Interesting about reluctor ring. Had one break on my old Audi A4 V6 rear drive shaft. Straight forward to replace. Need a scan on the system to isolate the faulty speed sensor, and invariably will be a bu**er to remove.

Fortunately the speed sensors are a dream to replace, can do it with just the wheel off and a 5 mm allen key.

Reluctor ring on mine was a m**********r to remove. Nearly broke the indy's tools just getting the driveshaft pressed out [emoji51]

i read the same thing online about the transfer gear actuator causing them all to light up.  if you go on You Tube there are videos there showing how to remove it,  you can change the toothed wheel inside that gets its plastic teeth stripped away, looks a fairly easy thing to do, you need ramps though. You can see the part by looking in the area sort of underneath the car where the passenger seat is.
It may be that  or not.  You can get the plastic toothed replacments from Amazon for about £10

So it was the ABS sensor. Bit of a hassle. They checked the reluctor ring, which I believe is fine, (the wife took it in so there is plenty lost in translation)  but their parts supplier sent the wrong part. Ordered a  BMW part instead which I'm happy with and it will be fitted Monday. Around £150 or so sparing any hidden treats.

Good good. If they fit it and find the reluctor rings to be at fault. They have to replace the sensor again and probably at no cost as it wont be your fault they didn't fully check the the reluctor ring.

Just to conclude. ABS sensor replaced with BMW one. £102!!!
Wiring from ECU to sensor was shot so was replaced. Turned out a bit more pricey than expected. Still,  just another three slowly degrading beneath me.

Good work [emoji106]
At least you'll know what's wrong the next time.

If they discovered the wiring was knackered after they fitted the new sensor, chances are that there was nothing wrong with the sensor in the first place

Highly likely!

Step 1 check the sensor is doing what it should?
Step 2 on a 'no signal' condition, unplug the sensor and check it at the connector.
Step 3  if sensor within tolerance, trace wiring back (with a test source connected) to wire source and identify break point.
Step 4 fix it!
Step 5 reassembly is the reverse of above, static test, road test and if condition cleared give back to customer.....if not then you missed something!
