Does the vw Touareg V6 TDI have a timing belt or chain?

The V6 engine in the Volkswagen Touareg TDI is equipped with a timing chain. Unlike a belt, which needs routine maintenance and replacement, the chain is designed to last the life of the vehicle. However, there are exceptions and replacing this part is costly. The average price to replace the timing chain in this vehicle is $2,350 to $2,800. Labor makes up about $1,740 to $2,200 of that total, so this is very labor-heavy repair work. A common symptom of a failing timing chain is rattling in the engine. The part is made of links and as these links rub against other components, small fragments can break off and land in the oil drain pan. They bounce around and make noise, so if You notice a sound like this coming from the engine compartment, have the vehicle looked at right away. A broken chain can result in expensive engine damage.
