V60 D4 VEA Reduced Engine Performace
Hi All
I have been getting a intermittent fault with my 2014 (MY 2015) V60 D4 VEA 74k. 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 |
