115 BHP PD GOLF TDI 2001.
It will go upto 80mph,then start to drop speed,if i try to go over 80,it will do it but it will take a while.
If i drive it and im in say...3rd gear and i slow down and put it in 2nd gear, if i put my foot down it wont go,slow as a slug!
Also get a vibration underneath the front of the car.
