Hi
I am having issues lately with the EGR valve and fault codes my Audi is a 2010 2.0TDI 140bhp
The fault codes that I get are
4891-P0403-EGR Valve (N18)-Malfunction open circuit
4892-P0403-EGR Valve (N18)-Electrical fault in circuit
These codes came up a few months back so I had the EGR valve cleaned which did not solve the issue so i had it replaced as i was advised that the electrical fault may be due to the solenoid valve on the EGR malfunctioning this seemed to cure it for a couple of months (1500miles)
However the fault codes have now returned
When i press the accelorator whilst driving there is a short dip in power as if the engine is starved of fuel momentarily this happens a few times then the glowplug light comes on and the car goes into limp mode this will happen on every journey now it will also happen whilst driving along the car dips and pulls a couple of times
Its booked into the garage to get the wiring loom looked at to try and find the electrical fault but failing that im not sure what to do with it possibly looking at getting an EGR delete kit fitted or a remap
By the way all this trouble has occurred since January when the car was recalled and had the new Audi emissions software installed which im starting to think is not a coincidence
Any help /advice would be appreciated
Thanks
Lee
