P270C Transmission Friction Element C Temperature Too High

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

With P270C the controller reports that clutch or brake C has run hotter than its permitted limit. Typical triggers are long slip phases: creeping in heavy traffic, holding the car on a slope with the throttle, or a trailer launch. If the situation keeps recurring under normal driving, the element itself may be slipping because apply pressure is low or its linings are worn, and the fluid should be checked for level, smell and debris. There is no public maker documentation for P270C; which element carries letter C must be taken from the gearbox's own clutch chart. Audi documents the same protective idea under its own codes for the S tronic of the S4/S5 (2010-2012), where a fault in the clutch cooling oil valve can appear together with the clutch temperature entries. Sibling codes P270A to P270F differ only in the element.

Likely causes

Creeping or holding on a grade with the throttle instead of the brake
Element C slipping from low apply pressure or worn plates
Faulty clutch cooling oil valve or restricted cooler (where fitted)
Low fluid level

Symptoms

  • Warning in the cluster with reduced power
  • Gear using element C avoided or held only briefly
  • Hot, darkened fluid
