Hi folks, I also have restricted performance :( 2010 XF 3.0D S portfolio 95k mileage. This happens mostly between 1800 to 2000 RPM with gentle throttle pressure, but occassionally does happen under hard acceleration. I have had a smoke test done (not convinced by it though) and nothing was shown. I have cleaned both MAF sensors (one was very dirty) I have cleaned the MAP sensor which was very oily There is Oil visible between the heads - more so on the right side (primary egr side, left side of the vehicle, near side), but no visible cracks on either manifold, and nothing visible on the throttle body. I have tightened the 2 bolts attaching the plastic tube from turbo to intercooler Given the following codes, I suspect the actuator arm on the turbo bypass (under engine by sump) - it is moveable, but seems stiff - I can use a bar and push it from above (through top of engine bay). Both EGR valve actuator arms arm moveable fairly easily - I'm not sure how much resistance there should be though. Codes that show on my OBD scanner :- P006A and P00BF I had a local garage also scan for codes, and they unearthed the following. P115A low fiuel P2459 DPF Regen blocked P0235 Turbocharger/Supercharger Boost Sensor A Circuit P00AA Intake Air Temperature Sensor 1 Circuit (Bank 2) P22D4 Turbocharger (TC) inlet valve P244B DPF differental pressure P2458 DPF B11DB Battery Monitoring Module P065B generator control circuit P22C5 Turbocharger (TC) outlet valve P060B Internal control module analogue to digital processing performance P22D2 Turbocharger (TC) inlet valve P22CF Turbocharger (TC) inlet valve P2192 System too rich at higher load Bank 1
