Hope you don't get the UP. I had one the other week for a day and it was sh!te. Bottom end Vauxhall Corsas are a far better drive.
Indeed bare bones is how I would describe it with a coarse engine note.
I do rate the transmission and I've been on the receiving end of 2 faults on separate cars. The DSG on my MK5 would behave as if the clutches slipped so I restarted the engine and it disappeared, only happened twice but I could see a permanent fault developing in the future.
MK6 GTI - Gearbox replacement was £4200 last year. I paid over £2k after goodwill from VWUK. I remain skeptical about the circumstances of the whole gearbox needing replacement as this appears to be rare.
Sometimes it is best to replace with a new item to ensure further reliability but diagnosis of the fault was not clearly detailed which made me suspicious. These Dealerships like to make money on warranty and goodwill work so perhaps I should have taken it to an Indy first and then weighed up my options regarding repair as the car had no warranty.
