Fault Code P0490

29 November 2012 - 11:21 AM

Mk4 Mondeo 2.2l TDCi Tit X 2008
Out of the blue my motor is losing boost and garage came up with fault P0490 EGR Control Circuit High and suggested I need a new EGR valve, my handheld tester comes up with P0131 O2 Sensor Low Bank 1 Sensor 1 and P0299 Turbo under boost. When these codes were reset I drove for about 10 miles then same fault - no boost and won't rev over 3k, stop and switch off and all ok for another 10 os so miles, This has only happened since it was serviced (at dealers) and new brake dics and pads fitted other than this nothing has been touched. Any ideas??
