Default Slight hesitation at low revs

Hi all I have a 99 plate 4.2 Quattro sport.

It seems to hesitate under 2500 rpm it goes very well above 3000rpm.

Any suggestions on anything to look at?

Thanks in advance.

Have a look at some of the threads in this section - there are a few discussing similar/same issues. I know that HP sauce (a member) has a thread about a mile long on this!

A mile long and going nowhere..........
(The last suggestion was that it was related to torque converter slip vs lockup which is "locked" in tiptronic mode so potentially testable. Nothing conclusive as yet, but my symptoms, which have been absent recently, may be different anyway).

I have read your thread a couple of times

Mine is hesitant in all gears, in auto or tip until you start getting the revs up, over 3000rpm there is no problems at all.

It can sometimes be worse when it's cold for the first few minutes.

Or faulty coolant temp sensor - I had that and it caused all sorts of oddness, but especially difficult starting.

That gets my vote. The 3-stage manifold flaps operate/change over at 3360rpm (and 5200rpm).

Very easy to check, think it's in engine stickies. Just pop the engine cover off (4 turnscrews) and look at the links. 1 minute initially.
If not broken check they actuate when the engine starts.
