2.7T Engine Notes Technical Support

The 2.7BiTurbo engine is a fantastic engine but even new earnt a reputation for having a relatively high number of small component issues, given the age of most vehicles with the 2.7T engine it is important for the vehicle to be 100% healthy before having any performance software installed. If your vehicle has any running issues in standard form our dealers will be able advice on how to proceed with rectifying issues. Any running issue needs to be resolved before the vehicle can be upgraded.

Typical issues with the 2.7BiTurbo engine are:

  • Split/Failed Diverter Valves
  • Coolant temperature sensor failure
  • Throttle body boot splitting
  • Y pipe splits/leaks (on vehicles with plastic Y Pipe)
  • Cam Cover gasket seal leaking
  • EGT sensor failure
  • Lambda probe sensor failure
  • excessively 'aged' Spark plugs (due to the location of the coil packs/plugs they are sometimes 'missed' when serviced)

NOTE: this is not a full comprehensive list just an overview, do not be put off by the above information most vehicles can and do suffer from vehicle issues.

When building a Stage2 specification car you can run a de-cat or sports cat without getting a Cat efficiency DTC however the rear lambda sensor still needs to be plugged into the wiring loom as this is not deleted.
