Is nobody else bothered about approaching Seat and wanting to hopefully get their arches sorted and for free then?

Mymorph has asked people to send general details about your cars to try to get a resolve on this (he's not asking for your addresses) and so far he only has two details: his own and mine. These are details Seat will need before even entertaining the idea of a mass complaint and are details you will give them if you go in yourself anyhow.
Everyone's quick to have a monk and moan but unless you all get on board with this and join together Seat aren't going to do jack, and everyone on this topic who has complained about their cars (regardless of whether you've spoken to Seat and got a negative response or not) will not get this repaired by them under the warranty.
Nothing may come of this and Seat will probably have excuse after excuse, but if you don't try you don't know and the longer people leave it the closer to the end of warranty it will be and the harder for us as owners to prove to Seat that is isn't just because the car is old and badly maintained. At least if people join together now it can go off to Seat and you never know what might happen. I guarantee if more members bother their asses and this ends up with a positive result when Seat see how many cars this actually affects everyone will soon be quick to jump on the band-wagon then.

Get in or potentially miss out is my advice....
