Answer
Hi John,

sorry to learn that your '04 Disco has the "3 amigos" problem.  ABS, TC and HDC problems are common and I had thought newer Disco's would not be experiencing this.  

Before you perform any more component swaps, I would suggest you have the ABS fault code(s) read on your vehicle.  An experienced LR mechanic with a testbook analysis device can help locate where the problem(s) could be.   This may require a visit to your local LR dealer or independent LR mechanic.  Most local garages don't have this testbook diagnostic system.

It could be the modulator, a seal, wheel sensor contamination, electrical faults...an number of faults can trigger this.

Best of luck,

JohnMc
