Hello together, I recently bought a used V70 D3 with the engine D4204T9 240tkm, was for inspection with the dealer and they have read some error messages (ECM-P200A00 and ECM-P200977). Unfortunately I find not much information about these error messages. The AGR valve was changed by the previous owner at the dealer exactly 23 months ago. What I wonder is whether these error messages have something to do with the repaired (completely exchanged) AGR valve I would be happy if you could help me there. At the moment I have no problems driving, but could it be expensive at some point or what would you recommend? Thank you very much. Error messages are actively available according to the last reading(inspection): ECM- P200977 control circuit impeller intake manifold low (bank 1)- Mechanical error request position not reachable . ECM-P200A00 Switching suction tube, power bank 1 CEM-P167400 Software Control module damaged CEM-U030141 Incompatibility Software with ECM/PCM – System internal error- Allgeminer Errors checksum
