Iv just bought a A6 Allroad 3.0tdi, got a dpf delete pipe on the way and was wondering would it be wise to blank off EGR when i take it to be mapped? Having Adblue delete aswell, just trying trying to remove anything that could cause harm in the long run. Not hugely bothered about the performance side of it.

Cheers

We're seeing cases where people have e blanked/deleted the dpf and egr and then they experiencing other engine issues as the engine runs hotter. 

If you're deleting the egr it might be worth just blanking it off when getting it deleted from the map. Because if the egr can be seen easily by an MOT tester normally and they notice it's missing then you could end up with a fine as they can prove you've tried to tamper with the vehicle emissions. It might be under the engine cover in that case it's not so bad as MOT testers can't remove parts.
