Hello, I’ve already been looking “passive” for the problem and also found clues to solutions. My problem (Volvo V70 XC 2.4 Turbo 193 ps, BJ 2000, KM 162.000): Engine light burns, engine jerks when accelerating, especially from approx. 2000 rpm. It does not bring full power I have exchanged: – TCV – spark plugs (against original Volvo) – petrol pressure sensor After swap TCV it was gone – Turbo has also “pitched”. Since the engine light still burned, I once stuck off battery overnight I switched spark plugs and petrol pressure sensor. No change. Now I was reading out at Volvo error. A lot came out: – ECM-2810 Front heated Lambda probe group 1 – signal too low – ECM-2A0A Rear heated Lambda probe group 1 – signal too low – ECM-2A2A Rear heated Lambda probe group 1 – signal too low – ECM- 4000 Activated carbon filter valve – signal too low – ECM 6800 Turbocharger control valve – signal to ni edrig (actually already exchanged?) – ECM 9300 Clutch pedal positioner – Incorrect signal (tempomat does not work – therefore probably) My question – before I go into the long search: Does anyone know if the fault codes Lambda/Active carbon filter flush valve/turbo loader control valve can be connected, i.e. the cable strands together or on a fuse? It is strange that the TCV has been changed but should already be defective again. Thanks for your help e! Greetings Peter
