Do I have to change the cambelt after 7 years, if it's only done low mileage?

Question

Several mechanics have suggested that it isn't necessary to replace the cambelt if the car's travelled less than 10,000 miles even if the vehicle is 7 years old. Is there a way to check if it is needed or if it isn't? The vehicle is an Audi A3.

You can do a visual inspection, to look for signs of wear or cracking.
However I have seen belts that "look" in good condition just "fail"...
But given the cost of the damage if it fails then I would get it replaced, at 7 years old I would think it is a good investment.
Had the belt replaced on my car as it is 15 years old - just good insurance.
Your choice on how you spend your money.

You don't have to do anything, it's a judgement call.
If I remember correctly the service interval for most Audi cam belts is in the range of 70-80k miles, or 5-7 years depending on the engine type. So if you want to or must follow the stated service intervals you should replace the belt.
However, if mechanics with good experience on VW/Audi engines all agree you don't need to replace it yet then that's good evidence you could skip it for now.
