What is the most reliable engine for a Volkswagen Touareg?

I'm considering buying a used Volkswagen Touareg but I'm not sure which engine would be the most reliable. I want something that won't give me any major problems in the long run. What do you suggest?

In my personal experience, the V6 engine has been very reliable and low maintenance. I've had my Touareg for over 5 years now and haven't had any major issues with it.

I've heard great things about the TDI engine, it's known for its durability and fuel efficiency. Definitely worth considering if you want a long-lasting engine.

I would recommend avoiding the V8 engine as it tends to have more issues and is more expensive to maintain. Stick with the V6 or TDI for reliability and cost-effectiveness.
