I can understand a pump, but how does a steering rack go? My old car was a 20 year old fox, and it never had a steering rack replacement. Grrr

Not looking forward to that one.
Okay let me give you more info;
When I got mine (brand new early 2006 model) all was fine...
Two weeks after purchase I started feeling a weird shudder on the steering wheel, pedals, basically the whole front end of the car.
This happened only under VERY specific conditions; when making a hard turn (90 degrees or more) at a slight incline, especially on an uneven surface at a low speed (5 to 20km/h) and never when the car was cold.
Took it in immediately, was impossible to recreate the noise + shudder cos at the time it seemed intermittent and i also did not yet know the exact conditions as outlined above.
So I procrastinated till the first service...they found nothing, second service...nothing...by the time the third service rolled by, 18 months had passed and I knew exactly how to recreate the problem, so I showed the technician at Hatfield VW.
He investigated the problem and eventually concluded with the help of the factory data that it was a minor factory fault that affected some of the early 2006 models.
(The interesting bit was that he mentioned it was also present in the previous model polo classic).
It was related to some friction being created between the pump its attachments and the rack as far as he explained it, i don't know how accurate that information is.
I did a bit of research on the net about the issue, it wasn't exactly a widespread issue but the people who did talk about it on the net were quite satisfied after a steering rack replacement (or so it seemed) however my attempts to have it repaired under warranty were futile, others out there had more luck.
This is why I mentioned it on the thread before...
Anyhoo,
Because of the weird way that the sound + shudder is created you may never experience it even if the fault is present on your vehicle.
On a slightly more positive note; after that whole story I was nicely surprised one evening when a car thief did me the huge favour of collecting my vehicle from the roadside and not returning it, thanks Parkhurst car thief.
I owe you and the insurance company for giving me my new car without steering rack issues, actually no wait I owe you nothing.
