little code scanner's ability to sort out.
Anybody have a suggestion how to avoid THE STEALER on this one?

God bless you all....
