After I cleaned EGR system, no emission related errors appear. The emissions cooler (3) was full of soot, also the valve(2) shifted badly...
No I am about to clear DTC, but no success with ELM327. I can read codes easily, but after clearing it the same code is still in ECM. Or may Volvo doesn't allow to access this area of ECU ???
Has anyone experience with ELM327 vs V70 D5 ?
p.s. How to convert general OBD codes to Volvo equivalent? (P04010 -> ECM-4405 )
