The DIS on my FSI is has displayed the low oil level yellow warning a couple of times recently. The (useless) dipstick tells me that there is still oil in the sump, and running measuring block 004, address 17 (Instruments) on VCDS is giving a live level reading of 56mm with the engine off and cold (against a low level of 31mm - rocking the car causes the live value to vary slightly, “Difference“ reading is 0). From what I can tell on a2-freund.de, this might actually be on the high side - possibly because I topped up a small amount of oil when the warning showed. The car has never used oil (aside from losing some recently when the oil pressure sensor failed, which I topped up without issue), and there are no sensor faults when scanned with VCDS.
If the oil level/temp sensor in the sump is faulty causing the low level warning, should the oil level read by that sensor via VCDS not also give a corresponding reading?
