Thread: BID 21 Fault Code - Discovery 4

You may be surprised at the difference a dedicated LR code reader makes to being able to sort out what is happening. The amount of info that I can see on the GAP tool for my LR is substantial.

Thanks Drafrete - I'll see if I can arrange to have the codes read by a GAP tool

It was the engine that went into limp mode
