I’ve not had anything from Seat recently.
The original proposed fix called for new injectors on the 1.2/1.6 versions, but just software on the 2.0. That fix was rejected in the US.
last I heard they were looking into a catalyst type fix which would be a huge undertaking as they’d have to design it for dozens of different body type – not to mention it would almost certainly need an Ad Blue diluted piss supply which means fitting some sort of filler for it – the PPI/Personal Injury types are already circling bleating about consumers being lumbered with a “£50 a year” bill for Ad Blue (which is literally cheap as piss, you can buy a lifetimes supply of it for a couple of quid from any service station that caters for trucks) as there doesn’t seem to be much money in delayed flights and PPI is drying up.
My personal opinion is that in the UK and to a lesser extent Europe anyway they’re not spending their time designing a fix, they’re negotiating with governments – the UK has already said that they’re not going to impose anything in regards to this, they’re not reclassifying the cars and they’re not fining VAG, they’re also not going to force VAG to compensate customers as residual prices have been unaffected. So there’s not great desire for them to spend £1000 a vehicle on a new redesigned exhaust system and cat which will probably make them worse to drive. I think they’ll complete a bit of a lip non-mandatory service recall, maybe a remap of sorts and offer some kind of trade-in discount for effected cars.
