So had an issue showing up as fault P006A mass or volume air flow correltion
have replaced both MAF then found a loose hose (hard plastic drivers side engine had become unbolted) so refixed.
In the meantime red DPF came up (no amber, straight to red) Took car to local Jag Indie who put his diagnostics on it and reckoned fault was clear and to get DPF regenerated.
Had company out yesterday to clean DPF. All signed off ok and no faults showing.
Took car out for a run and after 5 miles RP came back. Stopped engine and RP went but after another 5 miles amber DPF came on which went red after a couple of miles so no chance to regenerate in normal way, followed by RP return, it also sounds like a rushing of air under moderate acceleration.
Plugged my code reader this morning and showing
P006A mass of volume air flow correlation
P1246 turbo low pressure
P2463 DPF
Any ideas before I go mad
