my advice would be to get it done.
When i bought my golf a year ago it had done about 61k miles and one day a few thousand miles later the cambelt broke.
I was stopped at a junction, the second my foot touched the A. pedal to go, it broke. I was Damn lucky i was not on the move cos i was out ragin' it.
VW had to check the insides of my engine to see if it was knackered, turned out the belt had shed a load of teeth, and it all cost ?250 to have a ?70+ job done that should have been done before i even owend my mowta!
Dont wanna scare ya, but i would change it, you need to get it done anyway, next time i'm gonna change on 40k.
My VW garage said they change between 50k/60k if its any help?
