Astra MK4 2.0 dti (W reg)
On starting the car from cold the ABS light remains 'ON'. If I immediately restart the car the ABS light goes 'OUT' and remains 'OUT'. If I stop the car for longer than a few minutes the ABS light comes 'ON' again. I have checked the wheel sensors and all measure approx 1,500 ohms except for the nearside front which measures 1,000,000 ohms plus. If this sensor is disconnected the speedo does'nt work. So I can only assume its o.k
Does anyone have any other suggestions for finding the fault?
