Its such a lottery!TBF, I only had my EGR valve bypassed with a blanking plate that cost less than 5 quid, the ECU needed remapping, all in it was £290. Vehicle runs like a dream, and two years on, the blasted light has never blinked. Apparently, the modification turns my Euro 6 engine into a Euro 5. Passes the MOT every time![]()
Having had to take my Discovery Sport to my local independent JLR garage twice in the last 18 months to address 2 red dpf/reduced engine performance faults that my fairly top-end Autel diagnostic tablet couldn't address, many of my colleagues advocate a delete/re-map but that is as others point out illegal and constitutes a MOT fail as the OP has discovered. However, it does seen to be fairly common practice to do a full dpf delete but the MOT garages turning a blind eye to this are breaking the law - such as lottery.
