Has a Volvo V70 2.5T 2004 b5254t2 box number 0261207712

The car runs well but has an error code p0348 ecm-3010th Will not go through besikningen with it. "

What I done is changed the exhaust cam sensor and oxygen sensor, measured all three cables from the exhaust cam sensor, checked the power supply box for broken solder joints, you can turn off ignition and on and the error code back directly, but you start will be back on. But have discovered a funny thing, it is that there are two selenoider for intake and exhaust, when you start and stop the car so it is a strange buzzing noise from in the exhaust selenoiden which there is not intake selenoid. Have removed it and cleaned but still the same buzzing, the measurement of both selenoider after the engine stopped and the power given to both, does anyone know if it is normal for the buzz. My thought is that selenoiden is dead, another thing is that the car is optimized chip, but is optimized via OBD (non-brazed). Someone who had the same problem?
