Recently bought a Foxwell NT510 (use it for Land Rover and 2009 Passat CC 2.0L TDI - has software for both vehicles loaded).

Anyway, yesterday and today noticed the glowplug amber light (wife descriptively calls it the "Curly Wurly" light) came on and started flashing, then of the course the EML amber light followed. At this stage no issues with power or anything else.

So, today I attached the Foxwell NT510 with the vehicle in the driveway and turned ignition on to read codes. The Foxwell showed "01027 exhaust gas recirculation circuit" as the only fault code present.

Interestingly, the first time the "Curly Wurly" light came on yesterday I stopped the car and turned off the engine and opened the bonnet to look for anything obvious - even though the engine was off I could hear a buzzing sound (like a bee or wasp) from under the engine cover; I don't know if this is linked?

So seems like this fault code may indicate a problem with the EGR vacuum solenoid?

Is anyone able to assist with this problem? Is this something I can easily check and fix myself?
