UK-POLOS.NET - THE VW Polo Forum

Does anybody know the TPI for the exhaust cam variator (loose bolts) is online anywhere? Had a conversation with a VW technician and he said there is one, but wouldn’t give me the number. He also said that apparently VW are investigating this problem, as there have been several vehicles in the field with the same problem. VW currently being very tight lipped about it. This is the problem that I posted in the Polo section with the Imgur link to the photos.
Any advice would be gratefully received.
Thx.
