My 2001 Boxer with the 2.8Hdi engine has started going into limp mode, red 'injector' light on, loss of power. This happens at random, lasts for a few seconds or a few minutes. Otherwise the motor runs really well, can handle most motorway hills in top gear.
Being a 2001 model it does not have a full OBD11 port, only the 2 wire K-line system. I have an adapter to OBD11 but cannot get any sensible readings. I tried an Ebay Lexia without success so sent it back. Trying to think logically I assume the minimum signals the ECU needs is RPM/crank position, throttle, temperature and manifold pressure/airflow. As the engine still runs smoothly in limp mode I assume there is no misfire so suspect either a bad throttle position indicator or something to do with the airflow, turbo waste gate sticking or bad manifold air pressure sensor.
i assume the crank position sensor is OK as no misfire.
Engine hot or cold seems to make little difference.
Anyone got any ideas?
