if you have lumpy idle and sooty exhaust then its likely injectors will need doing. easy way to confirm this is pop the spark plugs after one evening.. this will tell which are leaking as the plug will be wet.
Index 11 are a big improvement. parts cost is 900£ for 6 injectors from merlin + decoupler rings £40 from Harry Fairborn..
Personally yes id remap and dump the NOX system..

Thanks for the response Will. I’ve done as you advised and multiple Nox errors have come up again including the ageing Cat. Hence I’m considering doing the mid Cat delete and mapping the sensor out. P-torque offer this and I’ve had good experience with them before on my 125i.
I’m just a little confused, by mapping the Nox out and deleting the mid Cats, would the car still run stratified as per normal and I wouldn’t get any more Nox error codes? What would be the difference between a Nox delete and lets say the Noxem etc.
Thanks again
