Engine Performance Complaints/Check Engine Light On with Code 2511 and/or 2355

If you receive customer reports in the above model vehicles of the engine being in limp home mode with the check engine light illuminated with fault code 2511 and/or 2355 stored in the engine control unit (ECU) or the engine is surging/hesitating/misfiring at part load with no fault codes, perform the below procedure to resolve. These may be caused by the EGR valve temporarily binding and consequently exceeding the set point and causing the fault code and limp mode condition; or the software version in the engine ECU (lean condition under certain RPM/load, temperature and fuel quality conditions).

To resolve, install modified EGR valve (see parts information) combined with ECU software update (available as patch 2005-10-13-0474 with DAS update 10/05 and later DAS updates without patch).

Note:
It is important that the modified EGR valve is installed together with the modified engine ECU software and vise versa.

Note:
After the software flash, perform SCN coding (refer to Star Tekinfo Document S-B-07.61/38g or S-B-07.00/144) and verify injector coding.
