The fault is "Reduced Engine Performance", performance seems normal and it would reset after the engine had been stopped for a few hours. Over the last week I have also now been getting the engine management light come on. I have code read with a ODBII reader and the only error code is P00BC (MAF low air flow). when i look at the data it shows the MAF is working normally (39g 2000rpm, 63g 3500rpm). However when the fault happens the EGR is reading EGR Duty 0%, EGR error 99%. When the error is not present is reads normal (EGR duty 38%, EGR error 0%).
Do you think its an EGR valve issue? or will the MAF cause the EGR to close? I have just purchased a used MAF and waiting for delivery.
Car has full Volvo service history and was only severed December 2018

These readings look very similar to the problem I am now suffering. How did it get resolved?
Thanks, Gavin
