I've got to say after having two very close calls in my D1 with faulty ABS, I think I feel safer with it disabled. The first time was coming up to a junction on a dry road in the summer, going fairly slow, plenty of braking space and one wheel went over a very small patch of gravel - small as in 10-20 pea sized stones - and this caused the ABS to activate, which was fine, except it then didn't deactivate and it caused me to slowly drift right up the edge of the main road junction with minimal braking.
The second time was when I was pulling into the car park at work, which is slightly down hill and the spaces end with a kerbstone and a 5ft drop over the wall. As I turned into the spot there was some gravel again and one front wheel skidded slightly, as I was braking and on full steering lock, downhill. Again the ABS came on and stayed on and I nearly ended up going over the wall except I was a bit on edge about the ABS so I grabbed the handbrake just before I hit the kerb.
In between the two incidents I replaced two faulty wheel sensors, reseated the other two, cleared all the error codes stored in the ecu (after fixing the faults one by one) and had several test runs, trying to reproduce any faults and seemingly not finding any. The ecu was clear until the car park issue, at which point the ecu was faulty.
I bought a s/h replacement, but after fitting it and finding other error codes even after clearing and troubleshooting, I just have no confidence in the old LR/Wabco system anymore, as when it fails it just seems to fail with the brakes open. And given the age of the thing, there is an ever increasing likelihood the parts will fail as the vehicle ages.
What I totally fail to understand is why the failure mode of the system doesn't just disable the ABS, instead of the most critical safety system of the car.
