DPF and EGR removal
 

I have an 2011 diesel A1 and I've been getting a few warning lights on the dash. My pal did a diagnostic test and it says its the EGR valve. After many discussions and a lot of reading forums we have decided to blank off the EGR and get the EGR and the DPF removed from the ECU professionally. I'm not concerned about getting the EGR removed as I have only had positive feedback about it but I am a little concerned about getting the DPF being removed as I have heard it may make the engine sound louder?? Any advice very welcome
