Hi, I took my 2017 Audi A4 for transmission Fluid change at 45k miles at the Audi dealer 3 days ago and I did an OBDeleven scan just to check everything today( NO lights on dashboard) and this code came up (P187E00) "oil pressure reservoir Pressureless" is this becase when they drained the fluid the system recorder this fault and should I just click CLEAR Faults or Do I have to take it to the dealership right away?
Also, I am new to OBDeleven and Audi vehicles but for my understating passive faults are errors that were recorder maybe a few times but dont represent a major problems and active is when something is really bad right? Also,if I cleat this passive code how long would it take for the fault to come back up after cleared?
And what does priority 4 ?
sorry I have many question.
Thank you so much in advance

Tbh they should have done a diag log & cleared then driven then logged again to make sure all was clear, I'd give them a call tbh as either they didn't log it after the work or just didn't clear the old errors.
