limp mode usualy occurs when the ecu detects a boost spike. It puts you in limp mode to protect the engine. Have you had any mods done?

the car has had a bmc induction kit, 4 bar pressure regulator and a n75j valve which i had put on to try and stop the problem as the standard one was what seemed to be causing the problem
