Mondeo ABS failed - Onetap
The ABS on SWMBO's P-registered Mondeo seems to have expired. It was locking the front wheels under moderate braking and making a strange noise. Then it had an (unrelated) puncture. Then the ABS warning light then came on. Not a good day.

I haven't looked at it yet, but assume it will prove to be beyond my abilities. I would probably be ab;e to check that the wheel sensors are producing a voltage. Since others must have suffered ABS problems, are there any recommended diagnosis/fix routes, recommended ABS brake specialists or any other remedies other than a main dealer? This is in the Essex/East London area. All suggestions gratefully received.

"this would be better over in technical?"
I did contemplate it, but think the fix is a non-technical parting with a large wad of cash. Non-technical suggestions to reduce the largeness of said wad, or technical suggestions that may fix it are welcomed.

I'll check the fuses, but the problem started before the warning lights illuminated, so I'm not hopeful.

It is possible the fault is with one sensor. For a simple DIY check - disconnect each sensor and measure the resistance of each. They should read about 1000 ohms. If one is faulty it will either exhibit a very high (open circuit) or very low (short circuit) reading.

Also check the air gap from the sensor head to stator ring. If this is excessive then adjustment is required.

Also check battery / alternator voltage.

Check all wiring connections (including fuse).
