At the 39,000km mark, rear right wheel speed sensor failed and was replaced at the service center, total expense @8k (part, labour, taxes). Auto Air Filters
At first, when I called, I was told the sensor may not be in stock, scan will confirm which wheel sensor has failed, all 4 are distinct part numbers. I just drove to the service center and asked them to check. Scan revealed rear right - they confirmed it's not in stock as a loose item, but they have a kit of all 4 that I should buy as other 3 would also fail soon. I asked to speak to their Inventory person and asked him the ETA for the single sensor to arrive if ordered today, considering BMW took just 1 day to get the front left wheel speed sensor that failed on my 330i a few months ago and there was no such fuss about changing all 4 (may be because they were going to pay for it and not me thanks to BRI ) At this point, better sense prevailed and he agreed to "break open" the kit and sell me one out of the 4!
Since this, GTI has done 2000+ km and the other 3 sensors are fine. 330i has done @5000 km since the sensor replacement and other 3 on that car are fine too
For the records: wheel speed sensors never failed in the Laura 1.8 TSI in 8 years and 58000km of driving, neither did they fail in the Polo GT TSI in 4 years and 44000km of driving.
