I currently having problems getting mine sorted as the dealers don't really seem at all bothered. A bit short sighted in my view as it won't be long before I start looking for something to replace the 290BE!
I had the same experience but it looks like the dealer I use has gone through some staffing changes as the service manager now is very pro-active. I took my 290BE in december for its first (and only) service which was fine and they got the seat covers ordered on warranty, just waiting for them to arrive.
Overall my faith is restored, if I were you I would go to a different dealer if possible.
A bit of an update as well as (potentially) some more SEAT sloppiness!
After the first garage gave me the 'that's outside of the mileage/time scale' answer together with basically saying (without actually saying if you get my drift) that it was my fault, I decided to visit a couple of other local(ish) dealers to pursue the matter as SEAT Customer Services just wanted to side with the dealer. WTF?
Anyway, the gist from the 2nd dealer is that they don't think I have a claim but the service manager will be phoning me next week to confirm this as he's currently in a meeting.
However, garage 3 who'd also taken photos etc (and had initially thought likewise) had actually submitted a report and had been told from SEAT HQ that this is a known
problem which is currently under investigation by the factory.
So, persistence prevails and even though it's only the drivers seat that has the
problem, maybe I will get a complete new set of seats with quality material instead of the sub standard stuff that's presently fitted.
All garages will be named and shamed/praised in due course........
