Audi 2015 A3 Quattro
 

HI All.

Was hoping for some thoughts.

APR Stage 2, DownPipe, ECU and Trans Tune, Liquid Moly and Spark Plugs changed for APR tune. This car was a sleeper all tinted out and smooth. Well...

All of a sudden while driving normally, the Audi downshifted to 2 gear, sadi it was safe to drive but would not come out of 2nd gear.

Ran trouble codes and this is what I get:

P0732 - Gear 2 incorrect ratio
P074A - Unable to engage gear 2 Synchniz aborted
10731 - Valve 2 in tran Part 1
10732 - Valve 3 in tran part 2
10657 - RPM Signal From ECU
10909 - Cooling Oil Valve
10906 - Cooling Oil Valve
10763 - Starter Enable From Selector Level Sensor System
21148,21153,21154,21155,21157,21159,21207,21181,17 178

Replaced Mech and all gaskets, Fluids and filters (Clean output), Car has had every service and no trans issues in the past.

51K miles (Yeah just out of warranty)

Any Suggestions? (Enter SMH Icon here)

Well Well
 

After putting a full charge to the Battery, can clearing al the codes. I have these now (only).OBDeleven data log
