My girl friend drives over 3 years with EGR off file and regeneration works fine, but it is a EDC17CP14

Today I made egr off on audi a6 2.0 tdi 2012...

Howeever same ecu edc17c46 and same engine...

When i made it i checked readiness in vcds an look at photo... Before I made egr off there was egr failed status but now it writes >Not installed<

There must be something wrong with egr off on some sws because on audi a3 there was still written egr failed...
It is not only about this car but also on some other 1.6 tdi and 2.0 tdi...

There are few % of total egr of made that make problems

You can see your egr valve in % look at measure blocks.

Can someone pls make complete EGR off? i have DTC P0403.

Do you have news for EDC17C46 egr off without dpf removal? Is it only possible with pre-dieselgate sw? Or it doesn't matter if we touch normal mode hysteresis only?

Just touch normal operation hysteresis , dpf works fine

Hello, is there a solution found?

I have exactly the same hw/sw as the first version, and I guess I'll have the dpf problem. From now I switched hysteresis maps 1 2 4 5 to 0 and P0403 off but I still have limp home mode when oil temparure > 70°C, I guess "normal maps" are 3 and 6... but it looks like Johak's map, that seem to cause dpf off also.
If I unplug the connector and make a dtc off of the error that will occur, can it be a solution?

Thanks
