P270E reports an over-temperature of the shift element labelled E. Because the value is normally calculated rather than measured inside the clutch, a wrong input can also trigger it: an implausible fluid temperature signal or incorrect slip data from the speed sensors would distort the estimate. Before suspecting the clutch, check for stored sensor codes such as P0711 or speed sensor faults, and confirm the fluid level. If those are fine, real slip of element E under load is the likely reason. No vehicle maker documents P270E publicly; Audi's S tronic bulletin for the 2010-2012 S4/S5 shows a related case under maker codes, where poor contact on the mechatronic circuit board produced clutch temperature and torque limitation entries. The car usually stays drivable with reduced performance.

Likely causes

Faulty fluid temperature or speed sensor signal distorting the calculated temperature

Real slip of element E under load

Poor internal contact in the transmission control electronics

Low fluid level

Symptoms

Gearbox warning with reduced performance
Additional sensor codes stored
Slipping or delayed shifts through element E
