The following are alleged to cause the "three amigos" problem on TD5:
1. Worn or non-genuine brake shoes (said to be no.1 cause in US). Rattle or squeal can apparently activate sensors. One user reported that a rattle from a loosely secured brake pipe had set his off.
2. Faulty earth connection behind n/s headlamp.
3. Failed sensor.
4. Damaged wiring.
5. Damp or dirty harness connector at hub.
6. Early SLABS ECU software. Replacement with later part no SRD500070, which has better software with a wider tolerance, may solve problem.
7. Badly seated replacement sensor. Apparently may be difficult to seat the rubber O ring correctly on the Disco II, and this can cause the sensor bracket to bend and give incorrect gap. One mechanic suggests replacing the rubber seal with a very small amount of silicone sealer.
8. ABS modulator switches. It is possible to service the switches without replacing the modulator (LR service kit)
9. ABS modulator unit. Probably not economic to replace on this car.
10. Play in bearings
11. Modulator caps recall. There was a recall to replace the modulator unit caps with thicker ones. Part no B148.
12. Unequal tyre pressures.
On mine it was the SLABS ecu. You will need to get the system hooked up to TESTBOOK, which will give some idea of the fault and also reset the warning lights. It's usually a sensor problem, but if it's an early TD5 with a front wheel sensor problem it may be the SLABS ecu. Lots more info elsewhere on forum
