Good morning chaps and chapesses.
I am looking at purchasing a 59 plate Golf 1.4 tsi 122 se.
Everything is great about the car, other than an irritating fault which appeared on the test drive.

When exiting a roundabout in 2nd gear at about 20-25mph, under hard acceleration, the car cut all power for a second or two, then back to normal. It seems to happen under firm to hard acceleration.
I feel that it could be either a boost or fuelling issue, but with reading about the chain tensioner issues, it's making me unsure. There are no dash lights on.

Can anyone out there help with any advice?
Even any other hints/tips?

Thanks.
