The 2008 AudiA4 uses a timing chain on the engine and this is a better option than using a timing belt. A timing belt usually needs to be replaced every 60,000 to 100,000 miles and a timing chain should usually last over 300,000 miles. The 2008 AudiA4 does have a known issue with the timing chain tensioner and that is something You should have replaced if it has not been replaced in the past. If Your tensioner were to fail it could lead to the chain coming loose and that could damage the timing gears as well as the components in Your engine. You should also change Your water pump every 100,000 miles to make sure that coolant flows well through Your engine.

The 2008 Audi A4 has a timing chain. Though some consider it a lifetime part, many mechanics recommend it be inspected at 70.000 miles.

The 2008 A4 is driven by a timing belt but the DOHCams are each driven by a separate chain. The replacement interval for the belt , water pump and pulleys is 120,000 kilometres or 6 years , whichever comes first. You should also replace the cam follower in the high pressure fuel pump every 100,000 kilometres.
