Hello, today I was coming back from the mechanic where I reported a fault consisting in not burning the mixture in my Jetta 2.5 b+g, he uploaded it to the computer and showed 11 errors - regarding the cylinders of the lampda probe and the flow meter, he erased the errors and it turned out that in the first place the flowmeter needs to be replaced - he removed it - however, it turned out that no store currently has it in stock, he put it together as it was and went home, on the way back the following information lit up for me:

the message dies at a standstill when the box is on "P" and when I drive it appears for a few seconds later it dies and the red oil icon flashes, may it have something to do with the box?
