need advice regarding T5 transporter

What is your question?

Hi, I am looking to purchase a t5 transporter. I had a pre purchase inspection completed by a VW mechanic who reported that the fly wheel was making a rattling noise when in reverse. He went on to recommend a replacement for 2.5k aud. Just wondering if this is a common issue for this make model, it only has 160k km so though that it was odd but I'm not a mechanic!?? Can I keep driving it with a rattle on the fly wheel? Do I need to change it immediately? Whats the worst thing that could happen? Thanks in advance. Lachlan

What makes this problem better or worse?

Reversing, I haven't driven it

How long has your 1990 Volkswagen Vanagon had this problem?

not sure looking to buy
