Two problems related to abs brake fail have been reported for the 1999 Land Rover Discovery Ii. The most recently reported issues are listed below.
Abs failure almost caused the vehicle to wreck, several times. Failure has occurred on several occasions, once in the last 4 months ($800) and now again, I have spent $$ to fix the hdc, tc, abs lights that keep coming on and causing the abs system to stop working. The abs modulator on 99 lr disco ii's I found out is defective, later models have shuttle valves that do not stick. Lr will not replace it, and the part is $1,800. I'm tired of throwing money at a truck we spent over $50k to purchase, and cannot use!.
Beginning at 50,100 miles, abs, hill descent and traction control warnings went off. Vehicle was stopped in regular traffic, no unusual weather or driving conditions. Dealer replaced 3 abs sensors and reset ecu codes. 200 yards after leaving shop, warning lights and chimes returned. Dealer attempted remedial work - error indicated stuck valve in abs pump - to no avail. Codes were re-set, two days later turning left, warnings and chimes returned. Land rover indicated that abs pump needs replacing is the only remedy (parts ~$2,000). Web search indicated that this is a very common issue with 99 discovery owners. Original recall work was done years ago to strengthen abs housing. Should abs fail at only 50,000 miles? been driving without abs since fourth time.
