All....my 3 year warranty bites the big one on 4th september this year.

Can't afford to buy a new GTI just now

and because my car is no good have no need to want one!

I've had the reminder letter from VW they want £401 for a year and no payment terms to extend warranty up to 15,000 miles. I appreciate that there are other independents, who are every bit as good, I am not sold on the vw warranty at all.
Now, this period will take in my 40,000 mile service, thats a biggie I think and if there are any issues perhaps my £401 will be money well spent.
So to assist me make a more balanced decision, ...
is there anyone on here who has significantly benefitted from having extended their warranties into their fourth year? If so can you post please, I rather suspect these extended warranties are all weighted away from the user and that as ever you tend to get nothing for nothing in this world.
Also, did anyone who has completed their 40k service encounter any significant issues that were covered under warranty?
