VW Phaeton 3.0 TDI with 240 ps bj 2008 solid model?

Hello dear community, I am currently looking for a Phaeton in the above mentioned version. Can you give me hints for this purchase? Does the engine have special weaknesses? I am well aware of the costs with this car. Is there any competent free workshops or Phaeton drivers in the area Hamburg/Lüneburg who have already built up their network around this beautiful car? So far I have only come across deaf nuts. I hope for numerous profitable feedbacks. Greeting Steffen
