Good evening. So, I purchased a Dna filter and open retaining plate for an E5 Interceptor before reading it might trigger a warning light or limp mode. Well I fitted it today, let it idle for ten minutes, though that is likely not necessary, and took it for a good ride. So far no issues, I think acceleration is smoother and the induction noise is great which helps cover up that sewing machine noise that I was not a fan of. Apologies if someone has already debunked the E5 with Dna filter issue. G
