so, did a scan today, out of the blue and these came up:

after i cleared them, 16406 didn't come back, however i didn't drive the car after clearing them, only idling and then re-scanned it.

I didn't notice any poor performance, i came from a 60mile trip, and all seemed ok.
My concern is the 17942 code, the EGT one doesn't worry me that much, i can fix it hopefully with just re-soldering the wires, as the DIY here on the forum.

What i did notice, after doing the scan, was that the typical noise i had between 1100rpm - 1200rpm is no longer present, so that means that the tensioners don't work anymore.

Anyone has any clues? should i go ahead and buy new tensioners or could be the solenoids?
