You need to use picoscope to identify noise source… it is system including microphone/ microphones placed close to suspected noise source. My tranny noise did not have any relation to weather conditions.

hi again, Differential and it’s bearings replaced, noise is GONE. Jihuu, finally. Bearings have clear scrathes and pinion gears have quite strange markings… these could be bad machining or someting more severe… clear quality issue. From where did the particles come from, remains open question. Few pictures from damages attached.

hi, 2014 Audi A3 1,4 TFSI COD with 97000km and I have been heavily struggling to find reason for ”rubbing” ”noise from front of the car when turning to left. Noise is gone when driving straight or turning right. I have changed myself: front wheel bearings, left driveshaft and left top strut bearing… these were not a solution. Car is at the moment (2.11.2021) in our local Audi dealer workshop for gearbox check… I got today information, gearbox is disassembled… differential and it’s bearings are damaged… RCA found! They have repaired ”few” (as they said) similar cases during past years… I have a strong feeling that this is a quite common issue on these cars. Repair cost estimate is now 3000eur, let’s see where we land in the end. Juha
