Hello VW fans

I am trying to solve a problem for my daughter who runs a W reg 1.4 16v Polo auto. There is an intermittant stalling problem with the car which usually occurs after a lengthy run. The local VW dealer couldn't find a fault so she took it to a diagnostic man who came up with fault code 1314 but for some reason didn't explain what this meant.

PS. This is my first post and although I don't have a VW at present - I am always looking on ebay for a mint Scirocco. I had a 1988 1.6GT for years and did 200k in it. (best cars ever made)

Cheers
