Are there any common issues with the Volkswagen Touareg's engine?

I'm considering purchasing a used Volkswagen Touareg, but I've heard some rumors about engine problems. Can anyone confirm or deny this and offer any advice?

I've been driving my Touareg for over five years and have never had any issues with the engine. Just make sure to keep up with regular maintenance and inspections.

I had a problem with my engine a few years back, but it turned out to be a rare manufacturing defect. The dealership fixed it for free under warranty. Overall, I have been very happy with my Touareg.

I've heard some people have had issues with the diesel engines on older models, but the newer ones seem to have improved greatly. It might be worth doing some research on specific model years before making a decision.
