Passat timing belt Help

[Garbo65]

Hi there, just signed up after googling Passat timing belt replacement and you guys came up, just the thing Ive been looking for as I do all the servicing on the 2008 Passat Tdi, sons 1983 VW van.... cant think of the model!Anyway 4cyl petrol job. And Ive just had a shed built in the backyard, just loving working on the cars on a cement floor and under cover!
So anyway , will be reading the threads on timing belt replacement as Ive just found out Im about 20K overdue
Cheers
