Phaeton 3.0 TDI 2005 jerks, speed swings

Hi people I just registered here, but I’ve been reading with you for 6 years. My thick diva makes a theater again. Built 12/2005 235000km V6 TDI I describe my problem once: On normal ride (all speeds), whether with or without cruise control the rev indicator will hit as soon as the engine has a little “load” ( highway slightly uphill) knocks out of about 200 revolutions. I had the same problem already about 3 years ago. At that time it was an expensive fun. ( Gearbox felt n/ then converters changed/ not all brought 250€ for nix) I read here in a Threat that you should clean the levers of the suction tube adjustment. That I then told my workshop and everything was good again, until now 80000 km later exactly the same, so again with which please clean the suction tube adjustment. But this time it did nothing. I just put almost 4000€ in wear parts and the analysis of the problem but he jolts cheerfully further. Jetz But I didn’t learn anything from it, because I’m looking for a Phaeton again, because it’s just the coolest car and I love the big bitch so much. I’d like to sell the box. Can anyone tell me what the problem can still be??? I don’t want you to be sent to Africa, she finally did great services for 6 years. Greetings And please for your help. PHAETON FAN 😉
