Dunno how that makes you think that there won't be any DPF problems

lol.
The car has already thrown an error, it is being inspected/fixed by a Seat workshop, so I will ask them to tell me what came up on the scan, and what it was they fixed. I will then be able to make a much more informed decision. My logic tells me if nothing DPF related comes up on the scan, then there isn't a DPF
problem at this point in time. Im not saying there wont be in future, im just saying it has as much chance as the next VAG car I look at.
EDIT: Just checked first post, 16k miles on a 4 year old car? that is RIDICULOUSLY low!
Meaning what? Are you saying its obviously been used on short runs only so inevitable DPF drama brewing or possibly DPF is what the current
problem is? Just for reference, I have only driven 5k in my current car last year, and 4k of that was 4x 900mile journeys between Newcastle and Plymouth - does that sound ridiculously low in that context?
the CR170 isn't fragile as such, just that like every other late model Diesel they have DPF's which cause issues on other manufacturers too.
never had an issue on ours, even with the low mileage, yes it did re-gens but to be honest never really noticed them as such
Why do you think the CR170 is a fragile unit?
To be honest, its the replies on here which are making me fear fragility. Yes I will do some short trips to the shops or whatever, but primarily the reason im buying a diesel is due to my family living the other end of the country. I have been running a 2.0 HDi Pug for the last 13 years and that is why I am looking again for a diesel, and figured the CR170 would provide me some nice economy plus some grins. I prefer everything about it over Golf or A3 alternatives.
Just to bullet point this 'adventure' so far...
1) Finding this 2010 with 16k in MINT condition at a nice price felt like a good thing to start.
2) My initial dismay at the error happening on the test drive prompted this thread.
3) From chatting here, and thinking about it logically, I still think having this error occur has put me in an advantageous position, for the garage selling it are now paying Seat to sort it out.
4) Provided I am happy with what Seat say when I call them, they tell me what came up on their scan and it checks out with what the seller is telling me, and the fault is fixed - I see this as something which you don't normally get when buying a second hand motor - a good thing.
5) So essentially there is no more reason to walk away from this motor or suspect there will be future problems, than any other VAG motor I could choose to buy which doesnt have a scan and remedial action
before I hand over a bag of gold.
Hope ive answered all the Q's!!

I really do appreciate the discussion guys.
