Jay1710 Posted October 20, 2023 Share Posted October 20, 2023 My a4 is a 57 plate with 110k full service history. I want to do a egr delete as I think this would improve performance and fuel efficiency? Is this true? Any is there any downsides to it?

Steve Q Posted October 20, 2023 Share Posted October 20, 2023 Downside, if you're caught by an MOT tester then it's a fail and a fine. Even though this should be unlikely to get caught Quote Link to comment Share on other sites More sharing options...

But if the MOT tester is eagle eyed and notices it missing then he can fail it. Quote Link to comment Share on other sites More sharing options...
