hi all, ive only just joined here and was hoping that some one can help me with a little problem ive got, my car is a 1999 A4 1.9 tdi, the problem is that when my revs reach about 2000 rpm the car feels really hesitant but as soon as you get over 2000 it pulls like normal,the only other little thing is that there seems to be a clunking type of noise from the front end when you go over bumps or put the clutch in quickly when moving in slow mooving traffic,ive looked underneath it but from what i can see its had recent bottom arms, any one help??
