Really appreciate the advice. I'm a VAG man at heart and usually use VCDS for any live data. Could you recommend a suitable software / scanner solution which is capable of reading and logging live data from these disco 4s?

Thanks for the suggestion, not heard of them before but I'll certainly check them out and look for any ideas.

It does yes, I have tried both D & S and also tried the multiple terrain options e.g. sand mode and that makes no difference either.

Hello forum, I have a 2012 Discovery 4 SDV6 which suffers from “lag” when setting off from stationary. I had it mapped by Alive Tuning to resolve this issue however it didn’t appear to make much difference. I have since tried 2 new MAF sensors which also didn’t resolve the problem. Any advice would be greatly appreciated as it’s gotten to the point where it is dangerous pulling out of junctions and I no longer have confidence driving the car. For reference, I also have a 2015 Discovery 4 with the same engine and similar mileage however this doesn’t suffer as much as this one. Please see the following video where the car is in “D” drive, and I take my right foot off the brake and then straight on the accelerator. You can see the car takes its time, almost crawling off the line before whoosh, it takes off like a rocket ship: https://www.youtube.com/watch?v=ZWQz32Kaw_g Thanks, Ben
