Hello All,

Can someone please advise.

Car details are as follows

E60 5 series 525D 2007

Modifications - DPF Delete, EGR Delete, Cat Delete (empty), 530D Turbo, Remap.

Fault little or now power below 2000rpm and rough idle.

I've had the map checked and they suggest that the dpf and egr off solutions aren't right.

If i check with ISTA which is a bmw diagnostic tool I can see that the EGR activation is set at 5% ? should this not be at 0% because its no longer there ?

I'm thinking with it reading 5% this is probably whats causing my rough idle and power issues causing misfuelling etc ? because its reading the egr as stuck open ?

can anyone confirm please, if egr should read 0% after deletion.

can anyone possibly take a look at the ecu file

thanks.
